B-Modified Pd Cathodes for the Efficient Detoxification of Halogenated Antibiotics: Enhancing C–F Bond Breakage beyond Hydrodefluorination

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Halogenated antibiotics pose a great threat to aqueous environments because of their persistent biotoxicity from carbon–halogen bonds. Electrochemical reduction (ER) is an efficient technology for dehalogenation, but it still suffers limited efficiencies in breaking C–F Herein, we present strategy enhance cleavage and promote detoxification by loading benchmark palladium cathodes onto boron-doped carbon. This improves the florfenicol (FLO) degradation rate constant defluorination efficiency 1.24 1.05 times, respectively, various fluorinated compounds. The cathode with optimal B content shows superior mass activity FLO (1.11 mmol g–1 Pd min–1), which 5.9 times that commercial Pd/C among best-reported cathodes. Notably, exclusive formation direct product (i.e., FLO-F) on Pd/B–C implies higher intrinsic ability endowed doping. As revealed experiments theoretical calculations, boron modification enhances binding induces stronger strain effects electron density surface atoms, boosts H* generation reduces energy barrier cleavage. study provides effective design activation, may broadly benefit destruction organics are sluggish kinetics.

Abstract MoO 3 thin film was fabricated on an indium tin oxide substrate using the physical vapor deposition technique. X‐ray diffraction and scanning electron microscopy study to investigate surface morphology, grain size, structure, which are critical for absorbing solar spectra in water splitting hydrogen energy generation. Ultraviolet–visible spectroscopy used confirm absorption of percentage transmittance. Fourier‐transform infrared analysis provided functional groups present deposited film. The Tauc plot determine thin‐film band gap, allowed charge carrier transitions from conduction valence band. Electrochemical impedance investigations confirmed transfer processes counter electrode electrolyte interfaces. observed low curve indicated resistance efficient transfer. Linear sweep voltammetry measure photocurrent light emission when exposed spectra. film's rate 3731.74 mol g −1 h , STH% found be 0.345% at 0.8 V. These findings highlight promising potential as a material generation light.

The excessive use of pesticides has led to the harmful contamination water reservoirs. Visible-light-driven photocatalysis is one suitable methods for removal from water. Herein, development CBO (Co3O4-Bi2O3) as a heterogeneous catalyst visible light-assisted degradation Fipronil and Acetochlor reported. After synthesis via coprecipitation using cobalt (II) nitrate hexahydrate (Co(NO3)2·6H2O), bismuth (III) pentahydrate (Bi(NO3)3·5H2O) sodium hydroxide (NaOH) precursor materials, prepared was characterized advanced techniques including XRD, EDS, TEM, SEM, FTIR, surface area pore size analysis. Then, it employed photocatalyst under light irradiation. complete observed over 50 mL (100 mg/L) each pesticide separately within 120 min reaction. reaction kinetics investigated non-linear method analysis Solver add-in. exhibited 2.8-fold 2-fold catalytic performance in photodegradation selected than Co3O4 Bi2O3 did, respectively.

Abstract Till date it is a great challenge to synthesize CdS photocatalyst with high stability. In this study, stable was successfully synthesized by simple, cost‐effective hydrothermal route via cadmium acetate and thiourea as Cd S precursors, respectively. The effect of different processing times (8 h 24 h) molar ratios on the photocatalytic activity stability were mainly investigated. samples characterized in detail XRD, FT‐IR, XPS, UV‐vis DRS, Photolummiscence spectroscopy Surface photovoltage. as‐obtained nanostructures examined for methylene blue (MB) dye degradation under visible light irradiation (λ≥420 nm). After 70 min irradiation, nearly 82 % MB degraded nanostructures, display an improved apparent rate constant ( k ) 0.019 −1 . Additionally, sustained good photostability after five consecutive cycles. higher nanostructure attributed efficient separation photogenerated electron‐hole pairs stimulated its optimal ratio, temperature surface morphology. Our have potential contaminated waste‐water treatment.
