Electrochemical properties and mechanism of CoMoO4@NiWO4 core–shell nanoplates for high-performance supercapacitor electrode application studied via in situ X-ray absorption spectroscopy

Binary metal oxide CoMoO₄@NiWO₄ core–shell nanoplates possess the great electrochemical properties by synergistic effect between the two components. In-situ XAS indicates that the Co and Ni elements are simultaneously participated Faraday reaction.
