Abstract
- Graphene is the most attractive carbon-based material at present and attracting increasing attention as promising candidates for applications in numerous areas, because of its extraordinary chemical, thermal and mechanical properties. In this paper, we discussed an innovative and simple method to synthesize titanium dioxide (TiO 2 ) nanoclusters, using graphene as a mid-step template not as a component of final product. Using this method, the graphene was firstly fully coated with TiO 2 nanoparticles by the thermal decomposition of titanium (IV) isopropoxide in a supercritical carbon dioxide (SC-CO 2 ) at 200 °C; the developed TiO 2 /graphene composites then were heated in an oxygen atmosphere. Eventually the TiO 2 nanoclusters were obtained. The prepared TiO 2 nanoclusters showed irregular features with high surface coverage, providing promises in a wide range of applications, especially for photo-degradation of organic compounds in aqueous solution under the radiation of UV-light.
