In this paper, the WO3-embedded in mesoporous SiO2 framework (WO3@SiO2) was developed using facile modified sol-gel, and was further applied as the support of Pt/WO3@SiO2 catalysts during impregnation. The ring-opening of cyclic ether such as biomass-derived tetrahydrofurfuryl alc. (THFA), for selective synthesis of renewable 1, 5-pentanediol (1, 5-PeD), was efficiently accomplished over Pt/WO3@SiO2 catalysts. This special nanocomposite structure provided both abundant active sites and strong synergetic coupling, thus significantly boosting the catalytic performances. The effects of reaction parameters were also investigated on the catalytic performances, including W/Si molar ratio, reaction time, reaction temperature and reduction temperature The high THFA conversion of 82.9% and 1, 5-PeD selectivity of 72.9% were achieved under the optimized reaction conditions. The preliminary characterization results suggested that the Bronsted acid sites of HxWO3 species with proper acid amounts played an important role in controlling the selective ring-opening of THFA cyclic ether towards 1, 5-PeD.
