In this work a new approach has been developed for the synthesis of SiO2@Y2O3 particles with core–shellstructure. The method is based on the synthesis of a covalently bonded sacrificial polymer shell grown ontosilica particles. It is suitable to promote and stabilize the adsorption of different ions, namely Yttrium from itsnitrate solution. After calcination and consequent elimination of the sacrificial polymer shell, the SiO2@Y2O3core–shell particles are obtained. Results reveal that the shell thickness of these core–shell particles is higherand more uniform than that of particles prepared without sacrificial polymer shell.

Abstract

In this work a new approach has been developed for the synthesis of SiO2@Y2O3 particles with core–shellstructure. The method is based on the synthesis of a covalently bonded sacrificial polymer shell grown ontosilica particles. It is suitable to promote and stabilize the adsorption of different ions, namely Yttrium from itsnitrate solution. After calcination and consequent elimination of the sacrificial polymer shell, the SiO2@Y2O3core–shell particles are obtained. Results reveal that the shell thickness of these core–shell particles is higherand more uniform than that of particles prepared without sacrificial polymer shell.
