Abstract
We modify and optimize a cheap, simple and effective synthesis of zinc oxide nanosized particles by electrodeposition. The core method encompasses the synthesis of ZnO product on the soluble zinc anode of the two-zinc-electrode cell emerged in aqueous NaCl. Resulting particles have the shape of cocoa fruit, thick in the middle and sharp at the edges. They have uniform shape, but broad size distributions with most of the ZnO product 1-2 µm long and 0,5-0,7 µm thick. Thus, auxiliary stabilizers are added to aqueous phase to reduce the size and narrow its distribution in the target product. Here we present the size stabilizing action of four successful stabilizers: urea, polyvinyl alcohol, Triton x-100 and Atlas G3300. All of them reduce particle size and polydispersity. An anionactive surfactant atlas is the most effective, giving an order of magnitude nanorod size reduction.
Highlights
ZnO is a semiconductor material with a direct wide band gap energy (3.37 eV) and a large exciton binding energy (60 meV) at room temperature [3]
We only briefly motivate the development of synthetic methods aiming at ZnO wurtzite nanorods by noting their significance
Earlier we found that flower-like ZnO aggregates have much higher piezoelectric sensitivity coefficients [38]
Summary
ZnO is a semiconductor material with a direct wide band gap energy (3.37 eV) and a large exciton binding energy (60 meV) at room temperature [3]. The two-electrode neural aqueous synthesis is simple, green and cheap, gives high yields and allows the current-time control of product quantity [20,30,32,34,37,38,39]. It is successfully used for the manufacture of ZnO thin films [40]. The compounds that we are testing were used earlier in different synthetical procedures aiming at ZnO: urea [47] as an alkali source together with N2H4 and as a stabilizer [48], PVA [49,50,51]. Optimization of synthetic conditions is promising, but extremely challenging with a multitude of factors to control
