Abstract
In this study, the synthesis and electrochemical performance of a zinc oxide/copper oxide/graphitic carbon nitride ZnO/CuO/g-C₃N₄ composite for energy storage applications were investigated. The synthesis was carried out using a multi-step process, where ZnO/CuO was prepared via co-precipitation, and g-C₃N₄ was synthesized through thermal polymerization. Fourier-transform infrared spectroscopy (FTIR) revealed the presence of metal-oxide bonds and carbon-nitrogen functional groups, verifying the successful integration of g-C₃N₄ into the ZnO/CuO system. UV-visible absorption studies exhibited a red shift and a broader absorption band in the ZnO/CuO/g-C₃N₄ composite, indicating enhanced optical properties, which are favorable for energy storage applications. Furthermore, cyclic voltammetry (CV) measurements demonstrated superior capacitance and excellent rate capability, achieving a specific capacitance of 253 F/g at a scan rate of 10 mV/s. The combined structural, optical, and electrochemical properties of the ZnO/CuO/g-C₃N₄ composite underscore its potential as an advanced material for energy storage applications.
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.
