Abstract

Complete decomposition of organic wastes using thermally-generated holes in titanium dioxide at high temperatures has been investigated. In view of the practical use of the present systems, fixation of TiO2 particles on substrates seems to be the core technology. To realize this, we have investigated direct oxidation of Ti or Sn-coated Al2O3 balls in order to prepare thin layers of TiO2 or SnO2 on the Al2O3 surface, respectively. Formation of TiO2 of the rutile phase or SnO2 has been identified by Raman spectra. In addition, complete decomposition of toluene (as an example of volatile organic compounds) has also been confirmed by the TiO2 or SnO2-coated Al2O3 balls at about 500°C.
