Progress in the application of ozonation catalyzed by nano-catalysts.

The application of homogeneous nano-catalysts in catalytic ozonation was reviewed and the technical mechanism of catalytic ozonation was discussed. There are many types of catalysts in actual production. Nano-catalysts have been widely concerned and applied due to their large specific surface area, many active sites and high catalytic efficiency. The different materials such as metal, metal oxide nano-catalyst, perovskite nano-catalyst and carbon-based nano-catalyst are summarized, and the existing treatment effects of nano-catalyst applied in catalytic ozonation are introduced. The main disadvantages and corresponding countermeasures of nano-catalysts are pointed out, and the future development direction is prospected. In order to provide reference for the application of nano-catalyst ozonation in practical engineering. [ABSTRACT FROM AUTHOR]
