PCT No. PCT/JP95/02749 Sec. 371 Date Jul. 7, 1997 Sec. 102(e) Date Jul. 7, 1997 PCT Filed Dec. 27, 1995 PCT Pub. No. WO96/20786 PCT Pub. Date Jul. 11, 1996A catalyst of the present invention is adapted for purifying fumigation exhaust gases, and comprises, as a catalyst component A, a metal oxide containing at least one, or a composite oxide containing two or more metals selected from the group consisting of Ti, Si and Zr; and, as a catalyst component B, an oxide containing at least one selected from the group consisting of V, Cu, W and Cr; and has an average micropore diameter in the range of 0.010 to 0.070 mu m, a total micropore volume in the range of 0.30 to 0.60 ml/g, and a specific surface area in the range of 50 to 200 m2/g. The use of this catalyst makes it possible to economically and efficiently purify fumigation exhaust gas.
