“…The issue of photocatalytic activity has received considerable critical attention, and the photocatalytic performance of ZnO catalysts is closely related to the exposed surfaces of samples. Although the control of morphology has seen much progress in the past few years, it remains the focus of research in the nanotechnology field [10][11][12].…”

Zinc oxide (ZnO) possesses superior chemical and physical properties so that it can occupy an essential position in the application of nanostructures. In this paper, ZnO nano-rod arrays were synthesized by a simple one-step hydrothermal approach with the assistance of cetyl trimethyl ammonium bromide (CTAB). Exposure of the {0001} facets could be controlled by adjusting the amount of CTAB and the maximum exposure of the {0001} facets of ZnO nanorods is obtained at 1.2 g of CTAB. The photocurrent, EIS, and PL measurements support the facile charge transfer with minimum recombination of the photogenerated excitons of the ZnO nano-rod arrays obtained at 1.2 g of CTAB. Consequently, the obtained ZnO nano-rod arrays at the optimal CTAB of 1.2 g exhibit an excellent photocatalytic degradation rate of 99.7% for rhodamine B (RhB), while the degradation rate of RhB by the ZnO obtained without CTAB is only 35%.

“…Nowadays there is a multitude of synthetic methods to obtain ZnO. To name a few, vapor-phase transport [23], sol electrophoretic deposition [24], hydrothermal/solvothermal growth [3,16,25], arc discharge [26], chemical bath deposition [12,27,28], or electrochemical deposition [29][30][31] (both anodic [32][33][34] and cathodic [35,36]). They differ in their approach, cost, and ultimate results.…”

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.

“…Moreover, surface modifiers that are organic molecules decompose at high reaction temperatures. Although methods for controlling the morphology of fine particles such as metals [1,8,9] and metal-oxide inorganic [2,4,10] compounds have been studied widely, there have been few such studies of metal nitride compounds [11]. This study concerned control of the morphology of metal nitride compounds.…”

“…To elicit high performance from inorganic crystals with respect to their catalytic [1][2][3] and photonic properties [4][5][6], it is important to understand the chemical conditions on the crystal surface and to control the crystal planes. Investigating the relationship between the crystal surface and crystal functionality is facilitated with the use of fine particles.…”

My group developed a simple method to prepare copper nitride fine particles from copper carboxylate in a solvent of long-chain alcohols without the use of high temperatures or high pressures. By selecting copper acetate or copper decanoate as the copper source, my group demonstrated that the morphology of the copper nitride fine particles varied between cubic and plate-like, respectively. Although a hypothesis was proposed to explain the influence of the length of the alkyl chain on the copper decanoate, it is uncertain how much the chain length influences the shape of the fine particles.In this work, I demonstrated the effect of the length of the alkyl chain on particle shape by preparing fine particles from a series of copper sources with different alky chain lengths and characterizing the particles with x-ray diffractometry (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The main findings were as follows: (1) the fine particles were plate-like when the alkyl chain length exceeded 5; (2) the aspect ratio of the plate-like particles increased as the alkyl chain length increased; and (3) growth of the (110) and (111) planes of the copper nitride crystal were selectively inhibited.
