Summary: In this study, reduced graphene oxide (RGO) was prepared using a modified method, and an RGO/TiO2 nanotubes photoelectrode was developed. The photocatalytic activities of the RGO/TiO2 NTs were examined, showing that the structure of TiO2-NTs remained unchanged after RGO modification, with an increased thickness of the RGO/TiO2 NTs and lower impedance compared to TiO2 NT photoelectrode. Optimal preparation conditions for RGO/TiO2 NT photoelectrodes were determined through single factor and response surface methods.

Summary: A Cu2O/BaHPO4 photoanode with high activity was synthesized using a simple electrodeposition technique. The material was characterized by XRD and SEM-EDX, showing orthorhombic BaHPO4 and cubic Cu2O phases. DRS was used to evaluate the optical features and band gap energies. The electrocatalytic activity of the samples was evaluated using CCD-RSM, and the optimal conditions for Rhodamine B degradation were determined. The Cu2O/BaHPO4 photoanode exhibited a photo-electrocatalytic performance of about 98% in 5 minutes of reaction under visible irradiation, indicating excellent synergetic properties. The high cyclability of the photoanode was confirmed, making Cu2O/BaHPO4 a promising candidate for efficient degradation of organic pollutants.

Summary: In this study, an eggshell-loaded CoFe2O4 catalyst was synthesized using a convenient hydrothermal method. The surface morphology and elemental composition of the composites were investigated. The performance of the CoFe2O4/eggshell-activated peroxymonosulfate (PMS) system was evaluated using florfenicol (FF) as a model pollutant, and the effects of operating parameters and water matrices on FF removal efficiency were studied. The main radicals involved in FF degradation were identified, and a possible mechanism was proposed. It was confirmed that the toxicity of FF was reduced during degradation, and dehalogenation and defluorination reactions were effectively carried out. The prepared CoFe2O4 polyvinylidene fluoride (PVDF) membrane improved material stability and reduced metal precipitation.

Summary: Introducing defects into porous metal-organic frameworks is important for improving their adsorption performance. Quasi-MOFs, an underutilized variant of large-scale, fundamentally deficient MOFs, have been found to have substantial amounts of unsaturated metal sites to offset the drawbacks of MOFs. In this study, a quasi-MOF was produced using a water-stable MOF and demonstrated significantly improved phosphate adsorption capability due to the presence of defect sites.

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.
