Summary: Graphene oxide (GO) is a promising material in photocatalysis, adsorption, and energy storage due to its high surface area and unique layered structure. Anthracite coal is an attractive precursor for GO because it provides high concentration of sp(2) carbon, resulting in high conductivity and absorbance in the visible region. GO-TiO2 nanocomposites were prepared to enhance photocatalytic activity by facilitating electron transmission from TiO2 to GO, and Ag nanoparticles were coated on TiO2 to further boost activity.

Summary: Cu-doped WO3 square nanoplates were synthesized via a one-step hydrothermal process and exhibited excellent photocatalytic performance for CO2 photoreduction, surpassing that of pure WO3. The enhanced performance can be attributed to the more negative conduction band position, decreased bandgap energy, improved visible-light absorption capability, and efficient charge carrier separation and transfer of Cu-doped WO3.

Summary: The study identifies the oxygen vacancy concentration as linearly correlated with solar fuel yield in the photocatalytic activity of atomically thin BiOCl nanosheets. The presence of a weak p-sigma bond in the Bi-C-O-Bi geometry is responsible for the improved CO yield and selectivity. This work sets the stage for further exploration in the design of atomically thin 2D vdW photocatalysts.

Summary: In this study, a supported amorphous catalyst NiMo/TiO2 was synthesized, which efficiently decomposes hydrous hydrazine to produce hydrogen with excellent catalytic properties. The strong synergistic interaction between the support TiO2 and NiMo nanoparticles, as well as the doping of Mo leading to changes in the surface structure of NiMo/TiO2, contributed to the easier cleavage of the N-H bond and desorption of reaction intermediates.

Summary: In this article, the effect of crosslinker content on the properties of silicone rubber was investigated by studying the free volume holes in the samples. It was found that increasing the crosslinker content reduced the size of free volume holes but did not affect the concentration of holes. Additionally, surface cracks were observed on samples with high crosslinking levels after corona treatment, leading to a decrease in water repellency.

Summary: A novel photocatalytic functional coating was developed by modifying g-C3N4/TiO2 composites with dielectric barrier discharge (DBD), which exhibited high catalytic performance under solar light. The degradation of xylene released from fluorocarbon coating solvents was studied using g-C3N4/TiO2 composite coatings under simulated solar irradiation. Coatings mixed with 10% DBD-modified g-C3N4/TiO2 showed stable, long-lasting, and significantly higher activity compared to those mixed with unmodified catalyst. 98% of xylene was successfully removed in 2 hours under solar light. SEM, TEM, FT-IR, UV-vis, XPS, and other techniques were used to evaluate the properties of the catalyst samples before and after modification, suggesting improved capture ability and utilization efficiency of solar light.

Summary: Cooking oil fume (COF) is associated with health risks, and this study investigated the particle number size distribution (PNSD) of COF and its spatial distribution and influencing factors. The PNSD was found to follow a lognormal distribution, with peak diameters decreasing as the distance from the source increased. The decrease in temperature from the pot to the indoor environment led to a reduction in surface partial pressure of COF particles and the condensation of semi-volatile organic carbons (SVOCs) on the COF surface. The amount of edible oil used in dishes was positively correlated with COF concentration. Techniques for cleaning small size particles and improving air ventilation should be considered.
