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))center dot nH(2)O 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 degrees C guarantee its superior hydrogen evolution reaction (HER) performance compared with other samples sulfured at lower temperatures.
