【 摘 要 】

Densely aligned CoS₂ nanowires (NWs) on chemically durable stainless steel fibers felt (SSF) substates were synthesized by thermal sulfuring Co₃O₄ NWs, which were oxidized from hydrothermal synthesized Co(OH)_y(CO₃)_(1−0.5y)·nH₂O NWs precursors. The effect of sulfuration temperature on the composition, morphology, and HER performance of the products was studied in detail. The results show that the high purity together with the enlarged density of active sites given by the twisted morphology of the CoS₂ NWs sulfured at 500 °C guarantee its superior hydrogen evolution reaction (HER) performance compared with other samples sulfured at lower temperatures.
