摘要

In the present invention, the oxidation for being disclosed a kind of catalyst intends the concentration of total volatile organism theres are 100 to 10 000 milligrams/ME3 air is wherein aoxidized, and contains active component and component change surface nature and its manufacturing method in 60 to 500 degC of temperature and the wherein catalyst. The oxide of the catalyst activity component is that the transition metal of representative is selected from or mixtures thereof cobalt, copper, nickel, chromium, manganese or iron, is the magnesium dioxide mixture magnesium dioxide and aluminium oxide of representative with above-mentioned catalyst surface property modifying component. The transient state metal oxide of amount like this or the range of mixture 10 to 90 weight percent amounts catalyst surface property modifying component range in 10 to 90 weight percent. The catalyst preparation of the invention, to make the solution transition metal salt of the transition metal salt of aqueous solution or the mixture of water, the aqueous solution of aqueous solution titanium dioxide magnesium salts and optional oxidation aluminium salt vulnerable to the alkali carbonate and/or bicarbonate and/or alkali metal hydroxide being deposited in alkaline aqueous solution range from 5 to 100 the pH value of degC and reaction mixture 8 to 13. By obtained suspension then contracting contract to it is mature be 5 to 180 degC up to 48 time ranges, obtained solid product is then filtered out from suspension, washs, is dried, form, by calcining, in temperature from 200 to 800 degC.
