Study of electro-catalytic properties of carbon-encapsulated copper nanoparticles

A glass carbon electrode modified with carbon-encapsulated copper nanoparticles was prepared as working electrode.The electrochemical behavior of p-nitrophenol was tested by cyclic voltammetry in alkaline solution.Compared with the bare glassy carbon electrode,the modified electrode exhibited excellent electrocatalytic activity for the degradation of p-nitrophenol,and increased peak current.The influencing factors,such as scanning rate,solution concentration and so on,were discussed.
