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 Ni-Cr wires (i.e. heat element; 0.5 mm in diameter) by means of electrophoretic deposition. The present “heater-built-in” system with TiO2 is found to possess an excellent decomposition ability of toluene into H2O and CO2. This enables us to realize a compact, practical device with low cost.
