The catalyst was easy to prepare and the synthesized catalyst was well characterized using different techniques such as FT-IR, P-XRD, EDAX, SEM, TEM and XPS analysis. The catalytic activity was evaluated for synthesis of a very important platform chemical 5-HMF from fructose to glucose using isopropanol as a solvent. The catalyst was found to be highly efficient giving 86% yield of 5-HMF from fructose and 45% yield from glucose with high selectively. The catalyst can be reused at least four times without depreciation in its catalytic activity. The catalytic method developed is efficient, green and economical.</p>
