| Popis: |
A simple and non-toxic way was employed to fabricate electrical conductive TiO2materials based on a chemical reduction process here. Glucose was selected as a reductant to reduce AgNO3to obtain Ag-modified TiO2nanoparticles. The properties of the nanoparticles were characterized by XRD, TEM, and fourpoint probe resistivity meter. The results show that the TiO2was successfully modified by Ag nanoparticles, and the major crystalline phase of TiO2in the Ag-modified TiO2composite is anatase phase. The size of Ag increased with the AgNO3concentration increasing. Compared with pure TiO2, the Ag modified TiO2has a higher electrically conductive. In principle, it is expected to be a general and versatile approach to increase the conductivity of insulator or semiconductor. |
