摘要：

WO3/ZrO2 solid acid catalyst with hierarchically porous structure was prepared by the one-pot hydrothermal method involving templating from a composite surfactant. The catalyst samples were characterized by X-ray diffraction, N-2 adsorption-desorption, Raman spectroscopy and NH3 temperature-programmed desorption. The results indicated that WO3 doping significantly increased the BET surface area and provided more surface acid centers. The esterification of acetic acid and butanol showed that the hierarchically porous WO3/ZrO2 solid acid catalyst has excellent catalytic activity and reusability. The 20% WO3/ZrO2 sample calcined at 550 degrees C for 5 h has the highest catalytic activity.
