纳米二氧化钛材料的制备与性能研究

Preparation and characterization of nano-titania

分别用溶胶-凝胶法与水热合成法制备了纳米二氧化钛.水热合成法与溶胶-凝胶法合成的纳米二氧化钛相比,比表面积很大,形貌比较规则;并且水热法合成的纳米二氧化钛已经出现纳米棒状结构,用自然界唯一的碱性多糖壳聚糖为模板剂合成的比表面积可以达432.36 m2/g.

In this article we synthesized nano-titania by the sol-gel method and hydrothermal method, respectively. In contact with the sol-gel method, the nano-titania prepared by the hydrothermal method had larger specific surface area than that prepared by the sol-gel method. The nano-titania prepared by the hydrothermal method had nano-rod, too. When the nano-titainia used chitosan as the template by the hydrothermal method, it had the largest specific surface area up to 432.36 m2/g.
