英文摘要 | sulfates have big influence on the structure and morphology of the mesoporous silicas synthesized under weak acidic conditions. the evolution from silica hollow nanospheres to doughnut-like nanoparticles, and to fdu-12 type mesoporous silicas with fm (3) over bar m symmetry can be induced by cuso(4) during the condensation of tmos around pluronic f127 surfactant in weak acidic solution (ph = 3.25). it is noteworthy that doughnut-like nanoparticles can be obtained in the presence of lower amounts of cuso(4). similar to cuso(4), other divalent sulfates, such as znso(4), niso(4), and mgso(4) can also induce the formation of fm (3) over bar m mesostructure. however, the presence of k(2)so(4) and na(2)so(4) specially results in the formation of hollow nanospheres. plausible mechanisms for the formation of fdu-12 and hollow nanospheres were also proposed.
