摘要

Noble metal-based intermetallics are promising electrocatalysts for sustainable energy conversion and consumption processes.High-temperature pyrolysis(＞500℃)methods are used to control their crys-talline orderings,critical to their electrocatalytic activity and durability.However,the high temperature would cause severe aggregation,resulting in a low catalytic active surface area.Significant research efforts have been devoted to addressing this issue.This short review summarizes recent research pro-gress on synthesizing noble metal-based intermetallic electrocatalysts by space-confined pyrolysis.We focus on three strategies:isolation in pores,coverture by shells,and immobilization by salts.The advan-tages and existing problems of different methods are highlighted.Last,important issues to be addressed in future research are also discussed.We hope that this article will stimulate future research to develop high-performance intermetallic catalysts for practical applications.
