The synthesis of high-performance catalysts for volatile organic compounds (VOCs) degradation under humid conditions is essential their practical industrial application. Herein, a codoping strategy was adopted to synthesize the N-Co3O4-C catalyst with N, C low-temperature ethyl acetate (EA) conditions. Results showed that exhibited great catalytic activity (T 90 = 177 °C) and water resistance (5.0 vol% H2O, T 178 EA degradation. Characterization results suggested C, N weakened Co-O bond strength, increased surface Co3+ Oads species, improved redox ability mobility lattice oxygen which boosted performance Meanwhile, N-doping-induced vacancies could interact vapor generate extra active enhanced resistance. Importantly, based on series characterization technologies, in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), theoretical calculations, synergistic effect systematically investigated elucidated. doping induced increase area weakening adsorption species activation dissociate oxidize EA, forming key intermediate, acid. gaseous form attacking breaking C-C acid accelerate deep oxidation, synergistically facilitated

Carbon Neutrality, Journal Year: 2024, Volume and Issue: 3(1)

Published: June 1, 2024

Abstract Environmental contamination by hexavalent chromium (Cr(VI)) and antibiotic drug residues pose significant challenges to public health ecosystems. This study investigates the application of CoTiO 3 /BiVO 4 @MIL-Fe(53) (CT/BV@Fe-MOF) for reduction Cr(VI) degradation tetracycline (TCL) under visible light. After grafting an iron-based metal–organic framework MIL-Fe(53) on a modified composite, photogenerated electrons could easily be transferred from BiVO /Fe-MOF species via interfacial charge transfer. UV–vis diffuse reflectance spectroscopy showed that carriers were formed in response light absorption. The effect different operating parameters, including catalyst load, pH, initial Cr(VI), TCL concentration, was systematically evaluated during photocatalytic process. CT/BV@Fe-MOF composite exhibited 98.7% efficiency (50 ppm) 97.5% towards (30 within 90 min, resulting greater than pristine , Fe-MOF materials. displayed excellent stability over six cycles, highlighting its potential practical applications. In addition, plausible pathway using LC-ESI/MS analysis, while TEST program utilized investigate toxicity products generated
