ZnO and TiO 2 nanoparticles encapsulated in boron nitride nanocages

Abstract

ZnO and TiO 2 nanoparticles encapsulated within boron nitride nanocages were produced by a sol–gel method and thermal annealing treatment. The structural and chemical characterizations of these nanoparticles were performed with the use of high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD) and FTIR. The size of ZnO and TiO 2 nanoparticles encapsulated within BN nanocages was determined by analysis of the X-ray diffraction peaks according to the Debye–Scherrer equation.
