Development of highly active, cost effective, stable and earth abundant electrocatalyst for hydrogen evolution reaction (HER) is still a major challenge for energy conversion technologies. At present, MoS2 and its derivatives have attracted intensive interest due to its excellent catalytic performance. However, improving the overall catalytic activity of structural modified MoS2 is still remains a key challenge for further reducing a overpotential for the HER of electrochemical water splitting. In this regard, we report a surface modified molybdenum sulphoselenide with phosphorous on carbon fiber paper (P-MoSxSey/CFP) for the HER. Remarkably, P-MoSxSey/CFP electrode delivered a low over potential (ɳ) of 93 mV at a current density (j) of 10 mA/cm2 in 0.5M H2SO4, when compared with MoS2/CFP (ɳ=242 mV @ 10 mA/cm2), MoSxSey/CFP (ɳ=200 mV @ 10 mA/cm2). Moreover, the observed HER activity of P-MoSxSey/CFP has outperformed over the current molybdenum phosphides and chalcogenides catalysts. |
