Summary: This study evaluates the removal of three emerging pollutants, triclosan, 2,6-dichlorophenol, and bisphenol A, from water using Fenton-like and photo-Fenton-like reactions. The catalysts used were montmorillonite (Mt) and aluminum interlayered pillared clays (Al-PILC). The results showed that almost 100% of triclosan and 2,6-dichlorophenol can be removed using Al-PILC based catalysts.

Summary: By supporting NiFe2O4 onto montmorillonite, a highly active and reusable catalyst for methyl violet oxidation was obtained. Through XRD, TEM, XPS, and VSM analyses, it was found that the concentration of precursor played a crucial role in determining the specific surface area, NiFe2O4 particle size, and magnetism. The study also revealed that adsorption had an impact on both the enhancement of catalytic activity and the stability of the catalysts.

Summary: This review discusses the application of various materials as catalyst supports, including activated carbon, biochar, and fibers. It introduces the advantages and optimum conditions of different catalysts. Alginate-based catalysts are easy to prepare and exhibit high degradation efficiency. Zeolite-based catalysts are structurally stable and perform well in successive cycles. Fiber-based supports have both catalytic and cathodic functions due to their flexibility and conductivity. Graphene and carbon nanotubes have highly stable and conductive properties, promoting electron transfer.

Summary: The hematin-catalysed decolourization of alizarin red S solutions was studied in this research to understand the competition between peroxidatic and pseudo-catalatic routes. Absorbance and dissolved oxygen were measured over time, with hematin either in solution or immobilized onto chitosan. The experimental data were properly reproduced by the modelled dye concentration profiles, and the optimized rate constants showed that immobilization reduced hematin activity, emphasized dye inhibition, and promoted the pseudo-catalatic pathway. The findings were supported by the changes in oxygen evolution rates with H2O2 and dye concentrations, and the UV-visible stack spectra allowed the proposal of degradation products.

Summary: The adsorption and photo-Fenton degradation of tetracycline over Fe-saturated nanoporous montmorillonite were analyzed. The modified montmorillonite showed improved adsorption and photocatalytic degradation properties for tetracycline, and the high concentration of OH radicals in the porous structure facilitated tetracycline degradation. Additionally, the desorbed tetracycline from the modified montmorillonite exhibited weaker antimicrobial activity, making it a suitable substance for separating tetracycline from the environment.

Summary: Acetamiprid, a recalcitrant pollutant in wastewater treatment plant effluents, poses a potential threat to human health, aquatic life, soil microorganisms, and beneficial insects. In this study, α-Fe2O3-pillared bentonite (FPB) was synthesized and used in the photo-Fenton process, with the assistance of L-cysteine (L-cys) present in natural aquatic environments, for the degradation of acetamiprid. The degradation rate constant (k) of acetamiprid by FPB/L-cys in the photo-Fenton process was significantly higher than that in the Fenton process of FPB/L-cys without light and the photo-Fenton process of FPB without L-cys. The synergistic effect of L-cys and visible light was found to accelerate the cycle of Fe(III) to Fe(II) in FPB/L-cys, enhancing the visible light response of FPB and promoting interfacial and photo-generated electron transfer for acetamiprid degradation.

Summary: The study developed a H2O2-free photo-Fenton process using BiVO4 as a semiconductor and Fe3+ as an additive to effectively degrade antibiotics. Comparisons between H2O2-free photo-Fenton and photocatalytic reactions showed the former had higher degradation rates under optimized conditions. The study deepened the understanding of mechanism and kinetics between photo-Fenton and photocatalytic reactions on the same catalyst, and highlighted the potential of H2O2-free photo-Fenton reactions on other semiconductors in treating wastewater with various antibiotics.

Summary: This study investigates the dry reforming of methane (DRM) through experimental and computational methods. The catalyst used, NiOx/ZeoA, was synthesized by functionalizing nickel salt with oxalate ligand to ensure highly downsized Ni nanoparticles interaction with zeolite A support (ZeoA). The presence of in situ sodium atoms increases the catalyst basicity, facilitating CO2 activation. The computational results show that isomorphic substitution of Al and Si atoms with Ni atoms narrows the bandgap and excites Ni's 3d electrons into the conduction band. The addition of Ni reduces the intensity of negative charges on O atoms. This catalyst demonstrates high CO2 and methane activation with stability and resistance to carbon deposition.
