Synthesis and characterization of a micro scale zinc oxide–PVA composite by ultrasound irradiation and the effect of composite on the crystal growth of zinc oxide

Effect of anion on the homogeneous precipitation of precursors and their thermal decomposition to zinc oxide

“…ZnO finds applications in optoelectronics [1,2], UV lasers [3], spintronics [4], gas sensors [5], varistor ceramics [6], catalysis [7], H 2 S removal [8], solar cells [9], etc. Synthesis of ZnO with different morphologies has been carried out by various researchers using different methods such as chemical vapour deposition [10], physical vapour deposition [11], oxidation of metal [12], decomposition of organometallic precursors [13], sonication [14], spray pyrolysis [15], microwave heating [16], combustion synthesis [17], sol-gel processes [18], hydrothermal/solvothermal methods [19], using ionic liquids [20], homogeneous precipitation [21][22][23][24][25], and wet chemical method [26]. Among the above methods, homogeneous precipitation has its own merits compared to the other methods.…”

Dependence of the microstructural properties of ZnO particles on their synthesis

“…Inubushi et al [22] investigated the mechanism of the formation of nanosize ZnO particles through a reaction between Zn(ac) 2 and NaOH in ethanol. In preparing nanosize ZnO particles researchers were also using: (a) microemulsion synthesis [23], (b) sonochemical synthesis [24,25], (c) precipitation from alcoholic media without NaOH or LiOH addition [26], (d) synthesis via an aqueous acetate-citrate gelation [27], or (e) mechanochemical processing [28].…”

Growing ZnO Crystals on Magnetite Nanoparticles

“…One such method is to grow ZnO from an aqueous solution at temperatures below 100 8C. The mild conditions of this synthesis allow the growth of ZnO by using surfactants [34±36] and diblock copolymers, [37,38] as well as the growth of ZnO on self-assembled monolayers (SAMs). [39,40] It was also found that diblock copolymers could play an important role in determining the morphology of CaCO 3 [41,42] and BaSO 4.…”
