Structural, optical, and dielectric properties of copper-doped ZnO nanorods prepared by modified sol-gel process
In the current research work, Copper doped ZnO (Zn1-xCuxO) nanorods photocatalyst was established using a simple modified sol-gel protocol. The shape of the nanomaterial was found to be crucial for both optical response and photocatalytic activity. However, the nanorods present a 2D direction which exalts the intrinsic properties of the photocatalyst. Triethyleneglycol (TREG) was used as a solvent which is believed to be the responsible parameter that leads to preparing Cu/ZnO with this important shape. The photocatalyst after that was characterized in terms of structure, microstructure and optical absorption. The optical behavior of Cu/ZnO photocatalyst was more studied by dielectric conductivity and impedance investigation. The XRD measurements reveal the formation of ZnO wurtzite structures. Electronic microscopy images confirm the formation of the desired nanorods with nanometric size. The photodegradation activity of the Cu/ZnO photocatalyst exhibits high performance compared to pristine ZnO. The mechanism of this behavior was discussed and improved compared to previous works.
期刊介绍：
The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
