B dopant evolution in Pd catalysts after H evolution/oxidation reaction in alkaline environment
Se-Ho Kim, Su-Hyun Yoo, Leonardo Shoji Aota +4
Introduction of interstitial dopants has opened a new pathway to optimize nanoparticle catalytic activity for, e.g., hydrogen evolution/oxidation and other reactions. Here, we disc…

Understanding the degradation of a model Si-anode in Li-ion battery at the atomic-scale
Se-Ho Kim, Kang Dong, Huan Zhao +7
Si-anodes have long been candidates thanks to an expected ten-fold increase in capacity compared to graphite. However, details of the mechanisms governing their degradation remain…

Controlled doping of electrocatalysts through engineering impurities
Se-Ho Kim, Su-Hyun Yoo, Sangyong Shin +9
Fuel cells recombine water from H2 and O2 thereby powering e.g. cars or houses with no direct carbon emission. In anion-exchange membrane fuel cells (AEMFCs), to reach high power d…
