Synthesis of Biphasic Defective TiO2–x/Reduced Graphene Oxide Nanocomposites with Highly Enhanced Photocatalytic Activity

  • Published:
Chemical Research in Chinese Universities Aims and scope

Abstract

Biphasic defective TiO2–x/reduced graphene oxide(RGO) nanocomposites were synthesized by simple hydrothermal reactions. Compared with TiO2–x and commercial P25, TiO2–x/RGO shows much better photocatalytic activity and excellent stability in pollutants degradation, which could be ascribed to Ti3+ centers complexed with RGO and the synergetic effect between the two phases. The study reveals a new route for the synthesis of mixed-phase defective TiO2–x/carbon material nanocomposites for photocatalytic applications.
