<P>PROBLEM TO BE SOLVED: To provide a deodorizer capable of enhancing decomposition and removal efficiencies of odorous gas components or toxic volatile chemical substances in air by a small amount of a noble metal-based catalyst and charged electric power, and cleaning the air more inexpensively with lower energy. <P>SOLUTION: This device is provided with a discharge electrode 1 applied with a high voltage and a grounding electrode 4 disposed in a flow space of treating object fluid; and a catalyst part 2 disposed between the discharge electrode 1 and grounding electrode 4 and cleaning the odorous gas components and toxic volatile chemical substances. The catalyst part 2 carries a mixture formed by mixing one or more kinds of porous adsorbent having mesopores or micropores, such as zeolite, activated carbon or silica gel; a porous metal oxide having fine pore structure consisting of mainly transit metal, such as manganese oxide or titanium oxide; and noble metals like platinum or palladium. <P>COPYRIGHT: (C)2007,JPO&INPIT |
