Summary: The synthesis of NT@CN core/shell structure S-scheme heterojunction photocatalyst was achieved by uniformly growing graphitic carbon nitride (g-C3N4) on the surface of nitrogen-doped rutile TiO2 (NT) nanorods. The as-synthesized heterojunction with 55 wt% g-C3N4 showed the highest CO2 photoreduction activity (33.35 μmol g(-1) for CO) without additional cocatalysts or external sacrificial agents, which was 7.1 times higher than that of bare NT nanorods. This improvement was attributed to the large surface area and impactful S-scheme heterostructure, enabling sufficient visible-light harvesting ability, segregation and transformation of charge pairs, and enhanced redox ability of carriers. Furthermore, the NT@CN photocatalyst displayed excellent reusability and stability. This work provides a new foundation for designing and preparing rutile TiO2-based S-scheme heterojunctions with enhanced CO2 reduction performance.

Summary: Combining the high surface area and CO2 adsorption capacity of metal-organic frameworks (MOFs) with efficient semiconductor photocatalysts is an effective approach for designing CO2 reduction photocatalysts. By controllably growing TiO2 nanoparticles on MIL-101(Cr) using a fluoride-assisted solvothermal method, MIL-101(Cr)@TiO2 core-shell photocatalysts are synthesized. The as-prepared MIL-101(Cr)@TiO2 nanocomposites, with their morphology, structure, surface area, and composition characterized, exhibit enhanced photocatalytic conversion of CO2 into CH4.

Summary: This study investigated the bioaccumulation capacity of Chlorella vulgaris and Spirulina platensis exposed to silver nanoparticles (AgNPs) and silver nitrate (AgNO3). The results showed that S. platensis could largely bioaccumulate silver nanoparticles while C. vulgaris greatly absorbed ionic silver (AgNO3). Both microalgae showed a concentration-dependent response to silver materials. AgNO3 had a significant impact on the average specific growth and yield of algal populations, and the content of pigments decreased in response to both forms of silver, with the highest severity observed for AgNO3.

Summary: This study assessed the contamination and health risks of heavy metals and organophosphorus pesticides in rice cultivation in Mazandaran province, Iran. Samples were collected from 17 locations in rice farms and analyzed for pesticide and heavy metal concentrations. The results showed varying levels of heavy metals in rice and soil samples at different farming stages. The risk assessment indicated no significant risk from consuming contaminated rice for adults and children, but potential non-carcinogenic risks were identified. Nickel posed the highest carcinogenic risks, and carcinogenic heavy metals were found in all stations. There were no significant ecological risks to the environment. Overall, while multiple cropping in rice farming has its benefits, the potential toxic effects of heavy metals and pesticides on consumers and the environment should not be ignored.
