摘要：

An approach has been developed for the wet synthesis of mesoporous silica shell on the surface of various spherical composite particles with different zeta potential. It is demonstrated that the surface charge of the core particles influences the porous structure of the obtained shell. The proposed method allows obtaining a uniform layer of the same thickness on the surface of each core particle preventing their coalescence.
