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.
表面氢效应对钙钛矿 Ca0.9 Yb0.1 MnO3 中的纯电子态跃迁进行调制，协同产生更合适的 eg 电子填充状态和更好的导电性。这使得其催化活性比原始样品提高了 100 倍。
