外文摘要：Exploring advanced platinum(Pt)-based elec-trocatalysts is vital for the widespread implementation of proton exchange membrane fuel cells(PEMFCs).Morpho-logy control represents an effective strategy to optimize the behavior of Pt catalysts.In this work,an attempt is made to comprehensively review the effect of morphology control on the catalytic behavior of catalysts in the oxygen reduction reaction(ORR).First,the fundamental physico-chemical changes behind morphology control,including exposing more active sites,generating appropriate lattice strains,and forming different crystalline surfaces,are highlighted.Then,recently developed strategies for tuning the morphologies of electrocatalysts,including core-shell structures,hollow structures,nanocages,nanowires,and nanosheets,are comprehensively summarized.Finally,an outlook on the future development of morphology control of Pt catalysts is presented,including rational design strategies,advanced in situ characterization techniques,novel artificial intelligence,and mechanical learning.This work is intended to provide valuable insights into designing the morphology and technological innovation of efficient redox electrocatalysts in fuel cells.
