Study of nucleation and growth process of electrochemically synthesized ZnO nanostructures

Effect of H2O2 concentration on electrochemical growth and properties of vertically oriented ZnO nanorods electrodeposited from chloride solutions

“…That progressive nucleation corresponds to slow rate of nucleation, and then that nucleation will continue to take place at the surface while previous nucleation centres continue to grow. Similar results were obtained when electrodeposition ZnO nanowire a solution containing ZnCl 2 , KCl, and O 2 as precursors [30], by against an instantaneous nucleation mechanism is obtained for the layers of ZnO obtained with nitrate ions as precursors [15]. The diffusion coefficient for the Zn 2 + ions for a progressive nucleation was carried out using Eq.…”

“…ZnO with different morphologies can be prepared by various deposition techniques such as magnetron sputtering [9], chemical vapour deposition [10], pulsed laser deposition [11], spray pyrolysis [12] or thermal evaporation [13] and so on. Among all approaches, electrodeposition technique has been emerging as a competitive technique for the fabrication of metallic oxide semiconductor nanostructures with different shape and sizes [14][15][16][17].…”

Effect of electrodeposition duration on the morphological and structural modification of the flower-like nanostructured ZnO

“…Recently, electrodeposition emerged as a competitive technique for the fabrication of semiconducting thin films [28][29][30]. Very thin layers with specific composition, morphology and good adhesion between the deposited films and the substrates can be easily prepared by electrochemical techniques.…”

Effect of nitrate concentration on the electrochemical growth and properties of ZnO nanostructures

“…It is an established fact that the electrodeposition of ZnO is a versatile growth method and various nanostructures can be easily designed by this technique. Due to its simplicity and low cost, there has been growing interest in ZnO nanostructures fabricated by electrodeposition methods, and a range of morphologies and growth conditions have been reported [5][6][7][8][9][10]. These nanostructures have attracted considerable interest owing to their excellent electronic and optical properties [11][12][13].…”
