分る。The following can be said from FIG. 8, FIG. 9 and FIG. First, in the presence of ultraviolet light, anatase-type TiO 2 exerts a catalytic action. Second, the catalysis is 70
It shows the maximum value around 0 ° C, and the odor removal rate after 30 minutes is 50
% Or more, it is necessary to be 300 ° C. or more and less than 900 ° C. This is presumably because the activity is unlikely to occur when the heat treatment temperature is lower than 300 ° C, and the structure of TiO 2 changes from anatase to rutile when the heat treatment temperature exceeds 900 ° C. Third, it is understood that anatase having a small particle size is preferable for the catalytic action.
