title: Photoelectrocatalytic degradation of recalcitrant organic pollutants using TiO2 film electrodes: an overview.
abstract: Photoelectrocatalytic (PEC) technology involved applying an electrical bias to a TiO(2) film electrode, has been widely applied to the degradation of refractory organic pollutants, owing to its high degradation efficiency. This paper reviews recent developments in the PEC degradation of recalcitrant organic contaminants using a TiO(2) film electrode. The preparation and application of various TiO(2) film electrodes have been investigated, as well as the parameters that influence PEC activity such as the crystal structure, the film thickness and substrate material, the applied electrical bias, the solution pH and conductivity. The improvement of PEC activity by doping the TiO(2) film electrode with metal and non-metal ions has been discussed. The mechanism and kinetics for the PEC degradation of organic pollutants have also been highlighted.
