摘要
Throughout versatile metal compositions and unique structural characteristics,polynary metal atom catalysts(PACs)readily harness synergistic intermetallic effects,significantly boosting the catalytic performances.These catalysts are featured by favorable catalytic activity,stability and selectivity,offering avenues to tackle challenges in energy conversion,environmental protection and chemical synthesis.Nevertheless,an in-depth understanding and comprehensive summary of the structure-performance relationship for the emerging PACs remains elusive.This review embarks from the classification of PACs,delving further into the origins of catalytic activity and mechanisms underpinning performance enhancement.At the beginning,it outlines the fundamental concepts,preparation methods and accurate recognition of PACs.Subsequently,it centers on discussing the origins of activity,strategies for performance optimization,mechanisms of action,and application scenarios across diverse catalytic reactions.Moreover,the unexplored issues and future perspectives of PACs are proposed at the end,stating their pivotal roles in advancing green chemistry and the sustainable energy realm.This review overall aims to provide valuable insight and guidance for the preparation and application of PACs.
