Fabrication of Ru nanoclusters on Co-doped NiSe nanorods with efficient electrocatalytic activity towards alkaline hydrogen evolutionviahydrogen spillover effect

The hydrogen spillover strategy was demonstrated to enhance the HER activity of Ru in alkaline electrolytes through Co doping into NiSe. 1.5 wt% Ru–Ni 0.85 Co 0.15 Se/NF with a smaller |Δ Φ | value showed a superior HER performance and stability.
