Abstract

We report on a favorable synergy effect generated between molybdenum disulfide and different carbon supports. While MoS_x 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.
