Pengcheng Chen is a Heising-Simons Postdoctoral Fellow in the Department of Chemistry, appointed from Spring 2019 to Spring 2021. His research focuses on developing a hybrid nanocatalyst system that integrates semiconductor nanowires and multimetallic nanocrystals. The inherent properties of nanowire arrays, including large surface area and enhanced light scattering/absorption, make nanowire arrays attractive platforms to explore the synergy between multiple metals in a nanocrystal co-catalyst. Nanowires and nanocrystal co-catalysts will be combined to develop superior catalytic systems that increase the sustainability and efficiency of reactions such as water splitting, carbon dioxide reduction, and nitrogen reduction.
Before joining Kavli ENSI, Pengcheng received his Ph.D. in materials science and engineering from Northwestern University. His past research focuses on using scanning probe nanolithography to combinatorially synthesize polyelemental nanostructures and studying the phase-separation behavior of multiple metals at the nanoscale
