The inventors have discovered that using Kaolin, a low-cost aluminosilicate clay mineral, it is possible to synthesize nanoporous materials with micropores and/or mesopores using a micropore template and/or an organosilane as a mesopore template. Mesoporous and microporous materials synthesized by the invention have advantages, as compared with conventional synthesis, in that it is possible to synthesize microporous aluminophosphates and aluminosilicate molecular sieves as well mesoporous aluminosilicates and aluminophosphates which are hierarchically structured and have a well-crystalline microporous wall structure. Nanoporous material of the present invention is expected to be more cost-effective for application in separation and catalytic reaction of macromolecules of different dimensions as well as in the catalytic processes of petroleum, including heavy oil and residue and bulky biomass-derived molecules.
