摘要：

Microwave-assisted hydrothermal synthesis of SnxSTA material was prepared with different treatment times (1 and 2 h), and efficient conversion of fructose to produce 5-hydroxymethylfurfural (HMF) was obtained. The synthesized catalysts were studied by N-2 sorption, X-ray powder diffraction, FT-IR, FE-SEM, pyridine-FTIR, TGA-DTA, and temperature-programmed desorption of ammonia (TPD-NH3). Microwave-assisted hydrothermal-synthesized SnxSTA-MW-2 exhibited excellent catalytic fructose dehydration with 98% of HMF yield at 120 degrees C for 2 h. The surface acidity was found to be crucial for optimum catalytic activity.
