Photoelectrocatalytic Degradation of Methyl Orange on Porous Ti02 Film Electrode in NaCl Solution

摘要：

Porous Ti02 films and smooth Ti02 films were fabricated by sOl-gel dip-coating technique using titanium plate as support substrate．Photoelectrocatalytic(PEC)degradation of methyl orange was investigated in aqueous NaCl solution using the TiO2 films．PEC degradation efficiencies showed strong dependence on the concentrations of aqueous NaCl solutions and applied potentials．Photoelectrocatalytic activity of the porous Ti02 film was higher than that of the smooth Ti02 film at lower applied potential．95．2％ decolorization Of the dye could be achieved in 50 minutes at applied potential of 0.6 V in 0.05 M NaCl solution on porous Ti02 films，while the efficiency was only 79.9％on smooth Ti02 films．Electrodegradation(ED)of these two film electrodes almost had no effeCt on methyl orange．Photocataiytic oxidation(PCO) degradation was 36.4％for the porous TiO2 thin film after 80 min，and 32.6％for the smooth Ti02 thin film during the same condition．
