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…
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…
Origins of the hydrogen signal in atom probe tomography
Su-Hyun Yoo, Se-Ho Kim, Eric Woods +3
Atom Probe Tomography (APT) analysis is being actively used to provide near-atomic-scale information on the composition of complex materials in three-dimensions. In recent years, t…
Understanding alkali contamination in colloidal nanomaterials to unlock grain boundary impurity engineering
Se-Ho Kim, Su-Hyun Yoo, Poulami Chakraborty +10
Metal nano-aerogels combine a large surface area, a high structural stability, and a high catalytic activity towards a variety of chemical reactions. The performance of such nanost…
