采用Mo衬底原位硫化法制备了对析氢反应具有高活性的非晶态MoS_2多孔薄膜。薄膜具有较小的过电位(接近120 mV)和较低的塔菲尔斜率(接近41 mV dec(-1))，其优异性能归功于非晶态结构、多孔结构和优化厚度的结合。
Amorphous MoS2 porous thin films (denoted as MoS2 PTFs) with high activity towards hydrogen evolution reaction (HER) were fabricated by in situ sulfuration of a Mo substrate. A small overpotential (similar to 120 mV) and a low Tafel slope (similar to 41 mV dec(-1)) can be observed and their excellent performance was ascribed to the combination of the amorphous feature, porous structure and optimized thickness.
