Nickel oxide and nickel co-doped graphitic carbon nitride (NiONiGCN) nanocomposites were successfully prepared by thermal treatment of melamine and NiCl(2)6H(2)O. NiONiGCN nanocomposites showed superior electrochemical catalytic activity for the oxidation of octylphenol to pure GCN. A detection method of octylphenol in environmental water samples was developed based at NiONiGCN nanocomposites modified electrode under infrared light irradiation. Differential pulse voltammetry was used as the analytic technique of octylphenol, exhibiting stable and specific concentration-dependent oxidation signal in the presence of octylphenol in the range of 10nM to 1 mu M and 1 mu M to 50 mu M, with a detection limit of 3.3nM (3S/N).
