Summary: Methanol oxidation shows potential for clean energy transition, especially in DMFCs. However, developing efficient and cost-effective catalysts for MOR remains challenging. We report the remarkable electrocatalytic activity and stability of Ni3Sn4 in acidic media, comparable to commercial Pt/C catalysts. Our catalyst design using Ni and Sn elements is 1800 times more cost-effective than Pt/C, as confirmed by DFT modeling. Additionally, the synthesized Ni3Sn4 electrocatalyst demonstrates excellent durability even after prolonged exposure to harsh acidic conditions.

Summary: In this study, Pt single atom supported on RuO2 exhibits highly active methanol oxidation compared to Pt single atom supported on carbon. The newly synthesized Pt-1/RuO2 catalyst shows significantly improved mass activity for methanol oxidation in alkaline media, surpassing most previously developed Pt-based catalysts. Additionally, Pt-1/RuO2 demonstrates high tolerance to CO poisoning and excellent catalytic stability, with the presence of unique Pt-O-3f-Ru-cus bonds contributing to lower energy barriers for the electrochemical dehydrogenation of methanol.

Summary: The study investigates the microstructural evolution of heterogeneous catalytic materials during the methanol electrooxidation reaction using a typical Au@Pd core-shell nanostructure. It reveals that an Au/Pd mixed bimetallic shell formed during the reaction reduces the binding strength of OH- and CO on the catalyst surface, leading to increased electrocatalytic activity. The exposed Au atoms in the shell region also produce large-scale reactive center dot OH radicals that facilitate the oxidative removal of adsorbed carbonaceous species from the adjacent Pd active sites.

Summary: A facile and green strategy is proposed for preparing porous carbons (Ma-NaCl-X) from ammonium lignosulfonate with the assistance of sodium chloride. The catalytic effect of molten NaCl significantly enhances the order and electrical conductivity of Ma-NaCl-900 prepared at 900 degrees C compared to Ma-NaCl-800. When carbonization temperature reaches 1000 degrees C, NaCl's catalysis and activation effects result in sharp increases in specific surface area, micropore volume, and sp2 carbon content of Ma-NaCl-1000. Furthermore, Ma-NaCl-1000 exhibits ultrahigh electrical conductivity and considerable surface area, enabling a symmetrical supercapacitor to deliver high energy density and retain impressive values at ultrahigh power density. Additionally, Ma-NaCl-700 with suitable heteroatom content shows a high specific capacitance and excellent rate capability in an aqueous symmetric supercapacitor.

Summary: This study investigated the use of boron-based materials on efficiency of environmentally friendly porous ceramics. A glaze formulation was created using high amounts of frit and low-temperature sintering. Boric acid and colemanite were added to the glaze, and different formulations were created by reducing the frit percentage. X-ray crystallography analysis revealed the crystal phase structures of glaze samples, while scanning electron microscopy was used to examine the surface properties of the samples. Differential thermal analysis and thermogravimetric analysis were performed to determine their thermal behavior. The results showed that boron derivatives act as a good flux agent without negatively affecting the surface and technical properties of the glaze.

Summary: In recent years, there has been growing momentum in the research on dye removal and hydrogen energy. However, the existing methods for dye removal, both biological and physical, are inadequate. Similarly, the efficiency of hydrogen production without a catalyst is very low. Therefore, it is crucial to obtain inexpensive catalysts for both purposes.

Summary: This study aimed to investigate the diffusion heat of dopant anions and cations in the natural apatite structure. The results showed that the diffusion of additive atoms increased between the two heat stages. It was also found that sintering at temperatures of 800-850°C for the first stage and 1080-1250°C for the second stage resulted in optimal diffusion and high relative density. When sintered in a gas atmosphere, the anions could resettle in the apatite structure, leading to a highly stabilized structure. Additionally, sintering under pressure instead of solid-state sintering increased particle-to-particle interaction and maintained higher relative density.

It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
