The Rapid Preparation of ZnO Nanorods via Low-Temperatures Solochemical Method

Abstract

Substantial efforts have been devoted towards researching routes that provide an appropriate and simple approach for the production of zinc oxide (ZnO) nanocrystals. Here, a rapid and inexpensive solochemical method was employed to synthesize ZnQ nanocrystals through the decomposition of zinc chloride (ZnCl2) and sodium hydroxide (NaOH) at 50 degrees C, 70 degrees C and 90 degrees C. The powders were analyzed by X-ray diffraction (XRD), transmission electron microscopy (TEM) and Raman spectroscopy. The products showed high purity, nearly uniform rod-like morphology and nanometric crystallite sizes. With increasing reaction temperature, the crystallites become smaller and rounded. The Raman results reveal correlations between Raman line widths and intensities with ZnO nanorods dimensions. More specifically, the line widths are large and therefore less intense as the nanorod becomes smaller.

Effect of Polymers (PEG and PVP) on Sol-Gel Synthesis of Microsized Zinc Oxide

“…Recently, extensive progress has been made on the research front of ZnO-based micromaterials motivated by both basic sciences and potential advanced technologies [8][9][10][11][12][13][14][15][16][17][18][19][20][21]. It also has interesting chemical, acoustic, optical, and electrical properties [22].…”

Peptides with Charged Amino Acids Mitigate nZnO-Induced Growth Inhibition of Lactobacillus rhamnosus LRa05

“…As shown, the interaction of the peptide with nZnO resulted in the shift from 1531 to 1553 cm −1 (Figure 4C and Table 2), indicating that the electron cloud density of the N−H bond has been altered, forming the N−Zn structure. 24 The peak of amide band I at 1626 shifted to 1649 cm −1 and the disappearance of amide band III peak at 1341 cm −1 , indicating that the peptide bond was an important site of action. Therefore, the interaction sites of WE7 with nZnO might be the amide bond, amino group, and phenyl ring.…”
