In this paper, a novel protein templating approach to synthesize macroporous materials has been demonstrated. Sponge like architectured macroporous oxides(silica, titania) have been firstly synthesized by using low cost commercial egg white protein as the template. The pore size of the three dimensional macroporous materials can be tuned from 50 to 400 nm by adding different surfactant. The morphology and the channel of the macroporous materials can also be controlled by the surfactant. The formation of macroporous material is resulted from the phase separation between the protein and inorganic sol.
In this paper,we have reported the sy nthesis of highly-ordered mesoporo us material with domestic AucP as templating agent.The product has a BET surface area of 534.8m 2 ·g -1 ,pore size of 4.6nm and pore volume of0.68cm 3 ·g -1 .The synthesis cost of FDU-7is much l ower than that of SBA-15(just 25%of SBA-15),which will be much helpful to the industrializa tion of such mesoporous materials.
A\} new highly ordered mesostructured silica(possible space group \%Fm3m\%) was synthesized by \{using\} tri\|headgroup quaternary ammonium surfactant \{CH\-3(CH\-2)\-\{17\}N\++(CH\-3)\-2CH\-2CH\-2N\++(CH\-3)\-2CH\-2CH\-2\}CH\-2N\++(CH\-3)\-3\53Br\+-(C\-\{18\|2\|3\|1\}) under a basic condition. The cubic mesoporous silica product has an \{average\} pore size of 2.9 nm, a large BET specific surface area of 991 m\+2/g and a large pore volume of \{0.98 cm\+3/g\}.
