Summary: This article summarizes the application of metal-free graphitic carbon nitride (g-C3N4) based direct and indirect Z-scheme photocatalysts in solar-driven advanced oxidation processes (AOPs) for the removal of organic pollutants from water. The classification of AOPs, definition and validation of Z-schemes are discussed, followed by an examination of the engineering strategies for CN-based direct Z-scheme structure and the design of indirect CN-based Z-scheme systems using different charge mediators. The relationship between Z-scheme structure and activity is studied to gain insights into improving the catalytic performance of CN-based Z-schemes in AOPs.

Summary: A Bi2WO6/NH2-UiO-66 nanocomposite with enhanced photocatalytic performance for ciprofloxacin degradation under solar light irradiation was developed by integrating NH2-UiO-66 with Bi2WO6 micro/nanoflowers. The Z-scheme heterojunction formed between NH2-UiO-66 and Bi2WO6 micro/nanoflowers showed effective photo-induced electron-hole pair separation and charge transfer kinetics, leading to significant degradation of ciprofloxacin. The photocatalytic mechanism involves the generation of h(+) and O-2(-) radicals as major reactive species in the composite.

Summary: This study focuses on the recovery of sinapic acid using liquid-liquid extraction assisted by a hollow fiber membrane contactor from an aqueous feed obtained through the hydrolysis of mustard bran. The screening of solvents of different chemical nature showed that all tested solvents had an extraction efficiency of more than 80% for pH < 5. Four solvents were selected for use in the hollow fiber membrane contactor, and the volatile solvents showed higher mass transfer coefficients compared to non-volatile solvents. The extraction efficiency was intensified by increasing the initial concentration of sinapic acid and the feed-to-solvent ratio. CPME was found to have optimal recovery efficiency at a phase ratio of 8:1, yielding 0.9 g of sinapic acid per liter of CPME used.

Summary: In this study, a nanofibrous layered structure of Ff-Ti3C2Tx-Co3O4 was prepared by self-assembling nanofibrous Co3O4 with lamellar fluorine-free MXene (Ff-Ti3C2Tx). The Ff-Ti3C2Tx-Co3O4 exhibited excellent catalytic activity for degradation, resistant to ionic interference, and maintained high removal efficiency of sulfamethoxazole (SMX) in municipal wastewater. The rapid SMX degradation involved fast electron transfer in redox cycles with PMS and the generation of 1O2 via PMS ->center dot O2 -> 1O2. This work provides new insights into antibiotic degradation mechanisms and electron transfer based on PMS activation.

Summary: In this study, sludge-derived biochar (SBC) was functionalized with various iron salts to enhance its adsorption ability for sulfamethoxazole (SMX) and magnetic collection performance. Ball milling was further employed to treat the optimal iron salt functionalized SBC (MSBC), resulting in ball milled SBC (BMSBC) with improved adsorption performance for SMX. The dominant driving mechanism for SMX adsorption onto BMSBC was confirmed to be multiple physicochemical forces, including 7C-7C conjugation, pore filling, H-bonding, Fe-O complexation, and electrostatic interactions. BMSBC exhibited favorable adsorption ability for SMX in actual waters and could be easily collected within 1 min due to its magnetic sensitivity.
