Summary: Advanced oxidation processes (AOPs) such as Fenton's reagent have drawbacks, but Electro-Fenton (EF) and heterogeneous Electro-Fenton (HEF) using mineral catalysts have gained attention. Mineral catalysts have advantages in efficiency, stability, affordability, and environmental friendliness, but challenges include agglomeration of nanoparticles and complex preparation techniques. The optimal pH range and dosage of catalysts and the performance of different catalysts are discussed. Further development is needed, considering the environmental impact. The article also emphasizes the need to achieve environmentally friendly and cost-effective results using real wastewaters on a pilot scale.

Summary: Mesoporous SBA-15 and x% WO3-SBA-15 catalysts were synthesized by a hydrothermal in-situ method and characterized using various analytical techniques. Among the catalysts, 5.5% WO3-SBA-15 exhibited the highest photocatalytic activity for the degradation of RhB, MB, and CV dyes under visible light irradiation. The trapping experiment confirmed that h(+) and O-2(center dot-) were the major species responsible for the photocatalytic degradation over 5.5% WO3-SBA-15 catalysts.

Summary: Waste cooking oil is an attractive feedstock for producing advanced biofuels due to its low cost and abundant availability. This study focused on the synthesis and analysis of mesoporous bimetallic catalysts for the catalytic deoxygenation of waste cooking oil. The results showed that the catalyst with 10% Ni-Fe/SBA-15 had the highest liquid yield but low selectivity towards the diesel fraction, while the catalyst with 5% Ni-Co/SBA-15 had the highest selectivity towards the diesel fraction.

Summary: Naproxen was impregnated into mesoporous SiO2 SBA-15 using the Supercritical Solution Impregnation (SSI) technique. The percentage of naproxen impregnated decreased with increasing CO2 density and with the addition of ethanol, ethyl acetate or menthol. The impregnated naproxen on SiO2 became amorphous and showed interaction with SiO2 support. Release tests showed a sustained release system with a slower rate compared to pure naproxen due to the interaction and diffusion of the drug.

Summary: Modulating the interaction between Mo nanoparticles and their support can finely tune the properties of the active site. In this study, molybdenum nitride catalysts supported on TiO2 and SBA-15 were prepared and characterized. The catalytic activity of Mo species was strongly influenced by the nature of the support, with SBA-15 being the most suitable for Mo dispersion. Mo species supported on a reducible oxide (TiO2) exhibited poor catalytic activity and quick deactivation in ammonia synthesis reaction due to charge transfer from the support. Differences in oxidation states, redox behaviors, and electronic properties were further studied.

Summary: Mesoporous silica (MPS) carriers have potential in increasing drug solubility and stabilizing amorphous drug delivery. A solvent-free method called milling-assisted loading (MAL) allows manipulation of the drug's physical state within the pores. This study investigated the effects of milling intensity and pore architecture on drug state and release. The results showed that decreasing milling intensity promoted nanocrystallization of the confined drug, and the chemical modification of the pore surface also enhanced nanocrystallization. The particle size of the composites had the greatest influence on the drug release profile.

Summary: This study investigates the use of chitosan hydrogel microspheres as a template for growing an extended network of MOF-type HKUST-1. Different drying methods (supercritical CO2, freeze-drying, and vacuum drying) were used to generate three-dimensional polysaccharide nanofibrils embedding MOF nanoclusters. The resulting HKUST-1@Chitosan beads exhibit uniform and stable loadings of HKUST-1 and were used for the adsorption of CO2, CH4, Xe, and Kr. The maximum adsorption capacity of CO2 was found to be 1.98 mmol center dot g(-1) at 298 K and 1 bar, which is significantly higher than those of most MOF-based composite materials. Based on Henry's constants, thus-prepared HKUST-1@CS beads also exhibit fair selectivity for CO2 over CH4 and Xe over Kr, making them promising candidates for capture and separation applications.

Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.
