“…Especially, TiO 2 has attracted as a photoconductor for direct digital color proofing system. 1) Nowadays, it has attracted attention as a material for photocatalyzers 2) and solar cells. 3,4) We have previously shown, for the first time, that polycarbonate (PC) used as a material for optical discs can completely be decomposed in the presence of TiO 2 powders, releasing a huge amount of exothermic energy of about 1.85 kJ/g.…”

We are so far involved in complete decomposition of organic wastes as well as volatile organic compounds (VOC) by the use of thermally generated holes in TiO 2 . In view of the practical use of the present system, fixation of TiO 2 powders onto a substrate seems to be the core technology. To realize this, we have tried in the present investigation to fix powdered TiO 2 onto SUS meshes or Ni-Cr wires by means of electrophoretic deposition. We have constructed two kinds of equipment. One is a cartridge system which includes ten pieces of the mesh disk coated with TiO 2 that are arranged vertically. The other is a ''heater-built-in'' system with a triple-coaxial structure equipped with Ni-Cr/Cr 2 O 3 / TiO 2 wires. The former is used in combination with an external furnace; whereas the latter is a stand-alone system. Both systems exhibit excellent performance to completely decompose VOC into H 2 O and CO 2 .

Previously involved in complete decomposition (H 2 O + CO 2) of organic wastes (mainly thermoplastic and thermosetting polymers), as well as exhaust of diesel engines by the use of thermally generated holes in TiO 2 at about 350-500°C under sufficient O 2. Then, we struck on an idea that H 2 can be produced in place of H 2 O under O 2-deficient conditions. Because of this, an attempt has been made in the present investigation to produce hydrogen from methanol or methane. Hydrogen is found to be successfully produced from methanol at 350-400°C under 5-20% O 2 , or from methane at 450-500°C under 50% O 2. The conversion efficiency amounts to about 70-85% for methanol while about 40% for methane.
