| Abstract: | TiO 2 photoelectrocatalysis is a kind of photocatalytic oxidation technologies assisted with electrochemical method. Photogenerated electrons can be removed from TiO 2 electrodes before they could recombine with the holes by the application of a suitable external bias potential, so the quantum efficiencies can be improved and the organic pollutants mineralized completely. The principle and mechanism of photoelectrocatalysis on TiO 2, the recent research progress and the key problems for the scale up, design and modeling of this kind of reactors were reviewed, and some research topics in this respect and methodology were also recommended. |
