| Abstract: | TiO2 thin membrane photoelectrode prepared adopting sol-gel method was used as the working electrode with Pt wire as the counter electrode, and saturated calomel electrode as the reference electrode to study the photoelectrocatalytic degradation of 10-nonylphenol ethoxylates. This working electrode possessed characteristic behavior of n type semiconductor. Under the condition of external bias potential 0.6V pH=5 and H2O2 of 30mg/L and 4h irradiation, the rate of degradation of nonylphenol ethoxylates solution of 50mg/L initial reached 53.26%. The influence of the factors of oxygen existence external bias potential and pH value on photoelectrocatalysis reaction was discussed. |
