- 論文の詳細を見る
An effort was made to develop carbonized TiO_2-woody composites which can effectively remove and decompose harmful air pollutants in environments. As an example of an air pollutant, formaldehyde(HCHO)was selected for evaluating the carbonized TiO_2-woody composites. The composites were composed of carbonized wood as an adsorbent and the anatase-form of titanium dioxide(TiO_2)as a photo-catalyst. They showed a much higher decomposing ability toward formaldehyde, when compared with the performance of non-composite controls composed of a simple physical mixture of carbonized wood and TiO_2 granules. This indicates that synergetic effects existed in the carbonized TiO_2-woody composites for photo-catalytic environmental cleaning. The topochemical mechanism inducing such synergetic effects is discussed in relation to the distribution of TiO_2 granules in the composites.
