Summary: A new passivation method using H2O2-TiO2 interlayer enables effective interfacial bridging between TiO2 and perovskite in C-PSCs, leading to improved photovoltaic performance. By varying the spin coating speed, a suitable TiO2/HT-3000 ETL matrix with low oxygen vacancy and high-quality perovskite film growth was obtained. The TiO2/HT-3000 ETL-based C-PSCs achieved a PCE of 16.23% and showed enhanced long-term stability without encapsulation.

Summary: The photocatalytic decomposition of methylisothiazolinone (MIT) in water was achieved using TiO2 and TiO2/persulfate systems under simulated solar irradiation. The synthesized TiO2 catalysts were characterized by XRD, SEM, and N2 adsorption-desorption isotherms. The photocatalytic activity of the catalysts for MIT degradation was found to depend on the water provision method and calcination temperature. Addition of persulfate enhanced the MIT degradation rate due to a synergistic effect between the titania catalysts and PS activation. The complete mineralization and non-toxicity of the water solution after photocatalytic treatment were confirmed by TOC and toxicity measurements.

Summary: Given the ease of synthesis and polarization of bromine compared to homomorphic fluorine and chlorine, it is surprising that high-performance brominated small molecule acceptors are rare. This may be due to undesirable film morphologies caused by steric hindrance and excessive crystallinity. To overcome this, three acceptors were constructed with stepwise bromination on central units to enhance intermolecular packing, crystallinity, and dielectric constant without damaging favorable intermolecular packing through end groups. As a result, PM6:CH22-based binary organic solar cells achieved the highest efficiency of 19.06% for brominated acceptors, and a record-breaking efficiency of 15.70% when the active layers were further thickened to around 500 nm. By exhibiting such a rare high-performance brominated acceptor, this work highlights the potential for achieving record-breaking organic solar cells through delicate bromination.

Summary: This study systematically investigated the activation performance of coke powder (CP) towards persulfate (PS) and discussed its mechanism for organic pollutant degradation. The results show that CP has highly disordered amorphous structures with abundant oxygenated functional groups (OFGs) and persistent free radicals (PRFs), which contribute to the excellent activity of CP for PS activation. The study also reveals that superoxide anion radical (O-2•) is responsible for the degradation of organic pollutants in the CP/PS system, and its generation is independent of dissolved oxygen. These findings provide important insights for the development of remediation materials using by-products of the coking process for wastewater treatment.

Summary: Photocatalytic production of H2O2 is a potential green route to a greener future. However, the productivity is limited by rapid electron-hole separation and low oxygen reduction activity. In this study, a series of carbon nitrides with covalently bonded dual-functional ligands were designed to enhance H2O2 production and stability. The best-performing carbon nitride showed a high production rate and excellent stability. Mechanistic studies revealed that H2O2 was produced through a 2e(-) oxygen reduction reaction route. The excellent photocatalytic performance was attributed to the dual-functional ligand.

Summary: Three random double-cable conjugated polymers were designed with enhanced acceptor contents to achieve high-performance single-component organic solar cells (SCOSCs) by tailoring the nanophase separation of electron-donating and electron-accepting segments. The aggregation degree and charge-transporting pathways were influenced by the acceptor contents, and an optimal nanophase separation resulted in a high efficiency of 9.4% in SCOSCs. Random double-cable conjugated polymers serve as an excellent model for studying the impact of aggregation/crystallinity on high-performance SCOSCs.

Summary: The rapid fabrication of high-performance composite membranes based on CMPs using simple and low-cost methods is challenging. In this study, three CMPs-based composite membranes were rapidly fabricated with adjustable size using unidirectional diffusion synthesis. The microstructural design enhanced the rejection rates of the membranes and they showed strong hydrolytic resistance, thermal stability, and acid-base resistance. Electrostatic adsorption and the adjustable microstructures significantly varied the repellence of the membranes to different charged molecules.

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.
