Summary: A high-performance adsorbent for phosphate removal, La-FACC, was developed by impregnating lanthanum on a composite material. The adsorption kinetics were well fit by the intra-particle diffusion model and pseudo second-order kinetic model, indicating chemisorption as the main mechanism. The Langmuir isotherm described the adsorption behavior well, showing high capacity and selectivity for phosphate removal under a wide pH range and high ion strength.

Summary: This study investigated the early water stability of Magnesium Potassium Phosphate Cement (MKPC) blended with Calcium Aluminate Cement (CAC) and Wollastonite (WS). The presence of CAC extended the setting time of MKPC macroscopically due to the stimulating effect of the admixture on the composite retarder. The synergistic effect between CAC and WS enhanced the early water stability and compressive strength of MKPC under water curing. Microscopically, CAC participated in the reaction of the MKPC system, producing crystalline and amorphous products, while WS inhibited crack development and strengthened the brittle matrix.

Summary: The study demonstrates that chemically- and thermally-modified lignite with Ca2+ and Mg2+ cations provides a positively charged surface, improving aqueous phosphate uptake. The presence of mineral phases promotes more efficient phosphate uptake by CTL compared to raw or thermally treated lignite. Phosphorous uptake by CTL occurs through stoichiometric precipitation of various calcium and magnesium phosphates, offering high uptake capacities.

Summary: Rational design of graphitic carbon nitride (g-C3N4) engineered hematite (Fe2O3)/reduced graphene oxide (rGO) photocatalysts has been successfully employed for visible-light-driven photo-Fenton-like degradation of sulfamethoxazole (SMX). The optimal photocatalyst showed exceptional performance due to the successful integration of g-C3N4/Fe2O3/rGO, enabling efficient separation and migration of photoinduced charge carriers (e/h+). The study also optimized the photochemical decomposition efficiency by analyzing important reaction parameters such as catalyst loading, H2O2 dosage, pH, and temperature, and proposed a possible mechanism for SMX degradation based on the generation of reactive species and degradation intermediates.

Summary: In this study, the concentration and position of sulfur vacancies in ultrathin ZnIn2S4 nanosheets were successfully controlled to optimize the photo-driven lignin model reforming process, leading to excellent selectivity for hydrogen and chemical monomers. The proton migration pathway was modulated through sulfur vacancy engineering, achieving high concentrations of sulfur vacancies in the bulk and on the surface of ZnIn2S4. This provides new mechanistic insights into biomass photoreforming and elucidates the structure/chemistry-catalysis correlation of ZnIn2S4 photocatalysts, which are crucial for photocatalyst design and solar fuel production.

Summary: This study comprehensively analyzed the molecular transformation behavior of dissolved organic matters (DOM) during peroxymonosulfate (PMS) activation by biochar for organic degradation. Different types of reactions were observed, including oxidative decarbonization, dehydrogenation, dehydration, deheteroatomisation, hydration, and N/S oxidation reactions. Certain compounds present in DOM showed moderate or strong inhibition effects on contaminant degradation. This information can be used to regulate ROS composition and DOM conversion process in PMS systems and minimize the interference of DOM conversion intermediates on PMS activation and degradation of target pollutants.

Summary: A series of macroporous carbon nitride-supported single-atom transition metal catalysts have been developed for solar light-driven photocatalytic gaseous NH3 splitting. The optimized Ni-MCN catalyst shows a high H-2 production rate due to the presence of Ni-N-4 sites, which improve the optical properties, accelerate charge carrier separation/transfer, and boost NH3 splitting kinetics. These findings provide valuable guidelines for the rational design of single-atom catalysts for energy- and cost-effective photocatalytic NH3 splitting.

Summary: The relationship between the single-atom structure and catalytic activity in Fenton-like catalysis was investigated. Different molecular structures and a light-dependent mechanism were discovered. The Co-N1+3 configuration favored the formation and had higher catalytic activity, while the Co-N2+2 configuration had inferior catalytic activity and negative effects on the adjacent Co-N1+3 site. Additionally, a 100% nonradical reaction pathway that could be photo-switched to a nonradical/radical process by visible light was revealed. This work enriches the fundamentals of single-atom catalysis and provides new insights into the atomic metal structure, reaction pathways and mechanisms, and structure-activity relationships in organic degradation.
