Integrating metal-based species with a carbon matrix is promising approach for fabricating inexpensive, durable, and efficient electrocatalysts. Herein, NiSe2-decorated N-doped polyhedra (NC) are prepared as electrocatalysts hydrogen evolution reaction (HER) by template-assisted approach. The optimal NC-NiSe2 delivers extraordinary catalytic activities toward HER in wide pH range, overpotentials of 127 mV 0.5 M H2SO4, 226 1 PBS, 205 KOH to drive current density 10 mA cm–2. In addition, this catalyst undergoes fast kinetics via Volmer–Heyrovsky mechanism exhibits excelent long-term durability 48 h the full media. During electrocatalysis, when electrons pass through NC surface NiSe2 particles, water molecules at active sites reduced, then released. excellent activity mainly benefit from hierarchically porous architecture well synergistic interaction nanoparticles matrix, which not only significantly boost electronic conductivity generate plentiful but also guarantee chemical structural stabilities species. This work unravels deep insights into exploration carbon-supported metal chalcogenides highly full-pH values.
