研究了碳化TiO2-木质复合材料对甲醛吸附的光催化机理。为此，研究了氧和/或水的存在对复合材料光催化活性的影响。结果表明，碳化tio2 -木质复合材料的光催化作用需要水将甲醛分解成二氧化碳。然而，氧气对其分解并不是必需的。基于这一要求，探讨了TiO2微晶对碳化TiO2-木质复合材料中甲醛吸附的光催化机理。
The photo-catalytic mechanism of the TiO2 crystallites was studied for formaldehyde adsorbed in the carbonized TiO2-woody composites. To do so, the effects of the presence of oxygen and/or water were investigated on photo-catalytic activities of the composites. As a result, it became clear that photo-catalysis of the carbonized TiO2-woody composites requires water to decompose formaldehyde into CO2. However, the oxygen is not essential for its decomposition. Based on this requirement, the photo-catalytic mechanism of the TiO2 crystallites was discussed for adsorbed formaldehyde in the carbonized TiO2-woody composites.
