In recent years, development to increase the performance of Pt-based catalysts and reduce the cost has received significant attention. Among them, the preparation of Pt-based catalysts with high atom utilization efficiency can induce more active sites between the Pt atoms and participating molecules, resulting in improved mass activity. In addition, the combination of high atom utilization efficiency with well-controlled surface structure and composition could boost the mass activity for Pt-based catalysts. This review describes recent progress in the design and synthesis of Pt-based catalysts with high atom utilization efficiency and their enhanced catalytic performance in electrochemical catalytic reactions. The significance for the fabrication of nanostructures and single atom catalysts with high atom utilization will be presented in the introduction section. We discuss the synthetic strategies according to two routes: (1) the rational design of Pt nanostructures, including porous, nanowire, core–shell and hollow structures; and (2) preparation of Pt single atom catalysts and the stabilization of single atoms. Additionally, we discuss the superior electro-catalytic applications of Pt-based catalysts with high atom utilization efficiency. These recent advancements in rational design of Pt-based catalysts offer numerous cases for potential industrialized catalysts with high mass activity and reduced cost in the future.

具有高原子利用率的基于Pt的电催化剂：从纳米结构到单个原子

近年来，关于提高Pt基催化剂的性能并降低成本的开发受到了极大的关注。其中，制备具有高原子利用效率的Pt基催化剂可以在Pt原子和参与分子之间诱导更多的活性位点，从而提高质量活性。另外，高原子利用效率与良好控制的表面结构和组成相结合可以提高Pt基催化剂的质量活性。这篇综述描述了具有高原子利用效率的Pt基催化剂的设计和合成及其在电化学催化反应中增强的催化性能的最新进展。引言部分将介绍制造具有高原子利用率的纳米结构和单原子催化剂的重要性。我们根据两种途径讨论了合成策略：（1）铂纳米结构的合理设计，包括多孔，纳米线，核-壳和中空结构；（2）Pt单原子催化剂的制备和单原子的稳定化。此外，我们讨论了具有高原子利用效率的Pt基催化剂的优异电催化应用。Pt基催化剂的合理设计方面的这些最新进展为未来具有高质量活性和降低成本的潜在工业化催化剂提供了众多案例。包括多孔，纳米线，核-壳和中空结构；（2）Pt单原子催化剂的制备和单原子的稳定化。此外，我们讨论了具有高原子利用效率的Pt基催化剂的优异电催化应用。Pt基催化剂的合理设计方面的这些最新进展为未来具有高质量活性和降低成本的潜在工业化催化剂提供了众多案例。包括多孔，纳米线，核-壳和中空结构；（2）Pt单原子催化剂的制备和单原子的稳定化。此外，我们讨论了具有高原子利用效率的Pt基催化剂的优异电催化应用。Pt基催化剂的合理设计方面的这些最新进展为未来具有高质量活性和降低成本的潜在工业化催化剂提供了众多案例。
