title: Engineering the electronic state of a perovskite electrocatalyst for synergistically enhanced oxygen evolution reaction.
abstract: A surface hydrogen effect to modulate the pure electronic-state transition in perovskite Ca0.9 Yb0.1 MnO3 synergistically generates a more suitable eg electron filling status and better conductivity. This achieves 100 times higher catalytic activity compared to that of a pristine sample.
