Summary: This research presents an innovatively designed mechanism to activate the passivation layer on the surface of Fe-0 and construct an in-situ Z-scheme heterojunction for high-efficiency environmental remediation. By facile synthesis of a recyclable Fe0@black-TiO2 Z-scheme heterojunction, both the aggregation and passivation of Fe-0 and the low visible-light absorption of TiO2 were improved simultaneously. The results showed that the degradation efficiency of tetracycline (TC) with Fe0@black-TiO2 was significantly higher than that of pristine Fe-0 and black-TiO2, which can be attributed to the strong reduction ability of highly dispersed Fe-0 and the in-situ constructed Z-scheme heterojunction.

Summary: Biological invasions, especially by Spartina alterniflora, are significantly impacting the structure and functions of coastal ecosystems in China. Urgent efforts to control the spread of this invasive species are hindered by the lack of time-series data. By using satellite images, this study successfully generated annual maps of Spartina saltmarshes from 1985 to 2020, revealing a continuous expansion of Spartina along the coast. The invasion history and frequency of changes were found to be influenced by latitude, with low latitudes experiencing longer and more frequent invasions. Human interventions have contributed to the decline in certain areas, but natural spread remains the primary driver of its extensive invasion.

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.
