ABSTRACT
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, in which the MoS2 nanotubes were loaded with TiO2 nanoparticles, have been synthesized via a facile solvothermal and hydrothermal method. The as-prepared TiO2/MoS2-NTs electrocatalyst demonstrated enhanced electrocatalytic hydrogen evolution performance compared with MoS2-NTs. Electrochemical measurements reveal the overpotential and Tafel slope of as-prepared TiO2/MoS2-NTs are -0.21 V and 42 mV dec-1. The HER improvement is proposed to be attributed to the increased edge sites results from the interfaces and synergic effect between TiO2 nanoparticles and MoS2 nanotubes.
