Tuning metal-support interaction of Pt-based electrocatalysts for hydrogen energy conversion

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.
