Conductive Silver-Modified TiO₂ Nanoparticles Prepared by a Silver Mirror Reaction

Abstract:

A simple and non-toxic way was employed to fabricate electrical conductive TiO₂ materials based on a chemical reduction process here. Glucose was selected as a reductant to reduce AgNO₃ to obtain Ag-modified TiO₂ nanoparticles. The properties of the nanoparticles were characterized by XRD, TEM, and fourpoint probe resistivity meter. The results show that the TiO₂ was successfully modified by Ag nanoparticles, and the major crystalline phase of TiO₂ in the Ag-modified TiO₂ composite is anatase phase. The size of Ag increased with the AgNO₃concentration increasing. Compared with pure TiO₂, the Ag modified TiO₂ has a higher electrically conductive. In principle, it is expected to be a general and versatile approach to increase the conductivity of insulator or semiconductor.
