摘要
虽然降低Ru- o共价抑制了晶格氧的损失,但它也削弱了Ru- obri - mo构型的电子转移,导致Ru过度氧化。在RuO2中掺杂Mo,削弱了Ru- o的共价,形成了弱的Ru-Mo金属键,以补偿Ru的电子密度,其中Mo0.125Ru0.875O2催化剂在300 mA cm-2下500 h表现出稳定的PEM性能。
Constructing weak Ru–Mo metallic bonds to suppress Ru overoxidation for durable acidic water oxidation†
Although reducing the Ru–O covalency suppresses the loss of lattice oxygen, it also weakens the electron transfer of the Ru–Obri–Mo configuration, leading to Ru overoxidation. Herein, doping Mo into RuO2 weakens the Ru–O covalency and forms weak Ru–Mo metallic bonds to compensate for the electron density of Ru, where the Mo0.125Ru0.875O2 catalyst exhibits stable PEM performance at 300 mA cm−2 for 500 h.
