Abstract
AbstractA series of Al2O3‐TiO2‐W materials with variation in W composition was prepared using an innocuous and easy sol‐gel method, under both acid and basic pH conditions. The morphology and composition of W in the materials were studied by Scanning Electron Microscopy (SEM) and Energy Dispersive X‐ray spectroscopy (EDS), respectively, Density of basic and acid sites by CO2 and NH3 temperature programmed desorption (TPD) technique, and physicochemical properties by N2 physisorption studies, X‐ray diffraction (XRD), and UV‐Vis spectroscopy. The catalytic properties of Al2O3‐TiO2‐W were examined for the conversion of glucose to produce 5‐hydroxymethylfurfural (5‐HMF) and the best yield of 5‐HMFobtained with the catalyst of 5 w% W load. This high yield level was achieved when the catalyst with 2.35 acid‐basic sites molar ratio was probed.
