Zusammenfassung: | The invention discloses a preparation method and application of an iron and cerium loaded meso-porous silicon-based catalyst, and belongs to the field of catalyst preparation and application. Firstly,a meso-porous silicon material is prepared; secondly, the meso-porous silicon material and a cerium precursor are mixed; after filtering and drying, roasting is performed; finally, the powder obtained after the roasting is mixed with an iron precursor; after the filtering and drying, roasting is performed to obtain the iron and cerium loaded meso-porous silicon-based catalyst. The preparation method is simple; the prepared catalyst has the advantages that the removal efficiency is high; the removal capability is high when being used for catalytic oxidation of low-concentration formaldehyde inmixed gas at the normal temperature and the normal pressure.
