Application of photocatalytic technology in environmental safety

With the environmental safety becoming the research focus, water environmental security, as an updating research direction has also been the concern. Nano-titania photocatalysis can prevent environmental pollution from the sources and ensure the fundamental productions in the industry. The applications of nano particle photocatalytic technology in environmental safety are reviewed. Emphasis is put on the applications of nano-titania photocatalytic technology in wastewater treatment, and the latest achievements in scientific research of nano particle photocatalytic technology in wastewater treatment are given. Besides, it is also pointed out that the technology of using nano-titania as photocatalyst has some obvious disadvantages in the actual treatment process of environmental safety. Lastly, the development trend of photocatalytic technology is discussed.
