Summary: Photocatalytic CO2 reduction into chemical fuels is a promising strategy for CO2 conversion and solar energy utilization, but conversion efficiency remains a challenge. In this study, Ag-ion-doped CuV2O6 nanowires with abundant oxygen vacancies were prepared and used as catalysts for CO2 photoreduction. The Ag-doped CuV2O6 nanowires exhibited enhanced visible-light absorption ability, abundant oxygen vacancies, and high separation/transfer efficiency of electron-hole pairs, resulting in excellent photocatalytic performance for CO2 reduction. The optimized Ag-doped CuV2O6 nanowires showed a significantly enhanced CO evolution rate under visible-light irradiation compared to pure CuV2O6 nanowires. This work provides a valid strategy for improving visible-light photocatalytic CO2 reduction using CuV2O6 nanowires.

Summary: In this study, boron-containing MgO by-products obtained from lithium extraction in Qarhan Salt Lake, China, were used as substitutes for dead-burned MgO to prepare magnesium phosphate potassium cement (MKPC) as a rapid repair material. The effects of different MgO sources, molar ratio of MgO to KH2PO4, and curing age on the setting time and mechanical properties of MKPC were investigated. The results showed that the by-product MgO prolonged the setting time of MKPC, but with increasing age, the mechanical properties of MKPC prepared by by-product MgO were excellent. The study also characterized the phase and microstructure evolution of MKPC prepared with different MgO contents.

Summary: La2S3/SN-biochar composites were prepared by modifying S,N-codoped biochar with La2S3, which significantly improved the adsorption and photocatalytic activities for tetracycline hydrochloride removal. The optimal 3c-La2S3/SN-biochar with a La content of 15.43 wt% and an N content of 0.49 wt% exhibited the highest TCH removal efficiency. However, long-term photo-corrosion led to decreased adsorption-photocatalytic efficiency and decreased adsorption capacity.

Summary: BiOCl0.5X0.5 (X = F, Br, and I) heterojunctions were prepared for the solar-light induced photodegradation of tetracycline hydrochloride (TCH). Among the samples, BiOCl0.5I0.5 exhibited the best photocatalytic activity. The Z-scheme junction between BiOCl and BiOI facilitated the efficient separation and migration of photo-generated charge carriers, and the narrow band-gap structure of BiOCl0.5I0.5 microspheres favored visible-light harvesting. The solar-light deactivation of BiOCl0.5I0.5 was attributed to the change in valence states induced by photo-corrosion.

Summary: Using various analysis techniques, the study investigates the degradation process of magnesium oxychloride cement (MOC) in outdoor dry-wet environments. As the number of dry-wet cycles increases, water molecules gradually penetrate the MOC samples, leading to the hydrolysis of P5 and hydration reactions of unreacted active MgO. This results in the appearance of cracks on the surface and warped deformations. The microstructure of the MOC samples changes from a gel state to a flake shape, with a loose structure. The compressive and flexural strength of the samples decrease significantly after multiple cycles.
