“…Until now, various techniques have been used for the preparation of ZnO particles, e.g. high-temperature hydrothermal synthesis, [5][6][7] laser heating [8] or the high-temperature decomposition method. [9] However, the high-temperature methods are unfavourable because of high energy consumption.…”

The anodic behaviour of zinc was investigated in ethanol solution containing LiCl and water. Zinc was polarised by using cyclic voltammetry and chronoamperometry techniques. During the course of the dissolution of zinc, a colloidal suspension of ZnO nanoparticles was obtained in 0.1 M LiCl/ethanol solutions that contain H 2 O. The suspension is formed only if water is present, and the rate of the process depends on the water content. Moreover, the concentration

“…Table 1 lists the major Raman scattering peaks of the ZnO, Ca(OH) 2 , BM-ZnCa powders and CP-ZnCa powders. There were three major Raman peaks for ZnO, i.e., at 334, 385, and 437 cm -1 [22][23][24]. However, there were four major Raman peaks for Ca(OH) 2 , namely, at 288, 365, 436, 720 and 1,092 cm -1 [22].…”

Nano-sized calcium zincate powders used as active materials for a secondary Zn electrode were prepared by a chemical co-precipitation method. The properties were studied by thermal gravimetric analysis (TGA), micro-Raman spectroscopy and nitrogen adsorption-desorption experiments. The secondary Zn electrodes using chemical coprecipitation calcium zincate powders (CP-ZnCa) and ballmilled calcium zincate powders (BM-ZnCa), were examined and compared. The electrochemical performance of the secondary Zn electrodes was systematically investigated by cyclic voltammetry and galvanostatic charge/discharge measurements. It was demonstrated that the electrochemical properties of the secondary Zn-pasted electrode using CPZnCa powders were greatly improved, as compared with conventional secondary ZnO electrodes. The results indicated that secondary Ni-Zn batteries using CP-ZnCa powders exhibited a better charge/discharge property and a longer lifecycle performance, compared with those based on ball-milled ZnO + Ca(OH) 2 (BM-ZnCa) powders.

“…We have systematically investigated [1][2][3][4][5][6][7][8][9] the impact of different experimental conditions on the properties of ZnO powders. In continuation of these works we have studied the impact of experimental conditions on the formation of ZnO fibers using the electrospinning method.…”

Abstract. The influence of experimental conditions on the formation of ZnO fibers by electrospinning has been investigated. The electrospinning of a viscous suspension containing polyvinylpyrrolidone and zinc acetate in C2H5OH/H2O produced very long fibers (several hundred μm). Upon calcination a thin deposit of precursor fibers at 400 or 500 °C for 1 h the fibers consisting of ZnO nanoparticles were obtained. On the other hand, ZnO fibers were not obtained upon heating a thick deposit of precursor fibers at 600 °C for 6 h. At all three heating temperatures (400, 500 or 600 °C) ZnO nanoparticles with a gradual increase in size were produced. The Raman spectrum of ZnO nanoparticles formed at 600 °C showed additional bands which were assigned to graphene oxide. It was suggested that in the thick deposit the organic component did not burn out completely, i.e., the residual carbon (graphite) transformed into graphene oxide for the experimental conditions applied.
