Abstract

Achieving particle size control and pore size control is crucial when utilizing mesoporous silica to perform fundamental studies. Pore size can be controlled by adjusting the reaction condition during the synthesis of mesoporous silica. Here realizing that different sizes of particles fall at different speeds in the liquid, we achieve a narrow particle size selection through the sediment of the mesoporous silica in water. By applying particle size selection on mesoporous silica with different pore sizes, silica particles with the exact pore sizes but different particle sizes, or with varying sizes of pore but exact particle sizes are obtained.
