摘要/Abstract

摘要： 以明胶为分散剂采用溶胶-凝胶法制备了纳米晶TiO₂粉末.通过XRD、TG-DTA、AFM、N₂吸附-解吸等手段,考察了明胶对TiO₂煅烧过程中相变和平均粒径的影响;用光催化降解甲基橙检测了明胶用量对样品光催化活性的影响.结果表明:明胶的存在抑制了TiO₂由无定形向锐钛矿的相变,降低了锐钛矿向金红石的相变温度;同时,TiO₂纳米晶的平均粒径也随明胶用量的增加而减小.600℃煅烧样品的光催化活性随明胶用量的增加而提高;800℃煅烧样品在m_G:m_TBOT(明胶与钛酸四丁酯的质量比)=1:8时,具有最高的光催化活性.

关键词: 明胶, 二氧化钛, 相变, 平均粒径, 光催化活性

Abstract: Nanocrystalline TiO₂ powders were prepared with gelatin dispersants by sol-gel method.The effects of gelatin on phase transformation and average particle sizes of nanocrystalline TiO₂ during calcination were investigated by the means of XRD,TG-DTA,AFM,and N₂ adsorption-desorption.Moreover,the effects of gelatin dosage on photocatalytic activity of samples were evaluated from an analysis of the photodegradation of methyl orange.The experimental results indicate that the gelatin has effects of inhibiting phase transformation from amorphism to anatase and decreasing the anatase-to-rutile transformation temperature,and the average particle size of nanocrystalline TiO₂ decreases with increasing the gelatin dosage.The photocatalytic activity of samples calcined at 600 ℃ increases with increasing gelatin dosage.As for samples calcined at 800 ℃,the highest photocatalytic activity was obtained when m_G:m_TBOT(mass ratio of gelatin to tetrabutyl titanate)=(1:8.)

Key words: gelatin, titanium dioxide, phase transformation, average particle size, photocatalytic activity
