Photoelectrocatalytic Properties of Electro Exploded TiO2 Nanopowder in Oxalic Acid Degradation

In this work. the photocatalytically active thin TiO₂ films were produced by deposition of TiO₂ by electrophoresis onto a transparent conducting electrode substrate. In order to avoid the filtration step of suspended particles after water treatment, TiO₂ can be immobilized onto inert support material (Mills et al., 1999). The SnO₂ or ITO (indium and tin oxides) - coated glass plate we used as a conducting support. The thin films were used to study the photoelectrochemical degradation of oxalic acid under near UV light irradiation. Degradation was monitored as CO₂ formation accounted for up to 100% of the total organic carbon degradation for medium starting concentration. Incident-photo-to-current conversion efficiency, quantum yield as well as Faradaic efficiencies were calculated for the degradation experiment.
