Photoelectrocatalytic Oxidation of Methyl Orange in KHCO3 Solution

Article Preview

Abstract:

Photoelectrocatalytic oxidation of methyl orange on TiO2 films were investigated in KHCO3 solution. Electro-degradation alone could degrade little methyl orange in the solution. The film electrode prepared using PEG had less activity than the film without PEG. In the potential range from 0 to 1.3 V, degradation rate on film without PEG increased slowly until a sharp increase at potential of 1.2 V. Electrolyte concentration in the solution is not a key factor influencing degradation activity since the total potential was not high. With increasing reaction time, degradation rates on the two film electrodes increased at the same time, while the electrode prepared without PEG performed better than the electrode prepared with PEG.
