Abstract Constructing synergistic dual sites has been well‐recognized as an updated avenue in constructing binary‐component Pt/support compounds such materials undergo undesirable interfacial barriers and complicated synthesis. Here integration of ultrafine Pt nanocrystals on oxygen‐deficient CoMoO 4 nanosheets is reported that achieved superior alkaline hydrogen evolution reaction (HER) activity (110 mV @ 1000 mA cm −2 ) with a reversed deliver effect between bifunctional active sites. With perceptions from comprehensive experimental theoretical results, the HER process occurs three steps: pronounced water dissociation capability , facile transfer to nanoparticles, optimized desorption catalytic site. Thanks site effect, Pt/CoMoO catalyst boosts large‐density seawater electrolysis anion exchange membrane electrolyzer (AEM). This work not only provides valid intensification strategy aimed at support‐type electrocatalysts but also takes insights into dual‐site mechanisms for high‐performance HER.
