The development of efficient catalysts for electrochemical hydrogen evolution is essential for energy conversion technologies. Molybdenum disulfide (MoS2 ) has emerged as a promising electrocatalyst for hydrogen evolution reaction, and its performance greatly depends on its exposed edge sites and conductivity. Layered MoS2 nanosheets supported on a 3D graphene aerogel network (GA-MoS2 ) exhibit significant catalytic activity in hydrogen evolution. The GA-MoS2 composite displays a unique 3D architecture with large active surface areas, leading to high catalytic performance with low overpotential, high current density, and good stability.
开发高效的电化学析氢催化剂对于能量转换技术至关重要。二硫化钼（MoS2）已成为一种有前景的析氢反应电催化剂，其性能很大程度上取决于其暴露的边缘位点和导电性。负载在三维石墨烯气凝胶网络（GA-MoS2）上的层状MoS2纳米片在析氢方面表现出显著的催化活性。GA-MoS2复合材料呈现出具有大活性表面积的独特三维结构，从而具有低过电位、高电流密度和良好稳定性的高催化性能。
