电解水制氢提供了一条绿色、可持续的途径。铂（Pt）基材料被认为是析氢反应（HER）的有效电催化剂。然而，Pt基催化剂的大规模商业化受到高成本的困扰。因此，超低Pt负载电催化剂，可以达到低成本和高HER性能的平衡，引起了人们的广泛关注。在这篇综述中，代表性的有前途的合成策略，包括湿化学，退火，电化学，光化学，和原子层沉积进行了总结。此外，还讨论了不同电催化剂组分（过渡金属及其衍生物）与Pt之间的相互作用。值得注意的是，这种相互作用可以有效地加速HER的动力学，增强催化活性。最后，简要讨论了当前的挑战和未来的前景。综述了几种制备超低载铂量析氢电催化剂的方法。此外，不同的催化剂组分和Pt之间的相互作用进行了讨论。综述了过渡金属及其衍生物加速HER反应动力学和提高HER催化活性的作用机理，并提出了今后的研究方向。
Hydrogen production from water electrolysis provides a green and sustainable route. Platinum (Pt)‐based materials have been regarded as efficient electrocatalysts for the hydrogen evolution reaction (HER). However, the large‐scale commercialization of Pt‐based catalysts suffers from the high cost. Therefore, ultralow‐Pt‐loading electrocatalysts, which can reach the balance of low cost and high HER performance, have attracted much attention. In this review, representative promising synthetic strategies, including wet chemistry, annealing, electrochemistry, photochemistry, and atomic layer deposition are summarized. Further, the interaction between different electrocatalyst components (transition metals and their derivatives) and Pt is discussed. Notably, this interaction can effectively accelerate the kinetics of the HER, enhancing the catalytic activity. At last, current challenges and future perspectives are briefly discussed. Several synthesis strategies are reviewed for preparing ultralow‐Pt‐loading electrocatalysts in hydrogen evolution reaction (HER). Furthermore, the interaction between different catalyst components and Pt is discussed. The mechanisms of transition metals and their derivatives to accelerate the kinetics of HER and enhance the HER catalytic activity are summarized and future research directions are proposed.
