PROBLEM TO BE SOLVED: To provide a composite functional material capable of detoxifying harmful components such as nitrogen oxide, an organochlorine compd. and the like in combustion exhaust gas by using a catalyst. SOLUTION: A powdery catalyst with a mean particle size of 20-80 μm consisting of vanadium pentoxide and tungsten trioxide is carried on a nonwoven fabric comprising ceramic fibers 1 in an amt. of 15±10 wt.% per the total weight of the nonwoven fabric in a dispersed state to form a gas permeable body 4 being a composite functional material wherein combustion exhaust gas containing harmful components such as nitrogen oxide, an organochlorine compd. and the like is passed through the gas permeable body 4 to decompose and detoxify nitorgen oxide, the organochlorine compd. and the like. |
