由于光催化氧化技术具有效率高、无二次污染、无毒等优点,其是环境科学与技术领域的热点研究方向之一,但多年一直处于研究试验阶段,其在工程应用中非常罕见。如何将光催化氧化技术应用到环境污染治理工程中是该领域研究重点及难点。纳米光催化材料被称为环境友好材料,该文主要介绍了光催化氧化技术的发展史、纳米光催化材料特点、其在环境污染治理中的研究进展,最后分析该研究领域存在的问题并提出前景方向。 As photocatalytic oxidation technology with high efficiency, no secondary pollution, non-toxic, etc., which is one of the hot spots in the field of environmental science and technology research, but for many years has been in the research and experimental phase, which is very rare in engineering applications. How to apply photocatalytic oxidation technology to environmental pollution control project is the key and difficult point in this field. This paper mainly introduces the development history of photocatalytic oxidation technology, the characteristics of nano-photocatalytic material, its research progress in environmental pollution control, and finally analyzes the existing problems in the field of research and puts forward The future direction.
