Tugrul and Woong are joining the lab as postdocs.
Tugrul Ertugrul (left) is a postdoctoral research assistant at the University of Tennessee in Dr. Matthew Mench’s Electrochemical Energy Storage and Conversion Laboratory. He recently received his PhD in mechanical engineering and minor in computational science from the University of Tennessee. His PhD dissertation mainly focused on determining mass transport parameters in vanadium redox flow battery (VRFB) porous electrodes. His research interests also include electrochemical energy conversion and storage systems such as fuel cells (SOFC, PEM), Li-ion batteries and PEM electrolyzers.
Woong Choi (right) received his Ph.D.(2018) in Chemistry at Korea Advanced Institution of Science and Technology (KAIST). He worked as a postdoctoral researcher under the direction of Prof. Hyunjoon Song at KAIST. During his Ph.D., he had studied the design of metal and semiconductor nanostructures as photo- and electro-catalysts for energy conversion. His research interest is in designing an efficient electrochemical CO2 reduction reaction system.
Congratulations to first year, Sidd Rajupet, for winning the DoD National Defense Science and Engineering Graduate (NDSEG) fellowship!
Paper is titled: "Membrane-electrode assembly design parameters for optimal CO2 reduction" doi.org/10.1002/elsa.202100186
In this work:
- A Ag CO2R membrane-electrode assembly (MEA) that operates between 200 mA cm-2 and 1 A cm-2 with CO FEs of 78–91% is developed via systematic engineering of the cathode catalyst-ionomer microenvironment
- Quantified the role of the cathodic ionomer-to-catalyst (I:Cat) ratio, catalyst loading, catalyst-layer thickness, and anode exchange-solution concentration on CO2R activity, cell potential, and selectivity for the first time to result in optimized design and operating conditions.
Schematic shows the catalyst-layer microenvironment and ionomer-catalyst distribution on a catalyst and support nanostructure based on the I:Cat ratio and ionomer content/coverage.
