摘要: A series of supported B2O3/ZrO2–Al2O3 (BZA) catalysts with different loading B2O3 were prepared and characterized by XRD, FT-IR, XPS, NH3-TPD, N2 adsorption–desorption FT-IR (pyridine adsorption). These applied for direct conversion glucose to 5-hydroxymethylfurfural (HMF). An optimized HMF yield 41.2% at a 90.8% was obtained within 4 h 150 °C over (20 wt%)/ZrO2–Al2O3 (BZA-0.20). The best catalytic performance BZA-0.20 associated the highest amount total acid. simultaneously bearing Lewis acid Bronsted sites more efficient production from glucose.
