Abstract

Pt-based intermetallics exhibit distinctive physicochemical properties for electrocatalytic and thermocatalytic applications. It has been recognized that their catalytic performance is determined by their composition, configuration and surface structure. In this review, we summarize the advancements in the structural optimization of Pt-based intermetallic catalysts. We first introduce the crystal structures of Pt-based intermetallics, followed by a recapitulation of the thermodynamic and kinetic theory used to achieve these structures. Then, the optimization strategies, including ordering approaches and crystal regulation methods, are summarized. Furthermore, we delve into a discussion on the enhanced catalytic functions of Pt-based intermetallics in electrocatalysis and thermocatalysis. Finally, we outline future research directions focused on the practical industrial applications. We believe this review can inspire further exploration of materials for catalytic applications.
