“…The loading of WO 3 onto TiO 2 enhanced the visible light absorption and accelerated the degradation rate of diethyl phthalate under UV or blue light irradiation. Ma et al 50 deposited CeO 2 onto TiO 2 nanorod electrodes by liquid DBD plasma, using CeO 2 powder as precursor. They found that the formation of oxygen vacancies in CeO 2 /TiO 2 heterojunctions could enhance the ratio of Ce 3+ /Ce 4+ , improving the photoelectrochemical performance.…”

“…It enables reactions to be easily carried out under mild conditions without the addition of chemicals, thereby offering the advantages of low energy consumption and low environmental impact [ 29 ]. Many studies have reported that TiO 2 -based composite photocatalysts modified by DBD can exhibit excellent surface properties and enhanced absorption of visible and infrared light [ 30 , 31 , 32 ]. Further, the reaction preparation process can be significantly simplified and the catalyst can be quickly prepared.…”

A novel photocatalytic functional coating was prepared with g-C3N4/TiO2 composites as the photocatalytic active component modified by dielectric barrier discharge (DBD), and it showed an efficient catalytic performance under solar light irradiation. The degradation of xylene released from fluorocarbon coating solvents by the g-C3N4/TiO2 composite coatings was investigated under simulated solar irradiation. The degradation efficiency of the coating mixed with DBD-modified 10%-g-C3N4/TiO2 showed a stable, long-lasting, and significantly higher activity compared to the coatings mixed with the unmodified catalyst. Ninety-eight percent of the xylene released from fluorocarbon coating solvents was successfully removed under solar light irradiation in 2 h. The properties of the catalyst samples before and after modification were evaluated using scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), ultraviolet–visible (UV–vis) spectroscopy, X-ray photoelectron spectroscopy (XPS), and other characterization techniques. The results suggested that DBD-modified g-C3N4/TiO2 showed an improved capture ability and utilization efficiency of solar light with reduced band gap and lower complexation rate of electron–hole pairs. The prepared photocatalytic coating offers an environmentally friendly approach to purify the volatile organic compounds (VOCs) released from solvent-based coatings.
