Descrição: Hydrogen is considered the most likely alternative clean energy fuel to traditional fossil fuels. One of the most attractive hydrogen production strategies is water splitting, but the need for expensive Pt precious metal catalysts to catalyze the hydrogen evolution reaction（HER） is a problem. Recently, two-dimensional transition metal dichalcogenides（TMDs）, especially MoS2, have attracted intense interest as a non-precious metal HER catalyst due to their low cost and relatively high catalytic activity.However, their poor electron conductivity and the limited number of active sites at their edges have greatly limited their overall catalytic performance. We report the direct growth of three representative TMDs（MoS2, NbS2 and WS2） on a conductive carbon paper substrate using chemical vapor deposition and have studied the effects of temperature and gas flow rate on their morphology and structure. All the as-grown TMDs have a 2D nanosheet morphology and were aligned perpendicular to the carbon paper. The WS2 nanos
