Synthesis of hollow and rattle-type mesoporous silica spheres by treating layered mesoporous silica with a basic solution, and using the spheres as microreactors for two-phase reactionsElectronic supplementary information (ESI) available: Dissolution rate time courses; SEM and TEM images of the hollow spheres; pore and particle size distributions of the hollow spheres; a schematic of the halogen exchange reaction; the effects of the agitation speed and the amount of hollow spheres added on the h
Hollow silica spheres with radially oriented mesopores were synthesized by treating core-shell structured mesoporous silica spheres (pure silica core and propyl group-grafted silica shell) with an ammonia solution in the presence of alkyltrimethylammonium chloride. The pure silica cores dissolved in...
