Description
Summary:ZnCr 2 O 4 nanoparticles with a high specific surface area have been fabricated using a hydrothermal synthetic process and were used as an effective catalyst to synthesize flavonoid derivatives. The textural and structural properties of the spinel were studied by X-ray diffraction (XRD), Field Emission scanning electron microscope (FE-SEM), nitrogen sorption techniques, and Fourier transform infrared spectroscopy (FT-IR). XRD confirmed the formation of cubic Zinc Chromite spinel with a small crystallite size of 5.04 nm. While Transmission Electron Microscopy (TEM) illustrated the particle size of ∼8, 10, and 16 nm. Textural analysis by N 2 sorption revealed a mesoporous system with a high specific surface of 215 m 2 /g for ZnCr 2 O 4 . Moreover, all desired flavonoids were obtained in high yields under solvent-free conditions with the aid of the ZnCr 2 O 4 catalyst. Structures of all flavonoid derivatives were confirmed by 1 H-NMR, 13 C-NMR, FT-IR, and their melting points.
