Electrocatalytic Oxygen Evolution: Discontinuity‐Enhanced Thin Film Electrocatalytic Oxygen Evolution (Small 50/2019)

Discontinuous cobalt manganese oxyhydroxide (CMOH) film shows much higher atom efficiency and performance in the oxygen evolution reaction (OER) than the completely continuous ones. In article number 1903363, Jiaxing Huang, and Chun-Hu Chen, and co-workers prove that the heterojunction edges are responsible for the OER enhancement with facilitated charge transport and kinetics. This concept is highly valuable for reducing the catalysts dosage but gaining even better, durable OER activities.
