Abstract

En 中文

• Fundamental concepts and properties of Pt single-atom alloys (Pt SAACs) are introduced. • Characterizations of Pt SAACs are discussed from the perspectives of direct imaging and internal analysis. • Synthesis strategies and characteristics of Pt SAACs are summarized. • Regulatory mechanisms of Pt SAACs on ORR activity are discussed. • Current challenges and applications of Pt SAACs in PEMFCs are presented.
