摘要：

Although Pt is an ideal electrocatalyst for hydrogen evolution reaction (HER), in addition to high cost and scarcity, Pt nanocatalysts suffer from low water dissociation rates and poor stability. Herein, we used graphitized wood-derived carbon (GWC) as a platform to construct dual-active catalytic sites via Pt-Ni recombination and modulate interactions of heterointerface atoms through in situ phase transition to improve HER activity and durability of Pt nanocatalysts. Specifically, Ni(OH)2 nanosheets were grown on GWC; then, Pt nanoparticles we...
