Molecules derived from biomass are typically highly oxygenated, and require chemical transformations before they can be used as fuels or for the production of chemical products. One common transformation is hydrogenation – that is the addition of hydrogen – which is conventionally done using hydrogen gas (H2), high temperatures and pressures, and expensive catalysts such as platinum or palladium. However, Wenzhen Li – Richard Seagrave Associate Professor of Chemical and Biological Engineering – and coworkers are studying an alternative process in which hydrogenations can occur at mild conditions by applying a small electrical voltage to metal electrodes.

Electrocatalytic hydrogenation

The process is called electrocatalytic hydrogenation (ECH), and Li says it has many advantages over traditional methods. In ECH, hydrogen atoms are generated electrochemically from water, therefore avoiding the kinetic barriers and challenges of H2 activation. This means that the reactions can be performed without the need for external H2 supply, at room temperature and ambient pressure, and on inexpensive metal electrodes. Moreover, because the reactions are driven by electricity, the energy input can potentially be supplied from renewable sources such as wind and solar power.

Insight leads to tunability

A key challenge of ECH is to achieve high selectivity and electron efficiency to the target products. For example, an undesired reaction that may occur is the coupling of two substrate molecules to form dimer products. Additionally, water, which is used as the solvent, may react at the electrode to generate H2 gas, resulting in lower efficiency for ECH and higher electricity demand.

This diagram is one that appears with the paper on the Li Group research that has been published in the Journal of the American Chemical Society.

“There are big understanding gaps about the actual mechanisms occurring at the metal surface, and little is known about the relationship between reaction conditions and selectivity,” said Li. His recent research focuses on distinguishing different mechanisms occurring during the ECH of furfural, a molecule derived from sugars. For this reaction, an inexpensive and Earth-abundant metal, copper, is used as the electrode material to selectively generate furfuryl alcohol, an important industrial chemical, or 2-methyfuran, a promising biofuel. “I am very proud of our work because we acquired new understanding of electrochemical reduction mechanisms by cleverly combining various experimental tools and sophisticated techniques,” said Li.

Xiaotong Chadderdon, a Ph.D. candidate in Li’s research group, explained “the insight gained about the different surface processes allowed us to rationally choose conditions, such as the electrical voltage and electrolyte pH, in order to maximize the desired reactions.”

Their findings were published in a recent issue of the Journal of the American Chemical Society, in an article titled “Mechanisms of Furfural Reduction on Metal Electrodes: Distinguishing Pathways for Selective Hydrogenation of Bioderived Oxygenates” (DOI: 10.1021/jacs.7b06331). Xiaotong is a co-first author of the article along with David Chadderdon, who is also a Ph.D. candidate in Li’s group. Additional co-authors are Jean-Phillipe Tessonnier, Assistant Professor of Chemical and Biological Engineering; Dr. John Matthiesen, a Ph.D. graduate of Tessonnier’s group; Dr. Jack Carraher. a former post-doctoral researcher in Tessonnier’s group; and Yang Qiu, a Ph.D. candidate in Li’s group. Li and Tessonnier groups worked closely together on the project, which was supported by funds from the U.S. National Science Foundation.

Toward a sustainable future

Professor Li has high hopes that electrochemistry will be a key part of sustainable chemical and fuel production in the future.

“The electrochemical approach is unique, because it takes advantage of both renewable carbon in the form of biomass-derived feedstocks and renewable electricity, which is expected to become more abundant and inexpensive in the future,” said Li. “Our recent findings are not only applicable to furfural, but can potentially be extended to the ECH of different biomass-derived chemicals and to other challenging electrochemical reactions.”

He also foresees opportunities in the future to replace copper with light-absorbing semiconductor electrodes – which could be used to harness energy directly from sunlight to drive electrochemical reactions.

Large CBE student contingent at conference includes Chem-E-Car team

The Lime-E-Lanturns Chem-E-Car team prepares for a run.

Eighteen undergraduate students representing Iowa State University’s Department of Chemical and Biological Engineering took part in the American Institute of Chemical Engineers (AIChE) Annual Meeting in Minneapolis.

The event brings together chemical engineering students, educators, industry professionals and more from around the nation to attend information sessions, networking events, competitions and more, in what is considered the field’s premier forum.

One of the highlights of the event is the ever-popular Chem-E-Car competition, which involves university student teams each designing and constructing a miniature car that runs a straight-line course, powered and stopped by chemical processes.

Students at meeting

With a second-place finish in the AIChE regional student conference last spring, Iowa State’s “Lime-E-Lanturns” team qualified for the national competition held during the conference in Minneapolis, the second consecutive year Iowa State’s chapter had earned a berth in the nationals. Their final run saw the car travel to 5.34 meters from the finish line, good for a 22nd place finish. A total of 40 teams participated.

In the research poster competition, ISU’s Maxsam Donta took second place in his division.

Mazsam Donta discusses his research poster with professor Tom Mansell in a practice session at the recent CBE Showcase. His presentation netted second place in his division at the AIChE Annual Meeting.

Jamie Pryhuber, a CBE senior, said of her experience, “With the Chem E Car team, I learned how to deal with high stress situations such as forgetting a data set in our documentation package in order to pass the safety inspection – but this also proved the amazing teamwork within Chem-E-Car when we solved our issues and passed inspection. Through being a student volunteer at the conference, I had the experience of mingling with other universities, witnessing panels, and being a friendly face to anyone in attendance. The undergraduate research poster competition at the end of the conference was a great was to finish, since I had the chance to speak to interested professors and students, as well as share my excitement about biological engineering. Overall, the conference is a very rewarding experience if you are involved.”

Chem-E-Car team leader Alex Sazinski, who was attending the Annual Meeting for the first time, said overall he was very pleased with the team’s effort. He explained that in testing the team only had the car’s unusual aluminum air battery activated for short periods of time, but in the competition it was active for a longer period of time, which used up more of its resources and robbed the car of some power, resulting in a shorter-than-hoped-for run. But, he said, the car’s battery system turned heads and spurred interest. “As our team had that fairly unique power mechanism, many teams inquired how to build a similar battery without causing it to short and to generate enough power.”

Sazinski also pointed out the team was under time pressures to prepare for the Annual Meeting competition. “Due to being on the team that made it to this conference for the first time ever last year, we were not able to start construction of our car until early spring of this year. This is short in contrast with other schools who normally begin construction in the fall semester, about a year in advance. We managed to make a power mechanism that had failed for the last two years consecutively at the regional conference work, and we used it to earn second place in the regionals and move on to nationals for the second time.”
The Iowa State CBE students who participated in the AIChE Annual Meeting included Vince Anderson, Martin Asama, Derek Bruun, Maxsam Donta, Trang Hoang, Carolyn Jennrich, Jennie Larson, James Lichty, Andy Mettry, Akash Mitra, Alexandria Mullally, Josh Potvin, Jamie Pryhuber, Alex Sazenski, Kristian Shipley, Skyler Streff, Shawn Van Bruggen and Austin Weiser. Professor Stephanie Loveland was the faculty mentor.

Teamwork takes flight with paper helicopters in CBE class

Professor Reuel confers with a student during the helicopter construction phase
3-2-1, drop! A couple of test helicopters make their way to the floor.

Chemical and Biological Engineering undergraduates in professor Nigel Reuel’s Computational Methods in Chemical Engineering class learned about functioning as a team under time constraints with a recent exercise that involved applying design of experiment (DoE) principles to create the optimal paper helicopter.

The debut of the activity turned teams of students loose with paper, scissors, a diagram and instructions to perform such tasks as identifying three significant design variables, creating a response surface design, collecting time of flight data, and fitting the data to a quadratic model to identify the optimal design, all in an hour time period. Helicopter models were crafted and dropped while their descents to the floor were timed by team members. Each team then offered up their best model in a face-off where the last helicopter to hit the floor was the overall winner.

Reuel said the teams of students have been working together on other assignments in the class this semester as well. Referring to the groups as “start-ups,” Reuel puts together students with similar career sector interests and allows them to function as teams in many ways both inside and outside of class to simulate real-world scenarios in team-based engineering work. The winning team on this day was the agricultural engineering-oriented group.

Eclipse curriculum! Ch E 325 shines a different light on data collection with solar event

CBE students (left to right) junior Sophie Masters, senior Makayla Moccio, senior Brandon Korkow and senior Luvern “Trey” Wooge collect and record data during the class eclipse exercise.

It was a case of thinking outside the box – with the “box” being the conventional classroom.

CBE professor Stephanie Loveland decided to turn the August 21 solar eclipse into a living laboratory of data collection for her Ch E 325 (CH E Laboratory I) class. And so, with notepads, clipboards, digital thermometers and eclipse-viewing glasses in hand, she and her Chemical and Biological Engineering undergrads spent their first class period of the semester observing the solar eclipse, and recording data about the event. “Rather than the usual first-day syllabus, I decided we’d head outside to take data about the eclipse and practice writing a report about it during the next class period – instead of just working with the usual random data,” said Loveland.

Senior Ashley Iannuzzelli shows a digital thermometer used to record air temperature during the eclipse.

Despite the heavy cloud cover that got in the way of any unobstructed eclipse viewing, the sun was revealed a couple of brief times during the class observation, with one of the times being just four minutes before the maximum of the eclipse.

Time for viewing glasses and devices as the sun briefly breaks through the clouds.

In fact, the cloud cover will be used as an example of “confounding data” when it is analyzed by the students. Using digital thermometers, they took note of the temperature drop that occurred during the eclipse, coming up with a decline of about seven degrees. But, as Loveland will ask, how much effect did the clouds have on the temperature drop, as opposed to simply the eclipse alone?

Though the clouds nearly won the day, Loveland is hopeful the students enjoyed a break from the norm, and enjoyed the chance to shine a different light on the subject of data collection.

year at Rice. “You don’t know all the answers, but you try something new each day to get there. It’s very valuable because the sooner I can start working in research, the better.”

Matthew Burroughs discusses his research with graduate student Jake Nuhn, one of the program facilitators.

“The graduate school representative who came to talk to us was really great, and really helped me with making decisions about the direction I want to go in the future,” said Mededovic, who added, “The involvement of everyone here in amazing. Even though Dr. Mallapragada is a very busy person, when I would email her a question I’d have a response within an hour.”

“I wasn’t sure about graduate school, but this program gave me the confidence to know that I can do it,” said Burroughs.

The program is funded by the National Science Foundation and will be held again in CBE during the summer of 2018. More information and registration will be available early next year. General information about the program can be found on the CBE web site.
