Summary: The unintentional leakage of dyes into the aquatic environment has caused serious water contamination globally, risking the health of aquatic life and humans. Hence, there is a strong need for adaptable and effective measures to address this environmental challenge. In this study, a visible light-induced catalyst based on the Ce0.2Co0.8Fe2O4/g-C3N4 composite was synthesized using the hydrothermal technique. The catalyst's morphological, structural, and photoluminescence properties were characterized, and its photocatalytic proficiency was evaluated by degrading rhodamine B under visible light irradiation. The Ce0.2Co0.8Fe2O4/g-C3N4 composite demonstrated superior degradation potential compared to other catalysts, attributed to interfacial migration of photo-induced charge carriers. Additionally, the catalyst showed excellent stability in successive cycles, providing a low-cost approach for visible-light responsive catalysts in environmental remediation applications.

Summary: In this study, broad-spectral-responsive photocatalysts O-doped g-C3N4/Red P (OCN/RP) heterojunctions were prepared by mechanical grinding at room temperature, which showed enhanced photocatalytic activity against organic pollutant malachite green (MG). The enhanced activity is attributed to the effective charge separation at the interface between OCN and RP, and O-2(-) and OH• were identified as the main active substances in MG photo-degradation on OCN/RP. This experiment provides a general strategy for preparing non-metal photocatalysts with broad-spectral responsibility and improved catalytic activity.

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.
