Engineering the Electronic State of a Perovskite Electrocatalyst forn Synergistically Enhanced Oxygen Evolution Reaction

摘要

A surface hydrogen effect to modulate the pure electronic-state transition in perovskite Ca0.9Yb0.1MnO3 synergistically generates a more suitable e(g) electron filling status and better conductivity. This achieves 100 times higher catalytic activity compared to that of a pristine sample.
