| 摘 要： | 采用复合模板表面活性剂辅助水热法一步合成了WO3/ZrO2多级孔固体酸催化剂,并应用X射线衍射、低温N2吸附-脱附、拉曼光谱及NH3程序升温脱附对催化剂进行了表征.结果表明,WO3的引入使得WO3/ZrO2催化剂的比表面积增大,表面的酸中心明显增加.在乙酸和正丁醇的酯化反应中,WO3/ZrO2多级孔固体酸催化剂表现出较...

| Abstract: | 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,N2 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 por... |
