摘要:因为TiO2具有良好的化学惰性、生物兼容性、吸附能力强和较强的氧化能力而且价格低廉,在催化、处理废水、净化环境、传感器的制作和化妆品等诸多领域里起到了重要的作用,人们对其的关注度也越来越高,TiO2是近年格外热门的新兴的新型功能材料。TiO2纳米管是二氧化钛的一种形式,因为TiO2纳米管是两端开孔中间中空的结构,因此它的表面区域非常特别,同时孔体积,比表面积更大,效果更好的吸附能力,表面活化能能高,而且还有良好的光催化活性。在太阳能电池、传感器、光催化等方面有重要的用途。21424
本毕业论文文从TiO2纳米管的晶型开始,之后对它的组成结构进行了简要的概述,并对其制作、负载金以后的光催化降解效率进行了分析。

Abstract:Because TiO2 is chemically inert, good biological ompatibility, strong adsorption capacity and strong oxidation capability and low price, in catalysis, wastewater treatment, purifying environment, sensor production and cosmetics and otherfields has played an important role, people more the attention degree and TiO2 in recent years, particularly new type of functional materials. TiO2 nanotubes is a form of it, because the TiO2 nanotubes have a hollow tubular structure so that ithas a surface area and pore volume of special, bigger specific surface area, theadsorption ability is more powerful,surface activation energy can be high,but also exhibited a higher photocatalytic activity. Has important applications in solar cells, sensors,photocatalysis etc..
This paper starts from the crystalline TiO2 nanotubes, formed after the structure is briefly summarized, and the production efficiency, the load of photocatalytic degradation of the gold is analyzed.
