Preparation of silica-silver heterogeneous nanocomposite by novel method using polyol process

초록

Silica-Silver heterogeneous nanocomposite was successfully prepared by polyol process for the first time. Silver nanoparticles are homogeneously immobilized onto the silica surface using thiol groups as a chemical protocol. The morphology of the composite materials was observed by TEM and FE-SEM. Also, the optical properties of resulting particles were investigated by UV-vis spectrophotometer. The formation mechanism of composite materials was discussed briefly. This novel method can be extended to the preparation of other nanocomposites. Based on this novel route, the more detailed studies about the preparation of heterogeneous nanocomposite are in progress.
