Titanium(IV) oxide (TiO_2) fine particles were filled in paper and the photocatalytic activity for organic gases was measured on the sheet. The filling paper had TiO_2 up to 34 wt% in it and was changed the surface smoothness by a machine calendar. When light of ultraviolet-ray irradiated the sheets in a reaction chamber, concentration of C_2H_4, HCHO, CH_3CHO or C_6H_6 was measured for hours. TiO_2 filling papers were confirmed to have a good activity. It was confirmed that the reaction activity and the catalyst life of the filling paper were improved by the surface smoothness. And, it was found on the filling paper that hydrophobic C_2H_4 reactivity decreased with an increase of humidity, but that hvdroohilic CH_3CHO's didn't.
