Abstract

Pure macroporous silica matrix using a template of polystyrene (PS) was prepared by the sol-gel method. Macroporous Ag-$SiO_2$ composite materials, which were homogeneously dispersed with Ag particles in the macropores, were successfully fabricated. The pure porous silica had ordered pore sizes of 100 nm and 200 nm, which was adjusted under consideration of the template size. The macroporous Ag-$SiO_2$ composite showed the ideal ordered distribution of the pore in case of the adding of 3 wt% $AgNO_3$ under consideration of controlling of the pore size as well as microstructural observation of $AgNO_3$concentration. The macroporous Ag-$SiO_2$ composites had ordered 100 nm and 200 nm pores, and the Ag particles within the matrix showed the size of 15~20 nm.
