摘要：

Mesoporous hollow nanospheres have attracted much attention due to their potential applications in the fields of catalysis and drug release. Recently, various hollow silica nanospheres with mesopores in the walls have been prepared through templating approaches. However, the effect of silica precursors on the hollow structure has not been well studied. Herein, mesoporous silica hollow nanospheres were prepared through a chiral amphiphile/organic solvent dual-templating approach. The silica nanostructures are controllable by manipulating the amount of the silica precursors. A diffusion-polycondensation mechanism was proposed to drive the formation of the hollow spheres.
