| مستخلص: | Aim: In the present work, the preparation and catalytic activity of spinel ferrite(MFe2O4; M = Fe, Mn, Co, Cu, Ni) nanoparticles to synthesize 5-hydroxymethylfurfural (HMF)have been discussed. Background: Ferrites possess unique physicochemical properties, including excellent magneticcharacteristics, high specific surface area, active surface sites, high chemical stability, tunableshape and size, and easy functionalization. These properties make them essential heterogeneouscatalysts in many organic reactions. Objective: This study aims to synthesize a series of transition metal ferrite nanoparticles and usethem in the dehydration of carbohydrates for 5-hydroxymethylfurfural (HMF) synthesis. Method: The ferrite nanoparticles were prepared via the co-precipitation method, and PXRDconfirmed their phase stability. The surface area and the crystallite size of the nanoparticles werecalculated using BET and PXRD, respectively. Result: The easily prepared heterogeneous nanocatalyst showed a significant catalytic performance,and among all spinel ferrites, CuFe2O4 revealed maximum catalytic ability. Conclusion: Being a heterogeneous catalyst and magnetic in nature, ferrite nanoparticles wereeasily recovered by using an external magnet and reused up to several runs without substantialloss in catalytic activity. HMF was synthesized from fructose in a good yield of 71%. |
