Paper Title:
Dynamics Study of TiO2 Semiconductor Photoelectrode by EIS in the Ammonia Degradation
  Abstract

The photoelectrocatalytic activation and semiconductor character parameter have been investigated by the electrochemical impedance spectroscopy (EIS) and Mott-Schottky test on the Ti/TiO2 photoanode in ammonia system. Based on the evolution of electrical parameters of the equivalent circuit, the most probable dynamics has been stated that the redox reaction in the Ti/TiO2 film photoanode interface is the main rate-determining step. According to the products analysis, the reaction mechanism of ammonia degradation by TiO2 has been presented.
