【正文】 納米二氧化鈦的應(yīng)用及其制備方法 摘 要 本文主要通過(guò)對(duì)納米二氧化鈦結(jié)構(gòu)及性能的介紹，引出其在各方面的應(yīng)用，特別是在環(huán)保方面的應(yīng)用。最后，從兩個(gè)不同方面來(lái)介紹納米二氧化鈦的制法。納米二氧化鈦是一種新型環(huán)境凈化材料，有板鐵礦、銳鐵礦和金紅石三種晶體結(jié)構(gòu)，具有良好的光催化性能及親水性，這也是其在環(huán)境凈化方面的應(yīng)用基礎(chǔ)，主要用于凈化水、空氣和殺菌，另外還可做建筑涂料。制備方法主要有包括兩大類(lèi)：一類(lèi)是氣相法，主要包括：TiCl4氫氧焰水解法。TiCl4氣相氧化法。鈦醇鹽氣相水解法。鈦醇鹽氣相分解法。另一類(lèi)是液相法，主要包括：溶膠一凝膠法。沉淀法，其又包括共沉淀法(液相沉淀法)和均勻沉淀法。溶膠一萃取法。水熱合成法。微乳法。關(guān)鍵字: 納米二氧化鈦、應(yīng)用、制備方法ABSTRACT This paper mainly through nanometer tio2 structure and properties of the introduction, leads to the application, especially in the environment of application, and finally, from two different aspects to introduce a method of nanotio2. Nano tio2 is a new type of environmental purification materials, plate iron ore, iron ore and rutile sharp three kinds of crystal structure, good light catalytic performance and hydrophilic, this also is the application in environmental purification based, is mainly used to purify water, air and sterilization, also can do architectural coatings. Preparation methods mainly includes two kinds: one is the gas phase method, mainly includes: 1, TiCl4 hydroxide flame hydrolysis method. 2, TiCl4 gas phase oxidation. 3, titanium alcohol salt gas phase hydrolysis method. 4, titanium alcohol salt gas phase deposition method. Another kind is the liquid phase method, mainly includes: 1, solgel gel method. 2, precipitation, and including the total precipitation (liquid precipitation) and even precipitation. 3, solgel extraction. 4, hydrothermal synthesis. 5, microemulsion methods.Key word: nanometer tio2。 application。 method of preparation 目 錄1前沿4 4 5 7 本論文選題的的意義82二氧化鈦結(jié)構(gòu)9 9 93納米TiO2的性質(zhì)10 10 10 TiO2光催化性10 Ti02光催化原理11 半導(dǎo)體性能124納米TiO2的性能及應(yīng)用12 納米二氧化鈦的性能12 抗菌功能12 廢水處理功能13 空氣凈化功能183
