N2 - We report on a favorable synergy effect generated between molybdenum disulfide and different carbon supports. While MoSx species were generated by hydrolysis of [MoS4]2− in water, UV-light was employed to assist the MoS2 synthesis. It was found that the UV-assisted approach, combined with carbon supports properties, boosted the HER activity in acid solution. The synergy phenomenon between MoS2 and carbon supports was centered on sp3-like (C-defects) and sp2 domains of carbon of graphite powder (PG), multi-walled carbon nanotubes (CNT) or carbon Vulcan-XC-72 (C). The HER electrochemical kinetics on MoS2/CNT and MoS2/C proceeded via the Volmer-Heyrovsky mechanism. The stability and kinetic performance were attributed to the strong interaction between MoS2 and the surface nature of the carbon support.
