A facile hydrothermal approach for construction of carbon coating on TiO _2 nanoparticles

摘要

Herein a facile hydrothermal approach is used to construct carbon coated TiO _2 nanoparticles employing dextrose as the source of carbon. The procedure is operated at a low temperature of 200 °C. Fourier infrared spectroscopy demonstrated the successful coating of carbon on TiO _2 nanoparticles. The phase composition of TiO _2 and carbon coated TiO _2 nanoparticles were studied using X-ray diffraction and the surface morphology was analyzed by scanning and transmission electron microscopy. The existence of carbon coating on TiO _2 nanoparticles was revealed by thermogravimetric analysis through different thermograms exhibited for TiO _2 and carbon coated TiO _2 nanoparticles. The reported method offers a simple and efficient approach for production of carbon coated TiO _2 nanoparticles.
