Constructing Gradient Orbital Coupling to Induce Reactive Metal–Support Interaction in Pt-Carbide Electrocatalysts for Efficient Methanol Oxidation

Reactive metal-support interaction (RMSI) is an emerging way to regulate the catalytic performance for supported metal catalysts. However, the induction of RMSI by the thermal reduction is often accompanied by the encapsulation effect on metals, which limits the mechanism research and applications of RMSI. In this work, a gradient orbital coupling construction strategy was successfully developed to induce RMSI in Pt-carbide system without a reductant, leading to the formation of L1
