摘　　要：以钛酸丁酯和硝酸钾为主要原料,采用溶胶-凝胶法制备了K2Ti4O9晶须.利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)和比表面及孔径分布分析仪对试样进行了表征.结果表明,产物形貌为条带状,长径比大致为14∶1;所得K2Ti4O9晶须与氮气之间有弱的气-固相互作用,晶须之间交错堆积形成了介孔结构,比表面积为48.62m2·g-1.K2Ti4O9 whisker was prepared from tetrabutyl titanate and potassium nitrate by sol-gel method.The product was characterized by means of X-ray diffraction（XRD）,scanning electron microscope（SEM）and specific surface and pore size distribution analyzer.The results show that the product was banding,and the aspect ratio of the product was about 14：1.The K2Ti4O9 whisker had the weak gas-solid interaction with the nitrogen,and the staggered accumulation of the whiskers formed the mesoporous structure,and the specific surface area of the product reached 48.62m2·g-1.
