Advanced electrocatalytic properties of nano-CoWO(4) and CoWO(4)/nitrogen-doped graphene oxide as the anode materials of water electrolysis

The electrocatalytic performance of tungsten-based compounds was significantly enhanced via the crystal facets engineering, defect tuning, and combination with conductive 2D materials. Stating from Na(2)WO(4)·2H(2)O and CoCl(2)·6H(2)O we synthesized two types of nano-CoWO(4) with different morpholog...

description The electrocatalytic performance of tungsten-based compounds was significantly enhanced via the crystal facets engineering, defect tuning, and combination with conductive 2D materials. Stating from Na(2)WO(4)·2H(2)O and CoCl(2)·6H(2)O we synthesized two types of nano-CoWO(4) with different morphologies. The products were characterized by XRD, FE-SEM, HRTEM, XPS and EDS in details. The electrochemical performance of CoWO(4) nanorods was obviously superior to CoWO(4) nanodots due to the enhanced electrochemical active areas. Furthermore, CoWO(4) and nitrogen-doped graphene oxides (NGO) composites were obtained under the similar synthetic conditions. As expected, the CoWO(4)/NGO composites showed significant improvement on electrochemical properties.
