Synthesis and Assembly of Core/Shell Nanospheres

Abstract

In this paper, we reported a new simple and effective method, osmotic membrane-assisted self-assembly, for fabricating massive interconnected macroporous silica monolith as catalyst supports. Using the method, we can prepare massive interconnected macroporous silica monolith with homogeneous structures beyond millimeter scale one time. Typically, silica/polystyrene and polystyrene/poly 4-vinyl pyridine core/shell latex spheres with different surface and composition have been prepared, and were used as templates to fabricate massive macroporous monolith with different structure. We believe the advantages of this method will provide the possibilities for fabricating various macroporous catalyst supports.
