A nanoflower-like MoO₂–Rh electrocatalyst exhibits a 3.5-fold higher mass activity in the hydrazine oxidation reaction compared with metallic Rh, attributed to the hydrogen spillover, acting as a hydrogen pump to deplete hydrogen from the Rh active site.

氢气溢出，提高对肼氧化的催化活性


与金属 Rh 相比，纳米花状 MoO_2-Rh 电催化剂在肼氧化反应中的质量活性高 3.5 倍，这归因于氢溢出，充当氢泵以耗尽 Rh 活性位点的氢气。
