PURPOSE:To allow the decomposition reaction of a malodor with a photo- catalyst to proceed efficiently by corrugating the photocatalyst supporting a semiconductor, introducing gas contg. the malodor and irradiating the photocatalyst with UV. CONSTITUTION:Alumina-silica ceramic paper is corrugated at a specified height of corrugation and a specified pitch and a titania sol is impregnated into the corrugated paper, dried and heat-treated to support titanium oxide. The resulting photocatalyst 1 is set on the bottom of a reactor and air contg. a malodor is discharged from a cylinder. A UV lamp 3 is then lighted to irradiate the photocatalyst with UV. Since the photocatalyst is corrugated, a turbulent flow is generated to increase the efficiency of contact of the photocatalyst with the gas and the amt. of the photocatalyst irradiated with UV is increased even in a narrow space. |
