The invention belongs to the technical field of
nano porous materials, in particular to a resol-assisted synthetic
large aperture ordered mesopore metallic
oxide material and a preparation method of the material. According to the material and the preparation method thereof, an amphiphilic block
copolymer (PEO-b-PS and PEO-b-PMMA) with
large molecular weight hydrophobic segments is taken as a template agent, the principle of assisted self-
assembly of resol is utilized, and in a
solvent evaporation process, the resol fixes a
metal precursor to a hydrophilic end of the template agent, the self-
assembly is induced through
solvent evaporation, so as to enable the template agent and a
mesoporous material precursor to react to form microphase separation, and obtain an ordered mesostructure; after using
large molecular weight hydrophobic block to form a large hydrophobic area, and removing the template agent, the
large aperture ordered mesopore metallic
oxide material is obtained. The synthetic
mesoporous material has a super
large aperture, the shape of the pore channel of the material is spherical, the mesoporous of the material is orderly arranged, and the material has a bimodal mesoporous structure and a super high specific surface area; the method is simple, the
raw material is easy to obtain and the material is suitable for enlarged production.
