설명

일반 설명

Zinc acetate dihydrate ((CH₃COO)₂Zn · 2H₂O) is hydrated form of zinc acetate. It is bidentate and has covalent character. It is commonly used as a zinc precursor in preparation of zinc oxide nanopowder.

애플리케이션

Zinc acetate dihydrate can be used:

• As a zinc precursor in the synthesis of ZnO nanowires by thermal decomposition method without any catalyst.
• As a zinc source in the synthesis of ZnO nanoparticles (zinc oxide nanoparticles) with sodium hydroxide by hydrothermal growth method.
