Catalytic exercise of C60 fullerene nanowhisker–zeolitic imidazolate framework-67 composite for discount of 4-nitrophenol: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0


Summary

The liquid–liquid interfacial precipitation technique was used to arrange C60 fullerene nanowhisker (FNW)–zeolitic imidazolate framework-67 (ZIF-67) composite from a ZIF-67 resolution, C60-saturated toluene, and isopropyl alcohol. X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM) have been used to characterize the synthesized C60 FNW-ZIF-67 composite. Its catalytic exercise for the discount of 4-nitrophenol was confirmed by UV–seen (UV-vis) spectroscopy. C60 FNW–ZIF-67 as a catalyst displayed a discount of 4-nitrophenol (4-NP) to 4-aminophenol (4-AP) for 20 min with a charge fixed of 1.379 × 10−1 min−1 (at 25 °C), 5.761 × 10−2 min−1 (at 15 °C), and three.113 × 10−2 min−1 (at 5 °C), respectively. A kinetics examine indicated that the hybrid nanocomposite catalyzed the discount of 4-nitrophenol in response to a pseudo-first-order response charge equation. The thermodynamic parameters of activation, particularly, the enthalpy of activation (ΔH) of 48.966 kJ mol−1, the entropy of activation (ΔS) of −97.479 J mol−1 Ok−1, and the activation power (ΔEa) of 51.167 kJ mol−1, have been obtained utilizing the Eyring and Arrhenius equations.
