| Abstract | Highly active and stable electrocatalysts that can work well in alkaline media are essential for industrial water electrolysis. Herein, we have reported the growth of P and Co co-doped Ru hybrids (RuCo-P) on carbon cloth (CC) through a hydrothermal treatment and the following phosphorization. The modification of Ru by Co and P doping can tune the electronic structure for efficient water dissociation and hydrogen desorption in alkaline solution. The resulting RuCo-P/CC achieves a record low overpotential of similar to 4 mV to reach a current density of 10 mA cm(-2)for the hydrogen evolution reaction (HER) in 1 M KOH solution, and also shows a small Tafel slope (43 mV dec(-1)) and outstanding long-term stability. The activity of RuCo-P/CC is significantly superior to that of the commercial Pt/C benchmark and other carbon cloth-supported transition metal-based catalysts. The remarkable alkaline HER performance of RuCo-P/CC could be attributed to the synergistic doping of both Co and P that can effectively reduce the water dissociation barrier and optimize the hydrogen adsorption free energy, respectively. |
