The present invention relates to a kind of bi-component composite alumina high heat stability ordered mesoporous materials, it is that organic carboxyl acid, inorganic acid and block copolymer nonionic surfactant are dissolved in the dehydrated alcohol containing deionized water, silicon source stirring and dissolving is added, under open state after solvent flashing, it is added in metal heteroatom precursor solution, it seals solvent heat grafting under high pressure to handle, product roasts to obtain two-component composite alumina high heat stability ordered mesoporous material after processing.Mesoporous material prepared by the present invention has high-specific surface area and pore volume, structure-controllable, thermal stability height, hole wall acidity and hetero atom active component adjustable, and meso-hole structure high-sequential. |
