Single-pot ZnO nanostructure synthesis by chemical bath deposition and their applications

Abstract

ZnO is commonly synthesized using a many different techniques. Among them, the chemical bath deposition (CBD) technique is appealing as it is low cost and environmentally friendly, owing partly to the low temperature conditions used. An exploration of the variety of ZnO nanostructures that can be synthesized using this technique is presented in this study. ZnO fibers, nanorods, cauliflowers, nanorod balls, nanoforest, nanopencils, ellipsoids and nanotubes are synthesized using CBD by using different additives and conditions that alter the growth of the ZnO nanostructures. The application of these nanostructures in wide variety of devices is analyzed.

Photoelectrochemical Bisphenol S Sensor Based on ZnO‐Nanoroads Modified by Molecularly Imprinted Polypyrrole

“…The hydrothermal method has a number of advantages, such as inexpensive simple deposition route at low temperature with high growth rate at environmentally friendly conditions. Moreover, hydrothermal method enables large‐scale production of ZnO‐based nanostructures with different morphology such as nanoflowers, nanoneedles, nanocups, nanopetals, and powders …”

Superior adsorption performance for triphenylmethane dyes on 3D architectures assembled by ZnO nanosheets as thin as ∼1.5 nm

“…Various 3D ZnO hierarchical architectures assembled by nanorods and nanosheets have been obtained [31][32][33][34][35][36], and thickness of the thinnest constituent ZnO nanosheet is 5 nm [34]. To the best of our knowledge, the 3D hierarchical architectures assembled from ZnO nanosheets as thin as ∼1.5 nm have never been reported until now.…”

ZnO Microflowers Grown by Chemical Bath Deposition: A Low-Cost Approach for Massive Production of Functional Nanostructures

“…Therefore, under chemical bath deposition conditions, zinc nitrate and HMTA typically produce high-quality nanorods of ZnO since the equilibria established in solution promotes an anisotropic growth along the (0001) direction (for nanorods nucleated both homogeneously in solution and heterogeneously on a substrate) [5,10,12]. Variation of the precursor composition and the addition of effective complexing agents enable the synthesis of different morphology [14,15,33]. NH 4 F also dissolved in water:…”

“…All of these parameters, easily controllable, have effects on the shape and the physico-chemical properties of the grown structures [6][7][8][9][10][11]. A shining example of the development of CBD is the wide variety of zinc oxide (ZnO) nanostructures achievable via this method, spanning from nanorods to nanowalls, from nanotubes to nanoplates [8,10,[12][13][14][15]. In the last 20 years, a remarkable interest has been generated by ZnO nanostructures [16,17] because of the unique combination of material properties and nanotechnology, enabling a variety of applications, as in sensors and in electro-optical devices [17][18][19][20][21][22].…”
