Abstract
The immobilization technique is important to extend the application field of a photocatalyst. The titanium plate surface was changed into a TiO2 thin film by the anodizing process. The anodized photocatalyst reactivity increased with relative humidity, but excessive humidity led to a decrease of the reaction rate. Production of CO2 is fully indicative of the oxidation process that was shown to prevail in different organic compounds examined. The electrochemical effect enhanced the decomposition rate of the organic compounds, but excessive applied voltage decreased the reaction rate. In a comparative study of the sol-gel coated versus anodized TiO2, the anodized TiO2 in the presence of the anodic potential discharge showed much better decomposition rate than the sol-gel coated TiO2.
