Abstract

Bimetallic and trimetallic alloys are widely used as catalysts for the oxygen evolution reaction (OER) and other electrocatalytic processes. We employed a scanning electrochemical microscope (SECM) and finite-element simulations to investigate the OER at single FeCo and FeCoNi hydroxide nanoneedles and observed different distributions of catalytic activity on bimetallic and trimetallic particles.
