Due to the extremely strong surface activity of nano TiO2, it is easy to form large-sized agglomerates, which affects the practical application. Therefore, it can be modified from the aspects of improving the photocatalytic degradation efficiency of TiO2, changing the dielectric constant and surface activity of TiO2. There are two ways of combining surfactants with TiO2: one is physical adsorption...

Nano zinc oxide is a fine inorganic material with a particle size between 1nm and 100nm. Zinc oxide usually exists in the form of wurtzite, with four oxygen atoms surrounding the zinc ion, forming a thermodynamically stable tetrahedral structure. Due to the changes in the crystal structure and surface electronic structure of nano-zinc oxide, nano-zinc oxide has the characteristics of surface effec...
