The recent surge in interest in the utilisation of transition metal dichalcogenides for the hydrogen evolution reaction (HER), as well as the long-standing problem of sulfur poisoning suffered by the established Pt HER electrocatalyst, motivated us to examine the impacts of sulfur poisoning on both emergent and current electrocatalysts. Through a comparative study between MoS2 and Pt/C on the effects of sulfur poisoning, we demonstrate that MoS2 is not invulnerable to poisoning. Additionally, using X-ray photoelectron spectroscopy, correlations have also been established between the atomic percentages of Pt-S bonds and normalised HER parameters e.g. Tafel slope and potential at -10 mA cm(-2). These findings are of high importance for potential hydrogen evolution catalysis.
