Special Issue Information

Dear Colleagues,

Nanomaterials generally exhibit excellent performance. To avoid agglomeration of the nanoparticles, improve the performance and decrease the cost, a nanocomposite was suggested for replacing nanoparticles. As a consequence, various supports including metal oxides, carbon, clay minerals, etc., have been explored. Additionally, the role of additives is taken into consideration. The interaction between support or additive and the active composite determines the performance, including catalytic activity, adsorption performance, and so on.

The present Special Issue of “Nanocomposites for Catalysis and Environmental Protection” focuses on the research or application of nanocomposites in improving catalytic activity and favoring environmental protection. Environmental catalysis and energy conversion are very important in coping with the changing global climate and protecting the environment. A catalyst plays a key role in affecting the process of catalytic conversion. Furthermore, nanocomposites also play a crucial role in adsorption, enrichment and environmental detection. We cordially invite authors to contribute original research articles and review articles covering the current progress on nanocomposites for catalysis and environmental protection.

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. Full article
