Preparation and Characterization of BCN–TiO₂ Nanoparticles

Abstract

BCN–TiO2 was prepared by doping Ti(OH)4 with graphite-like structure BCN in an annealing process at 400[°C] for 2[h]. The catalyst samples were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and scanning electron microscope (SEM). Graphite-like structure BCN was detected by XRD. The results showed that with graphite-like structure BCN doped in, the crystal size became smaller than pure TiO2. Also B, C, N were detected in crystal lattice of TiO2, in which Boron was in the form of Bx+, Carbon substituted some of the lattice oxygen atoms as Ti-C, and Nitrogen was in the form of Ti-N and Ti-O-N.
