ODOR REMOVAL CATALYST AND USE THEREFOR

An object of the present invention is to provide a deodorizing catalyst capable of rapidly adsorbing and removing an odor in a space such as the inside of an automobile, continuously reducing the odor for a long period of time by decomposing the adsorbed odor component, and preventing the odor from returning, and to provide a deodorant composition and a deodorizing product using the deodorizing catalyst.The deodorizing catalyst of the present invention is a deodorizing catalyst containing a composite oxide and a metal component containing Pt supported on the composite oxide, and having a degree of reduction represented by the following formula (1) in a range of 60% to 86%: degreeofreduction%=100−X/Y×100 (in the formula (1), X represents a peak area obtained from a thermal conductivity detector (TCD) when the catalyst is dried and reduced by heating from 40°C to 400°C, and Y represents a peak area obtained from the TCD when an oxidation catalyst obtained by heat-treating the catalyst in an air or under oxygen atmosphere at 150°C for 2 hours and then cooling the catalyst to 40°C or lower is reduced by heating from 40°C to 400°C).
