PURPOSE:To prevent the deterioration of the ozone decomposing ability of a catalyst under severe conditions by using the oxides of one or more kinds of metals selected among V, Mo, Zr, Sn, Nb and W and Ti oxide as the principal components of the catalyst. CONSTITUTION:A catalyst for decomposition of ozone contg. the oxides of one or more kinds of metals selected among V, Mo, Zr, Sn, Nb and W and Ti oxide as the principal components is produced by impregnation, kneading, coprecipitation, precipitation, mixing or other means. The catalyst may be a binary catalyst such as V2O5-TiO2 or MoO3-TiO2 or a ternary catalyst such as MnO2-V2O5-TiO2 or MnO2MoO3-TiO2. The pref. amt. of the oxides of one or more kinds of metals selected among V, Mo, Zr, Sn, Nb and W is about 5-75wt.% (expressed in terms of the metals) and that of the Ti oxide is about 25-95wt.% (expressed in terms of Ti). |
