光催化自洁净混凝土研究进展

Progress of research on photocatalytic self-cleaning concrete

混凝土建筑技术的进步使得作为装饰材料的混凝土在一些现代建筑中大量应用,开发自洁净混凝土能提高混凝土装饰效果并赋予了其环境净化的功能。对制备光催化自洁净混凝土所需的光催化剂的选择及其光催化机理、光催化自洁净混凝土的研究与制备、光催化自洁净混凝土对污染物的降解效果以及光催化自洁净混凝土工程应用进行的综述,并分析了其工程应用中存在的问题。

With the development of concrete building techniques,decorative concrete has been widely used in some modern buildings,to devel-op photocatalytic self-cleaning concrete and bring it to market can improve the decorative effect and give environment purification function of concrete.In this paper,the selection and reaction mechanism of photocatalyst to prepare photocatalytic self-cleaning concrete are introduced;the processing,the degradation efficiency and the practical applications of photocatalytic self-cleaning concrete materials are reviewed in details;Some problems and limitations existing in engineering application of these concrete materials are also discussed.
