Size-Controlled C/N-Doped TiO2 Nanoparticles for Visible-Light-Driven Photocatalysis of Formaldehyde from Plywood

We reported a facile solvothermal approach to synthesize C/N-doped TiO2 (C/N-T) using a template-free method. The morphology and composition of the C/N-T were evaluated by transmission electron microscopy, X-ray diffraction, wavelength dispersive spectroscopy and X-ray photoelectron spectroscopy. The photodegradation of formaldehyde was studied in environmental chambers under specific conditions combined with UV-Vis determinations. The catalytic oxidations of C/N-T nanoparticles were characterized by degrading formaldehyde of plywood, which was induced via visible-light illumination. A maximum 95.7% of degradation efficiency within 55 min showed enhanced photocatalytic activity.
