Abstract
The present invention relates to photochemical catalyst preparation and application fields, it is desirable to provide a kind of zeolite molecular sieve supports the preparation method and applications of ferrum-based catalyst.Include: to be dispersed in water zeolite molecular sieve, add source of iron, is carried out ion exchange 6~24 hours under 80 DEG C and stirring condition；Reaction product is taken out, washing, drying are placed in Muffle furnace, roast 4~10 hours under the conditions of 400~600 DEG C, obtain zeolite molecular sieve and support ferrum-based catalyst.The cost of material used in preparation process of the present invention is lower, preparation process is simple.In the immobilized photochemical catalyst of gained zeolite, iron particle is dispersed on zeolite molecular sieve, and the content of iron is controllable, and mass fraction is adjustable within the scope of 0.1-99%, and molecular sieve pore passage structure is also adjustable, can select suitable cellular structure according to intermediate.Gained catalyst hydrocarbon oxidation application in, to reaction condition require it is not stringent, only using oxygen as oxygen source room temperature under can realize reaction, also very high conversion ratio and selectivity.
