Summary: Methanol steam reforming (MSR) is an efficient method for hydrogen production in fuel cell applications, and Pd-Zn catalysts are commonly used. To minimize Pd loading, PdZn nanoparticles (NPs) and Pd1/ZnO single-atom catalysts (SACs) were prepared through ball milling. The 2PdZn/Al2O3 NP catalyst exhibited excellent antioxidation ability and stability at 350 degrees C, with methanol conversion maintained at 99.5% and CO concentration below 0.71%. It showed promising potential for on-board hydrogen production for fuel cell vehicles.

Summary: A combination of powder metallurgy and mechanical alloying has been used to produce advanced Cu-based nanocomposites. Different material systems were synthesized using different ball milling times and reinforcements, and their properties were thoroughly analyzed. The results showed that increasing the milling time led to better dispersion and embedding of the reinforcements in the Cu matrix. The ball milling process also resulted in a reduction in particle size and an increase in hardness. However, the addition of reinforcements and longer milling times decreased the relative density of the samples.

Summary: This study utilized biochar as the substrate of the electrodes and employed a simple synthetic process (ball milling) to prepare the Fe3O4@biochar cathode enhanced electrochemistry-potassium per-sulfate system, achieving efficient removal of sulfadiazine. The results indicated that the catalytic performance of the cathodes was determined by the cracking temperature of biochar and the iron-to-carbon mass ratio. Additionally, ball milling increased the surface functional groups of biochar and facilitated the dispersion of Fe3O4 on biochar, leading to an increased number of active sites on the Fe3O4@biochar cathode surface. The coupled system of electrochemical-persulfate exhibited a removal rate of 95.3% for SDZ and 86.9% for TOC under specific conditions, and demonstrated excellent removal efficiency for sulfadiazine in actual water bodies.

Summary: A novel nanocomposite CeO2/Fe3O4/biochar (BC) was prepared by ball milling method and exhibited superior performance in tetracycline (TC) removal compared to other materials. The ball milling process not only reduced particle size and increased surface area for enhanced TC adsorption, but also increased the number of oxygen-containing functional groups to enhance TC degradation. The enhanced oxygen activation was attributed to the redox pairs of Ce4+/Ce3+ and Fe3+/Fe2+ and the presence of persistent free radicals (PFRs) in the nanocomposite.

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.
