Electrochemical synthesis of dendritic Pd-CoO/PW₁₀V₂/rGO and its electrocatalytic performance for formic acid oxidation

Abstract

In this paper, the electrodeposition method is used to deposit dendritic Pd-CoO on the surface of Pd/PW10V2/rGO step by step to prepare Pd-CoO/TMSPs/rGO composites. The composite is characterized by XRD,...

“…The size of I D /I G can be regarded as a measure of the degree of defects for carbonaceous materials. 37 The order of decreasing I D /I G is the order of decreasing degree of defects and also the order of decreasing surface area, pore volume, and nitrogen content, which is readily understood when it is realized that developing nanopores and doping nitrogen into the carbon structure bring about the increase in defects. 38…”
