摘要: Abstract The flexible topology, high surface area, porous structure, and unsaturated metal sites of metal-organic frameworks (MOFs) renders them promising candidates for the remediation organic pollutants. An environmentally benign, safe, energy-efficient synthesis process copper benzene dicarboxylic acid-based MOF (Cu-BDC) in choline chloride/urea deep eutectic solvent (DES), a green solvent, is described. present protocol Cu-BDC conserved 97% energy input as compared to traditional process. prepared was characterized following different spectrometric techniques such Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), BET scanning electron microscopy (SEM) X-ray powder diffraction (XRD) photoelectron spectroscopy (XPS) analysis. characterization good agreement with those reported MOF. subsequent heterogeneous Fenton-like catalytic application C.I. Acid orange 7 (AO-II) dye removal from water showed efficiency under mild reaction conditions. effect initial pH, catalyst loading, H2O2 concentration, temperature on performance investigated. best (99% degradation 74% COD removal) achieved 20 mL 30 mg/L AO-II concentration condition 5 mM H2O2, 0.05 g/L Cu-BDC, pH = 6.8, room temperature. Under optimum conditions, pseudo-first-order kinetics model well fitted experimental data. HRLC-MS performed identify products plausible pathway. exhibits recyclability without much loss its activity.
