This study focused on toluene photodecomposition in a presence of H2O over metals (Ba, Al, Si, V, and W)-incorporated TiO2. The nanometer-sized metal-TiO2s, including Ba2+, Al3+, Si4+, V5+, and W6+ ions, were prepared using a solvothermal method. The toluene (100 ppm) photodecomposition in continuous system increased in the order of Al-TiO2＞Si-TiO2＞pure TiO2＞W-TiO2＞Ba-TiO2＞V-TiO2, and the maximum toluene conversion was 45% in Al-TiO2 film after 120 min. The toluene conversion remarkably increased, however, in all photocatalysts with H2O addition during the toluene photo-decomposed reaction, and in particular, the conversion reached up to 90% after 120 min in Al-TiO2 and Si-TiO2 with more hydrophilicity. |
