Summary: In this study, magnetic nanocomposite beads were prepared by incorporating magnetic Fe3O4 nanoparticles and natural iron ore (NIO) into sodium calcium alginate material, and were investigated as catalysts for the degradation of Nova-cron blue (NB) dye using Fenton and photo-Fenton processes. The as-prepared catalyst showed great photocatalytic behavior, and was successfully reused in six consecutive photo-Fenton tests. This catalyst has the advantages of low cost, environmental friendliness, non-toxicity, magnetic separability, and stability, making it a potential candidate for wastewater treatment applications.

Summary: This study investigated the elimination of methyl blue (MB) acidic dye from an aqueous solution using two types of modified montmorillonite. The adsorption efficiency of claytone and clay D2000 was 1.4 mg/g at pH 2 and 1.4 mg/g at pH 6, respectively. Pseudo-second-order was the best model to explain the adsorption process. The incorporation of MB/claytone and MB/clayD2000 into epoxy resin resulted in stylish colored epoxy nanocomposites with improved properties.

Summary: Fenton sludge was converted into magnetic sludge-based biochar (SMBC) which showed excellent catalytic efficiency in activating hydrogen peroxide for the oxidative removal of methylene blue. The crystal phase of Fe oxides in SMBC strongly influenced its catalytic activity, with the catalyst obtained at 800 degrees C for 1 h exhibiting the highest degradation efficiency. Free radical quenching experiments and electron paramagnetic resonance studies revealed the involvement of various radicals in the H2O2 system, and SMBC played a crucial role in generating .OH radicals. SMBC also showed good stability in non-aerated and aqueous conditions.

Summary: Passive daytime radiative cooling (PDRC) technology, while promising for global spacing cooling, faces limitations in practical application due to reduced cooling effectiveness caused by wear and dirt contamination. Researchers have developed a renewable armor structure using fluorinated hollow glass microspheres to enhance the anti-fouling and cooling properties of PDRC coatings. The coatings exhibit high solar reflectance and thermal emittance, leading to significant temperature reduction below ambient temperature.

Summary: Methane chemistry is a significant area of research in catalysis. Converting methane into value-added chemicals is desirable but challenging due to its high C-H bonding energy and lack of pi bonding or unpaired electrons. Photocatalytic partial oxidation of methane to liquid oxygenates is a promising technology for achieving high efficiency and selectivity under mild conditions. The choice and activation of oxidants are crucial for its performance.
