| 中文摘要: |
| TiO2 光催化剂因其利用可持续的太阳光进行光催化反应,在环境保护、医疗卫生等领域具有潜在的应用价值,近年来引起了研究者的广泛关注。 目前,颗粒状 TiO2 催化剂获得了一定的实际应用,但在液相中使用后需要回收,不仅增加了工艺的复杂性,而且提高了设备等成本的投入。 负载型催化剂和涂层技术是将 TiO2 固定在载体上,可有效避免颗粒状催化剂难回收的问题。 在众多涂层制备技术中,热喷涂技术可快速高效大面积地制备 TiO2 光催化涂层,且涂层机械性能优异,喷涂成本低廉,因而使 TiO2的工业化制备和应用更具前景。 综述了近年来国内外制备 TiO2 涂层常用的传统热喷涂技术、改进后的液相热喷涂技术和冷喷涂技术,并论述了影响 TiO2 光催化性能的材料相组分、涂层结构和元素掺杂等因素,总结了相应的性能改进措施,指出了目前 TiO2 光催化涂层的应用研究存在的问题和研究方向。 |

| Titania is of increasing interest due to its using sustainable sunlight to drive photocatalytic reaction and its potential 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 complexity, but also the cost of equipment. Supported catalysts and coating technology could overcome the difficulty in the recycling of granular 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. |
