Abstract

See full text

The present invention relates to a method of preparing a spherical mesoporous silica structure containing silver nanoparticles dispersed therein by adding a silver nitrate solution to an aqueous surfactant solution and performing a sol-gel process and to spherical mesoporous silica prepared thereby. The spherical mesoporous silica is cost-effective compared to a conventional method that uses silver nanoparticles as a raw material, because the silver nitrate solution that is inexpensive compared to silver nanoparticles is used. Also, the spherical mesoporous silica can be with high productivity in large amounts, and thus is easily commercialized. Moreover, because silver nanoparticles are incorporated into the pores of the mesoporous silica, the silver nanoparticles are used stably and do not change color and odor. In addition, the spherical mesoporous silica exhibits various additional effects, including far-infrared ray emission and deodorization, attributable to silica.
