ABSTRACT
The development of efficient catalysts for hydrogen evolution reaction (HER) from water splitting is one of the most promising strategies to achieve the goal of peak carbon dioxide emissions and carbon neutrality. Herein, Ru nanoclusters decorated MoSe2 nanosheets supported on a Crepis tectorum fluff biomass-derived hollow carbon tube (Ru-MoSe2/CMT) are prepared as the HER catalysts in both alkaline and acidic conditions. The Ru modification induces the transformation of MoSe2 from 2H phase to 1T phase. Benefiting from the strong water dissociation ability of Ru, Ru-MoSe2/CMT exhibits a low overpotential of 70 mV with a Tafel slope of 39 mV dec-1 in 1 M KOH. Furthermore, the assembled Ru-MoSe2/CMT || RuO2 system with a low cell voltage of 1.54 V at 10 mA cm-2 exhibits outstanding overall water splitting performance superior to Pt/C || RuO2 system. The Ru-MoSe2/CMT || RuO2 system also achieves the excellent stability of up to 30 h in 1 M KOH. The synergy effect between Ru and MoSe2, as well as the improved electron transfer kinetics provided by the biomass-derived carbon substrate together contribute to the excellent HER activity of Ru-MoSe2/CMT.
