STUDY ON THE MODIFICATION OF SEMICONDUCTOR PHOTOELECTRODE BY PLASMA POLYMERIZATION——POLYACRYLONITRILE/n-GaAs, n-GaP ELECTRODES
Abstract:
Polyacrylonitrile (PAN) film attached to n-GaAs, n-GaP photoelectrode surface by plasma polymerization has been studied. Both electrochemical behaviors and stability of the modified electrodes have been investigated. The results showed that the semiconductor electrodes with PAN film decreased photocorrosion in a certain degree, and their electrochemical characteristics and stability were improved remarkably after plasma doping.
Cyclic voltammetric analysis demonstrated that the redox reaction occurred in I-PAN films could be carried out rapidly on electrode surfaces, in favor of the capture and transfer of photoinduced holes by the films to redox couples in solution.
