Additionally, the incorporation of an elevated temperature of 75°C further intensifies the reaction rate, which enhances the production efficiency and reduces the overall latency. This method presents a simple and environmentally sustainable approach for graphene synthesis, highlighting its potential for green chemistry applications. Characterizations like XRD, Raman spectroscopy, SEM, EDS, TEM, and UV-Visible studies confirm the formation of good-quality graphene, accompanied by the least number of layers of graphene. Our findings demonstrate a high production yield and noticeably large crystallite size, which makes it a great contender for energy storage and sensor applications. This study provides valuable insights into advanced materials synthesis, laying the groundwork for future research and the development of applications-oriented technologies. https://jams.hsu.ac.ir/article_243917_b8bd699812d2616e890dffaf21b56f46.pdf
