High area NiMo−RuO2 composite coating as hydrogen electrode

The preparation method of NiMo RuO 2 composite coating, micrographic surface feature and roughness factor of the coating, influence of content of RuO 2 on electrocatalytic activity, steady state polarization curves and electrochemical parameters, and stability of the electrode in 30% KOH contaning 10×10 -6 Fe 3+ were repored. Experement results showed the NiMo RuO 2 electrode has more excellent electrocatalytic activity and stability than NiMo electrode.
