Molybdenum carbide anchored on glucose-derived carbon (β-Mo2C@C) as a bifunctional catalyst for conversion of fructose to 2, 5-diformylfuran. Issue 9 (15th March 2022) - Yang, Zhenzhen
Abstract : Molybdenum carbide anchored on glucose-derived carbon (β-Mo2 C@C) has been successfully synthesized and applied as a bifunctional catalyst for one-pot conversion of fructose to DFF. Abstract : Direct conversion of biomass-based fructose to 2, 5-diformylfuran (DFF) has attracted much attention in recent years. In this study, molybdenum carbide anchored on glucose-derived carbon (β-Mo2 C@C) was synthesized by a simple, green and economical method and was found to be highly active for production of DFF from 5-hydromethylfurfural (HMF) and fructose. DFF was obtained with high yields of 94.5% and 76.0% from aerobic oxidation of HMF and "one-pot" conversion of fructose under optimal reaction conditions, respectively. A probable mechanism involving Mo 6+ /Mo 2+ redox cycles was proposed for β-Mo2 C@C-catalyzed oxidation of HMF to DFF according to the experimental and characterization results. Furthermore, the β-Mo2 C@C catalyst can be reused without much loss of catalytic activity, suggesting that β-Mo2 C@C is highly stable.
