SiO 2 and ZrO 2 supported W, Mo and Ga oxide catalysts were prepared by a sol-gel and wet-impregnation method. The 10 wt% WO 3 /SiO 2 (sol-gel) catalyst showed 61 ± 2% furfural yield from hemicellulose in a one-pot fashion for at least 8 cycles. Based on XRD, TPD and Hammett acidity characterization...

Description
Summary:SiO 2 and ZrO 2 supported W, Mo and Ga oxide catalysts were prepared by a sol-gel and wet-impregnation method. The 10 wt% WO 3 /SiO 2 (sol-gel) catalyst showed 61 ± 2% furfural yield from hemicellulose in a one-pot fashion for at least 8 cycles. Based on XRD, TPD and Hammett acidity characterizations, the catalyst structure-activity correlation was drawn. In a one-pot conversion of hemicellulose using acidic WO 3 /SiO 2 catalyst, 61% furfural yield was obtained for at least 8 cycles. The role of the metal and support on activity was elucidated.
