Problems solved by technology

Although there is a process for preparing nano-zinc oxide by using microwave radiation to prepare and heat nano-zinc oxide precursors, it is found in actual operation that the purity of the obtained nano-zinc oxide is not enough, which contains more undecomposed nano-zinc oxide Precursor, which seriously reduces the quality of nano zinc oxide
And the prepared nano-zinc oxide has poor performance in terms of structure and surface quality, so its effect as a photocatalyst still needs to be further improved.

Description

technical field [0001] The invention belongs to the technical field of nano-zinc oxide processing and preparation, and in particular relates to a preparation method of nano-zinc oxide with good photocatalytic performance. Background technique [0002] Nano-zinc oxide is a new multifunctional inorganic material with a particle size of about 1-100 nanometers. Due to the miniaturization of crystal grains, the surface electronic structure and crystal structure change, resulting in surface effects, volume effects, quantum size effects and macroscopic tunnel effects that macroscopic objects do not have, as well as high transparency and high dispersion. In recent years, it has been found that it exhibits many special functions in catalysis, optics, magnetism, mechanics, etc., making it have important application value in many fields such as ceramics, chemical industry, electronics, optics, biology, medicine, etc. Specificity and use of comparisons. Nano-zinc oxide can be used in ...
