| 摘 要： | 以偏钛酸浆料为原料通过水热法合成了纳米管钛酸,并采用TEM,比表面积测定仪等分析手段观察其形貌和管径大小,测定了其比表面积和孔体积.同时运用正交实验法考察了反应温度、反应时间对纳米管钛酸比表面积和孔体积的影响.实验结果表明,所制备的纳米管钛酸平均比表面积高达 340m2 /g,最佳的制备工艺是:工业碱NaOH的质量分数为 25. 7 %、偏钛酸浆料的质量分数为 17. 1 %、后处理酸度为pH=1、反应温度为 120℃、反应时间为 20h.

| Abstract: | Nanotubed titanic acidwas prepared with titanic acid slurry as raw material by hydrothermal method. The titanic nanotubes were studied by TEM andsurface area measurement.At the same time orthogonal experimental method was used to study the effect of reation temperature and time on the surface area and pore volume. The results indicatethat the nanotubed titanic acid prepared by this method is of high surface area with high yield. The average specific area is 340m~2/g. The optimum conditions of preparation techniqueof nanotubes are shown as follows: the mass percentof NaOH is (25.7 %), titanic slurry is 17.1 %, posttreated pH value is 1, reaction temperatureis 120 ℃and reaction time is 20 h. |
