Single‐atom catalysts (SACs) play a key role in many chemical processes owing to highly desirable atom efficiency, but the challenging synthesis of these catalysts limits their commercialization and application on a large scale. Herein, we report a facile strategy to integrate atomic Pt into richly deficient MoO_3−x. The core of the experimental strategy was the fabrication and utilization of H_xMoO_3−x with plasmon resonance that contained intercalated H⁺. The obtained catalyst was found to possess remarkable electrocatalytic activity toward the hydrogen evolution reaction that was even comparable to that of commercial Pt/C, whereas the amount of Pt used was reduced to only 10 % of the amount of commercial Pt/C used. Therefore, this work not only supplies a new synthesis route to SACs but also reveals the potential relation between plasmon resonance materials and the fabrication of single‐atom catalysts.

氢发生反应的单原子铂催化剂的制备：利用HxMoO3-x等离子体共振的新协议

由于高度希望的原子效率，单原子催化剂（SAC）在许多化学过程中起着关键作用，但是这些催化剂的合成挑战性很大，限制了它们的商业化和大规模应用。在此，我们报告了一种将原子Pt集成到贫富MoO _{3- x中}的简便策略。实验策略的核心是H _x MoO _{3− x}的制造和利用，其等离子共振包含嵌入的H ⁺。发现所获得的催化剂对氢析出反应具有显着的电催化活性，该活性甚至可以与市售Pt / C相当，而所使用的Pt的量减少到仅占市售Pt / C的10％。因此，这项工作不仅为SAC提供了新的合成途径，而且揭示了等离子体共振材料与单原子催化剂的制备之间的潜在关系。
