Titanium dioxide was once extensively investigated as a photoconductor for the electrophotographic photoreceptor early on. We are so far involved in complete decomposition of organic wastes as well as volatile organic compounds (VOC) by thermally generated holes in TiO2. In view of the practical use of the present system, fixation of TiO2 powders onto a substrate seems to be the core technology. To realize this, we have tried in the present investigation to fix powdered TiO2 onto metal meshes by means of electrophoretic deposition. We have constructed a cartridge which includes ten pieces of mesh disk (25 mm in diameter coated with TiO2) that are arranged vertically. The present system in combination with an external furnace is found to exhibit an excellent performance to completely decompose VOC into H2O and CO2 with a high rate.
