This study explores the potential of LDH flakes decorated with metallic oxide nanoparticles to function as both anti-corrosion barriers against chloride anions and heterogeneous photocatalysts for tetracycline degradation under visible light. The process involves modifying primarily MgO-based inorganic porous film by growing a MgFe film, followed individual dual incorporation SnO2 WO3 nanoparticles. these into matrix leads synergistic interactions, effectively sealing pre-existing defects within facilitating in-situ formation catalytic sites through oxidation induction surface oxygen vacancy defects, which synergistically contribute enhancement electrochemical photocatalytic activities. enhanced stability is reflected in significant reduction corrosion current density 4 orders magnitude compared unmodified film. Additionally, demonstrates sustained functionality, achieving (95.5 %) two hours. presents novel approach, highlighting effectiveness LDHs metal oxides an anti-corrosive agent photocatalyst, promising implications environmental remediation wastewater purification.

Published: Dec. 28, 2024

Abstract MXene-based (nano)materials have recently emerged as promising solutions for antibiotic photodegradation from aquatic environments, yet they are limited by scalability, stability, and selectivity challenges in practical settings. We formulated Fe 2 O 3 -SiO /MXene ternary nano-photocomposites via coupled wet impregnation sonochemistry approach optimised tetracycline (TC) removal (the second most used worldwide) water using response surface methodology-central composite design (RSM-CCD). The photocatalysts containing various loading of /SiO (5–45 wt%) on the MXene with a range calcination temperatures (300–600 °C) RSM optimisation were synthesised, characterised regarding crystallinity properties, morphology, binding energy, light absorption capability, analysed TC degradation efficiency. 25FeS/MX-450 among all samples demonstrated superior efficiency photocatalytic (98%) under conditions (TC degradation: 39.75 mg/L, time: 68.28 min, pH: 5.57, catalyst dosage: 0.75 g/L). developed area, reduced band gap due to FeS nanoparticles incorporation improved within visible spectrum, played crucial role heterostructure matrix, enhancing photogenerated carriers’ separation transportation capabilities. photoreduction mechanism involved electron transfer MXene, engaging produce •O −, attributed high mobility MXene. Our findings such materials can underscore considerable potential nanomaterials pharmaceutical waterways.
