摘要: Efficient and stable non-precious metal catalysts composed of earth-abundant elements are crucial to the hydrogen evolution reaction (HER) in high-energy conversion efficiency. Herein, TiO2/MoS2-NTs catalyst, which MoS2 nanotubes were loaded with TiO2 nanoparticles, have been synthesized via a facile solvothermal hydrothermal method. The as-prepared electrocatalyst demonstrated enhanced electrocatalytic performance compared MoS2-NTs. Electrochemical measurements reveal overpotential Tafel slope −0.21 V 42 mV dec−1. HER improvement is proposed be attributed increased edge sites results from interfaces synergic effect between nanoparticles nanotubes.
