摘要：
It is significant to develop highly efficient and cost-effective hydrogen evolution reaction (HER) electrocatalysts. Herein, we propose an efficient fabrication of Ni-S/MoS2 hybrid nanoflowers grown on Ti foil (Ni-S/MoS2/Ti) via a simple one-step hydrothermal reaction method. When used as a HER catalyst, Ni-S/MoS2/Ti exhibits superior HER performances compared with MoS2 grown on Ti foil (MoS2/Ti) and Ni-S adsorbed on Ti foil (Ni-S/Ti) counterparts in acid media, due to its increased active surface area, enhanced electrical conductivity and syn-ergistic effects from the coexistence of bimetallic sulfides. Additionally, Ni-S/MoS2/Ti demonstrates good HER durability, resisting the acid corrosion during HER process.
