Abstract

In recent years, the synthesis of nanoparticles has been primarily focused on metal oxides because of their large surface area and good adsorption properties. The metal oxide commonly used in industry is nickel oxide (NiO) because it can be used for various applications, such as electrodes, catalysts, and sensors, and in multiple applications ranging from electrochemical detection to energy storage and environmental remediation. The method in the process of synthesizing nickel oxide nanoparticles which are considered to produce optimal products is the sol-gel method. The sol-gel method is a chemical method for synthesizing nanostructures. The process starts from precursor molecules dissolved in water or alcohol and then converted into gels through heating and stirring with hydrolysis or alcoholysis. Then the resulting gel is dried by the appropriate method depending on the desired properties and application. The sol-gel method was chosen because it produces products with high purity without needing a lot of energy. Therefore, this review paper will discuss research on the traditional and green synthesis of nickel oxide nanoparticles using the sol-gel method with the precursor used, namely polyethylene glycol, as an agglomeration barrier, including possible improvements and weaknesses of this method.
