Abstract
AbstractA series of Co9S8 nanoparticles (NPs) embedded, N, S co‐doped mesoporous carbons were synthesized by the combination of evaporation induced self‐assembly (EISA) method and simple pyrolysis method. Melamine formaldehyde (MF) resin was used as carbon and nitrogen precursor. CoCl2 and thiourea were utilized as cobalt and sulfur precursors, respectively. The as‐obtained samples possessed mesoporous structure. The optimized sample of MF4.0T6.0 exhibited excellent electrochemical performance towards hydrogen evolution reaction (HER) in wide pH range, which achieved a current density of 10 mA cm‐2 at 163 mV (pH 0), 149 mV (pH 14), and 325 mV (pH 7).
