中文摘要：

二氧化钛（TiO2）光催化氧化技术是近年来的新兴技术，相对于传统的室内空气污染治理方法，TiO2光催化氧化法是通过紫外线催化，产生游离电子及空穴，进而产生极强氧化作用的羟基自由基，它可氧化分解各种有机化合物和部分无机物，使之分解成为无害的CO2、H2O，从而达到净化空气的目的。研究发现，如能将其与金属、非金属等元素掺杂，可得到更好的降解效果。该文对室内空气中主要污染物的来源、危害及TiO2光催化氧化技术在室内空气污染治理中的应用进行综述，并提出展望。

英文摘要：

It is briefly introduced that the present situation of the indoor air pollution, the main sources and adverse effects of air pollutants, and the use of TiO2 pholocatalytic oxidation technology in indoor air pollution control. TiO2 photocatalytic oxidation technology is a new technique, with cheap and quick advantage. The principle of using TiO2 in pollution control is that,with the catalysis of ultraviolet,TiO2 produces a free electron and hole, then generates a very strong oxidation hydroxyl free radicals, which can oxidize and decompose organic and inorganic compounds to produce harmless CO2,H2O. According to the development of this method, doping tectmique is an effective method which can improve TiO2 catalytic efficiency,it is also the next research focus.
