摘　　要：Pt-based electrocatalysts hold great promise for key electrocatalytic reactions in hydrogen-related energy conversion devices.Generally,the catalytic performance is significantly influenced by metal-support interactions(MSI)in the catalysts,making the tuning of MSI in Pt-based catalysts a highly intriguing research focus.In this review,the catalytic mechanism of Pt-based electrocatalysts is firstly introduced.Subsequently,the effects of MSI on supported Pt electrocatalysts are summarized into four types:geometric effects,electronic effects,synergistic effects,and structural reconfiguration.Finally,the prospect of optimizing the performance of Pt-based electrocatalysts by engineering MSI is exhibited,with the aim of inspiring innovation and advancement of supported Pt catalysts,thereby facilitating the development and utilization of hydrogen energy.
