Zinc oxide because of the proliferation of gas through the faster, it is an excellent catalyst. Zinc oxide because of its small size, large specific surface area, surface bond and the different particles within the surface atoms, such as coordination failure, resulting in an increase in the surface of the active sites formed uneven atomic level, increase the reaction surface, Zinc oxide catalytic activity and selectivity far greater than traditional catalysts.
Zinc oxide is a good photocatalyst. Harmful organic substances in water such as chlorinated organic compounds, pesticides, surfactants, pigments, water treatment technology with the current is very difficult to fully remove, and Zinc oxide as a photocatalyst can decompose organic matter. Study on the surface of Zinc oxide particles in the reaction rate is the ordinary zinc oxide particles of 10-1000 times compared with ordinary particles, which caused almost no light scattering, and there is a large surface area and a wide energy band, it was that is a very promising one photocatalyst.
