1. a kind of method that direct thermal decomposition method prepares high specific surface area and mesoporous composite oxide of metal, it is characterised in that by such asLower step is implemented:



  • a)

    Metal salt is weighed, powder is fully ground into;

    Structure directing agent is weighed again, is fully ground into powder;



    b)

    Metal salt and directed agents are well mixed according to certain mol proportion, and grind abundant, mixture is obtained;



    c)

    Mixture is laid in porcelain boat and is placed in Muffle furnace, in air atmosphere, with 1 DEG C/min of heating rate,It is heated to 110~130 DEG C and is kept for 2~3 hours, is further continued for being heated to 400~700 DEG C, and kept for 3~4 hours, natural coolingAfter obtain precursor samples;



    d)

    Precursor samples are washed three times respectively with deionized water and absolute ethyl alcohol, then dried, target product is obtained.
