Core-shell catalyst WO3@mSiO2-SO3H interfacial synergy catalyzed the preparation of furfural from xylose

A core-shell biacid catalyst WO 3 @mSiO 2 -SO 3 H was prepared. Through the core-shell structure, an interface with internal and external spatial relationship was formed, which was used to synergistic catalyze the preparation of furfural from xylose . And the conversion of xylose was as high as 98.7% and the furfural yield was 70.1% at 170°C for 4 h in water-toluene mixture (1:2 v/v%). The research provided a case for the preparation of furfural from xylose catalyzed by sulfonated core-shell catalyst and provided more application prospects for core-shell catalysts in biomass conversion .
