Research Progress in Thermal Spray Fabrication of Titania Photocatalytic Coatings
摘要
Abstract
ABSTRACT:Titania is of increasing interest due to its using sustainable sunlight to drive photocatalytic reaction and its potential <br> application in environmental protection, health care and so forth. At present, particle-type titania catalyst has been putting into practice, but those catalyst powders servicing in liquid phase always need recycling process, which increases not only the complexi-ty, but also the cost of equipment. Supported catalysts and coating technology could overcome the difficulty in the recycling of gran-ular catalysts through immobilization of TiO2 on various supports. Among numerous coating preparative techniques, thermal spray has the ability to prepare large-area coating with high mechanical performance quickly and efficiently at a low cost, which shows a bright prospect in the industrialization of titanium dioxide. This paper summarized the common thermal spraying techniques, the modified liquid thermal spray and cold spray technologies used to elaborate TiO2 coatings in China and foreign countries in recent years, and discussed the influencing factors on the photocatalytic performance, such as the material phase composition, coating structure, element doping and so on. The corresponding performance improvement measures were summarized, and the existing problems of current researches on TiO2 photocatalytic caotings and future research direction were pointed out.关键词
