N-doped iron-based carbon is a promising catalyst to achieve peroxydisulfate (PDS) activation, but constructing efficient and stable catalysts with uniformly distributed firmly anchored nitrogen iron sources remains challenging. Herein, we developed magnetic porous (NMPC) through self-polymerization high-temperature pyrolysis of polydopamine Fe3+ coordination complexes explored it for PDS activation in antibiotic (tetracycline (TC) ciprofloxacin) degradation bactericidal detoxification. The NMPC/PDS system performed both radical nonradical catalytic pathways effective exhibiting 99.8% removal TC. Thanks the strong Fe3+, resulting NMPC could confine species N-carbonaceous matrices efficiently prevent severe leaching, demonstrating good recyclability. It maintain rate as high 92.4% after 5 cycles. After cycling, leaching only 0.026 mg/L, which much lower than WHO guideline value limits drinking water 0.3 mg/L. Moreover, exhibits excellent stability compatibility various conditions, including pH variations (3–9), coexisting substances, different sources. In addition, this an disinfection Escherichia coli Staphylococcus aureus, ratio more 99.9%. Toxic intermediate prediction cell toxicity experiments further prove that TC wastewater significantly reduced treatment system.

Ultrahigh‐Selectivity Photocatalytic Upgrading of Bio‐Aldehydes/Diols to Monoalcohols Via In Situ Circumventing Coupling Co‐Products Over Janus Single‐Atom Pd/TiO₂

Abstract Photocatalytic transfer hydrogenation of biomass‐derived aldehydes to alcohols often results in unwanted coupling co‐products. Herein, an ultraselective hydrogen system enabled by situ oxidative C─C bond cleavage over a Janus single‐atom palladium on titanium dioxide (0.5Pd/TiO 2 ) photocatalyst is presented. The TiO carrier promotes hydrogen‐donor activation, while Pd single atoms function as both electron and centers, enabling photocatalytic conversion bio‐based furfural furfuryl alcohol >99% yield using ethanol solvent/H‐donor at 25 °C. control/in experiments calculations reveal that 0.5Pd/TiO preferentially activates co‐formed by‐product undergo followed proton‐coupled transfer, exclusively producing alcohol. with good reusability applicable hydrogenative upgrading various aldehydes/diols into corresponding monoalcohols 81‒99% yields. This strategy offers new approach eliminate side reactions reductive unsaturated organics/biomass high selectivity.
