Synthesis of Zinc Oxide Powder by Hydrolysis of Bis(acetylacetonato)zinc(ii) in Aqueous Solution

Abstract

Pure and fine powder of zinc oxide was prepared by hydrolysis of bis(acetylacetonato)zinc(II) in methanol–water mixture. A significant difference in the particle shape was observed by TEM between ZnO powders prepared at 25 and 80 °C.

Physico-chemical characterization and photocatalytic activity of zinc oxide prepared by various methods

“…Among all the factors, crystallinity and surface area which depend on the method of preparation are regarded as important factors for determining photocatalysis. ZnO powder can be prepared by various methods which include alkali precipitation [22][23][24], thermal decomposition [25], hydrothermal synthesis [26], organo-zinc hydrolysis [27], spray pyrolysis [28] and using microwave irradiation [29].…”

Submicrometer zinc oxide particles: Elaboration in polyol medium and morphological characteristics

“…9 In order to prepare inorganic compounds via precipitation from a liquid phase, solvents as polyols offer two interesting properties: owing to their high dielectric constants, they act as solvents that can dissolve inorganic compounds and, owing to their relatively high boiling points, they offer a wide operating-temperature range (from 25 °C to boiling point) for preparing inorganic compounds at relatively low temperature. Accordingly, the preparation of monodisperse zinc oxide particles with submicrometer size has attracted much attention.…”

Self-Assembly of ZnO: From Nanodots to Nanorods

“…Recently, rodlike semiconductor and metal nanoparticles have attracted considerable attention. There are, however, only a few examples reported where those nanorods could be prepared in a controllable manner using evaporation or colloido‐chemical techniques 8–14. Materials such as ZnO, Co, Au, and CdSe were used for the rods.…”
