Summary: This study revealed a self-acclimation mechanism of pyrite in the oxidation process of sulfamethoxazole (SMX). The conversion of (OH)· to O1(2) was proven to be an important factor in the degradation of SMX. This mechanism overcomes the limitations of (OH)· and different oxidizing species have different degradation pathways and environmental toxicity.

Summary: This study demonstrates that digestive ripening of a physical mixture of different metal nanoparticles in the presence of a suitable ligand is a convenient method to obtain alloy nanoparticles. The choice of metal-ligand combination is crucial for efficient alloying, with the use of soft ligands for soft metals and hard ligands for hard metals resulting in better alloying. Intermediate character ligands work better for a physical mixture of hard-soft metals. These results could be extremely valuable and lead to new opportunities for creating interesting alloy/intermetallic systems.

Summary: Using a mixed solution of n-butanol and ethanol as a solvent, a sodalite nanocrystal aggregate was prepared through the solvothermal method. The effects of crystallization temperature, molar ratio Na/Al, crystallization time, and silane concentration on the morphology, crystallite size, degree of crystallization, and pore structure were investigated. The results showed that sodalite nanocrystals self-assembled to form a micropore-mesopore-macropore structure. Higher temperature and longer time favored the growth of sodalite nanocrystals, and a high Na/Al ratio was necessary for their formation. The appropriate silane concentration resulted in smaller crystal-sized sodalite nanocrystals, and removal of the silane agent produced a multistage porous structure with specific properties.

Summary: The synthesis of heteroatoms doped inorganic nanocrystal-carbon composites (INCCs) with homogeneous distribution of metal (alpha-Fe2O3) and non-metals (N, P, O) was achieved through a facile two-step route using hydrogel formed by treating hexachlorocyclotriphosphazene (HCCP) and 3, 4, 5-trihydroxy benzoic acid (Gallic acid). Four different samples (INCC-0.5%, INCC-1.0%, INCC-1.5%, and INCC-2.0%) were fabricated, showing uniform distribution of N, P, O, and alpha-Fe2O3 in the carbon architecture. INCC-1.5% exhibited superior catalytic performance in water oxidation catalysis (WOC), with higher methanol tolerance and stability compared to RuO2, attributed to the homogeneous distribution of alpha-Fe2O3 promoting initial O-2 adsorption and higher surface area with hierarchical pore size distribution facilitating ion transportation and mass-flux.

Summary: The usage of iron leads to the generation of hazardous scrap iron, but it can be used as an alternative source for fuel cell applications. Here, a single-crystalline nickel-based MOF (Ni-MOF) was synthesized as an electrocatalyst to produce hydrogen from scrap iron. The Ni-MOF/NF electrode shows improved performance due to the high catalytic activity of Ni-MOF and the organic ligands in the MOF structure. This Ni-MOF/NF electrode exhibits outstanding stability and is suitable for iron source-based fuel cell applications.

Summary: This study reports the design of a low-cost and scalable carbon-supported iron catalyst (K-Fe/NC) with tunable alcohol selectivity in Fischer-Tropsch synthesis. The catalyst exhibits a core-shell structure and facilitates the investigation of iron structural evolution. The dissociation and association of CO are thoroughly verified through theoretical calculations and experimental reactions. The synergistic effect between chi-Fe5C2/epsilon-Fe2C and Fe3O4 dual active sites is proposed as the mechanism for alcohol formation.

Summary: Greigite forms as an intermediate phase along the pyrite reaction pathway and may serve as a unique proxy for diagenetic and environmental conditions. Thermodynamic modeling reveals the optimal conditions for greigite formation in aqueous solutions, including anoxic and alkaline environments at or below 25 degrees C. Discrepancies between model and field observations suggest the importance of microenvironments in the formation and retention of greigite alongside pyrite.

Summary: In this study, a range of transition-metal-doped Cu-based single-atom alloys were investigated as catalysts for electrocatalytic nitrogen reduction reaction (e-NRR) using first-principles calculations. It was found that when the adsorption of N2 on the catalysts is strong enough, the inert N2 molecules can be effectively activated for the first hydrogenation step. Meanwhile, the last hydrogenation step is not affected by the scaling relationship and remains easy on all of the catalysts, which breaks the volcano-shaped relationship in e-NRR. Four promising catalysts with outstanding e-NRR activity and long-term stability were identified. This work provides a guideline for breaking the volcano-shaped relationship in e-NRR and designing highly efficient electrocatalysts.

Summary: This study designed two aluminum boron catalysts, R-AlB2 enriched with B-O rings and O-AlB2 enriched with B(OH)xO3-x oligomers, and found that R-AlB2 exhibited a higher selectivity of 30.2% in the high-temperature oxidative dehydrogenation of propane (ODHP), and remained stable for up to 200 hours. Multiple characterizations indicated that B-O rings were more advantageous for the production of propylene (C3=) via a dehydration pathway with lower energy barriers, while B(OH)xO3-x was primarily responsible for producing a small amount of C3=.

Summary: In this study, tunable arch-bridged reduced graphene oxide (rGO) nanofiltration membranes were developed through the application of voltage. These membranes demonstrated the ability to reject organic/anionic molecules under a finite voltage of 5 V. With assistance from the voltage, the positively-charged modified rGO membrane could universally reject both cationic and anionic dyes, even in harsh organic solvents. The efficient electrical modulation of these membranes was attributed to the synergetic effects of Donnan repulsion and size exclusion, making them promising for applications in industries such as pharmaceuticals.

Summary: In this study, we developed a surface-induced strategy to achieve excitation wavelength-dependent afterglow emission. The prepared PCz@DTT@paper system exhibited room-temperature phosphorescence afterglow with a lifetime of 1077.1 +/- 15 ms and a duration time of over 6 s. By adjusting the excitation wavelength, the afterglow emission could be switched on and off, showing remarkable excitation wavelength-dependent behavior. This work provides an effective strategy for constructing smart afterglow systems that can be fully utilized in various fields.

Summary: This study presents a new method of preparing lithium sulfide (Li2S) in air and at low temperatures, which shows enriched and surprising chemistry. The method utilizes a solid-state reaction between inexpensive and air-stable raw materials of lithium hydroxide (LiOH) and sulfur (S), resulting in Li2S as the major product. The success of this water-producing reaction in air is attributed to the stability of Li2S with oxygen at temperatures below 220 °C, the use of excess S to prevent water attack, and the expulsion of water by the carrier gas. Density functional theory computations explain the anti-hydrolysis of Li2S n and the decomposition of Li2S2O3 to recover Li2S. Furthermore, the homemade Li2S (h-Li2S) exhibits comparable performance to commercial Li2S (c-Li2S) as cathode materials for lithium-sulfur batteries (LSBs).

Summary: In this study, we report tunable arch-bridged reduced graphene oxide (rGO) nanofiltration membranes that can be modulated by applied voltage. The membranes exhibit complete rejection of organic/anionic molecules under a voltage of 5 V. By modifying the membrane with positive charges and applying voltage, the membranes show universal rejection of both cationic and anionic dyes, even in harsh organic solvents. The efficient electrical modulation is achieved through the synergistic effects of Donnan repulsion and size exclusion, enhanced by the electric field in arch-bridged rGO structures.
