Summary: This study prepared CsBi2Ta5O16 as a photocatalyst for the first time and investigated its ability to convert CO2 and H2O into value-added products through photocatalysis. NiO-loaded CsBi2Ta5O16 composites showed efficient photocatalytic conversion of CO2 into CH4 and CO, and oxidation of H2O to O-2. The enhanced CO2 photocatalytic conversion was attributed to the adsorption and activation of CO2 on NiO. This work provides a design idea for a photocatalyst that enables the full reaction of CO2 with H2O.

Summary: This study investigated mono-haloacetic acids (mono-HAAs), a class of disinfection by-products commonly found in drinking water, due to their high toxicity. The toxic effects of mono-HAAs on human renal cells were explored, as well as the formation of mono-HAAs after chlorination and their relationship with water quality parameters. The study also tested the cytotoxicity of monochloroacetic acid (MCAA), monobromoacetic acid (MBAA), and monoiodoacetic acid (MIAA) on human embryonic kidney cells (HEK-293 T cells). The results showed that mono-HAAs formation was influenced by water quality parameters, and the cytotoxicity of mono-HAAs on HEK 293 T cells was possibly caused by the SN2 reaction of C-X bond with cellular molecules.

Summary: Oily wastewater discharge from industrial activities and oil spills has had a significant impact on human health and the global environment. Membrane separation is a promising solution for oily wastewater treatment, and this study successfully prepared a novel membrane by combining fibrous MXene nano-ribbons with mixed cellulose. The resulting MCE-MNRs membrane exhibited outstanding oil-water separation performance, with high water permeance and over 99% rejection rates for various oil-water mixtures. The membrane's excellent performance is attributed to the formation of a water layer during filtration, which allows water to pass through freely but blocks oil droplets.

Summary: Seeking earth-abundant and high-performance cocatalysts is crucial for efficient artificial photoreduction of CO2 to solar fuels. Six Ni species were evaluated as noble-metal-free cocatalysts for photocatalytic CO2 reduction. Results showed that NiS and Ni2P accelerated H2 evolution and decreased the selectivity for CO2 reduction, while Ni3C and Ni3N promoted CO2-to-CO conversion and inhibited proton reduction. The best-performing TiO2-Ni3N achieved a high CO production rate of 49.6 mu mol g(cat)(-1) h(-1) and a selectivity of 94.1% for CO2 reduction.

Summary: Solar-driven reduction of CO2 and H2O to methanol is improved by surface selenation strategy on metal cocatalysts. The formation of a stacked structure with a crystalline Rh core sandwiched between semiconductor substrate and amorphous selenated Rh (RhSe) shell is observed. The selenation of Rh shell reduces rate-limiting barriers for CH3OH production and inhibits side H2 evolution, leading to significantly enhanced photocatalytic activities and selectivities.
