Silver nanoparticles growth in a mesoporous silica film templated with the F127 triblock copolymer

The elaboration of mesoporous silica films supporting silver nanoparticles is described. Mesoporous silica films were infiltrated with silver salt solutions of different concentrations and chemical reduction treatment was performed in situ by NaBH4. The films have been characterized by TEM, AFM, XRD, and UV–vis spectroscopy. Homogeneous distributions of silver nanoparticles have been obtained by this method.
