纳米二氧化钛作为一种新型光催化剂、抗紫外线剂、光电效应剂等，以其神奇的功能，将在抗菌防霉、排气净化、脱臭、水处理、防污、耐候抗老化、汽车面漆等优先域显示广阔的应用前景。

随着其产品工业化生产和功能性应用发展的日趋成熟，它在环境、信息、材料、能源、医疗与卫生等优先域的技术革命中将起到不可低估的作用。

由于纳米二氧化钛电子结构所具有的特点，使其受光时生成化学活泼性很强的超氧化物阴离子自由基和氢氧自由基，攻击有机物，达到降解有机污染物的作用。

当遇到细菌时，直接攻击细菌的细胞，致使细菌细胞内的有机物降解，以此杀灭细菌，并使之分解。纳米二氧化钛不仅能影响细菌繁殖力，而且能破坏细菌的细胞膜结构，达到彻底降解细菌，防止内毒素引起的二次污染，纳米二氧化钛属于非溶出型材料，在降解有机污染物和杀灭菌的同时，自身不分解、不溶出，光催化作用持久，并具有持久的杀菌、降解污染物效果。

作为纳米材料，除了满足纳米尺寸的要求以外，还必须具备功能性和应用性。达到纳米尺度分布的纳米二氧化钛能充分地体现量子尺寸效应、表面效应、体积效应和宏观量子隧道效应，因此具有纳米粒子一系列特殊的应用特性，如抗菌、空气净化、污水净化等。

As a new type of photocatalyst, UV resistant agent and photoelectric effect agent, nano titanium dioxide will display broad application prospects in the fields of antibacterial, mildew proof, exhaust purification, deodorization, water treatment, antifouling, weathering, anti-aging, automobile topcoat and other fields.

With the development of industrial production and functional application of its products, it will play an important role in the technological revolution in the fields of environment, information, materials, energy, medical treatment and health.

Due to the characteristics of the electronic structure of nano titanium dioxide, it generates superoxide anion free radicals and oxyhydrogen free radicals with strong chemical activity when exposed to light to attack organic substances and degrade organic pollutants.

When bacteria are encountered, they directly attack the bacterial cells, causing the degradation of organic matter in the bacterial cells, so as to kill the bacteria and decompose them. Nano titanium dioxide can not only affect the fecundity of bacteria, but also destroy the cell membrane structure of bacteria, so as to completely degrade bacteria and prevent secondary pollution caused by endotoxin. Nano titanium dioxide is a non dissolution material. While degrading organic pollutants and killing and sterilizing, it does not decompose and dissolve itself, has a lasting photocatalytic effect, and has lasting sterilization Degradation of pollutants.

As a nano material, in addition to meeting the requirements of nano size, it must also have functionality and application. Nano titanium dioxide with nano scale distribution can fully reflect quantum size effect, surface effect, volume effect and macro quantum tunnel effect. Therefore, it has a series of special application characteristics of nanoparticles, such as antibacterial, air purification, sewage purification and so on.
