Abstract
Nitrogen-doped mesoporous carbon spheres (NMCSs) supporting anatase TiO 2 ( NMCSs – TiO 2) were prepared by a simple two-step solvothermal approach. The characterizations for the physicochemical properties of prepared samples under different solvothermal temperatures were carried out by X-ray diffraction (XRD) analyses, scanning electron microscopy (SEM), transmission electron microscopy (TEM), N 2 adsorption–desorption (Brunauer–Emmett–Teller (BET) measurements), Fourier transform infrared (FT-IR) spectroscopy, Raman scattering and UV-Vis diffuse reflectance spectra, were combined in order to determine the crystal phase and grain size, shape, degree of mesoporous carbon incorporation, and nature of the resultant oxycarbide chemical bonding on the surface and in the bulk. The high relative photocatalytic activity of NMCSs – TiO 2 nanoparticle was evaluated through a study of the decomposition of phenol under visible-light excitation.
