Unconventional eco-friendly synthesis of graphene and its electrochemical analysis

In response to the growing demand for sustainable graphene synthesis methods, traditionally characterized by harsh conditions and prolonged processing, we present an innovative approach. Here, graphene is synthesized utilizing melaleuca alternifolia, a natural resource, under mild conditions of cold plasma. This method not only aligns with the increasing need for environmentally friendly processes but also boasts efficiency, producing graphene within seconds. Our investigation employs various analytical techniques, including Raman spectroscopy, confirming the successful synthesis of graphene. The distinctive peaks identified in the spectroscopic analysis validate the high quality of the graphene material produced. Beyond synthesis, our study delves into the electrochemical properties of the synthesized graphene. Rigorous testing with real biomolecules reveals enhanced current peaks, underscoring the potential applications of graphene in the realm of electrochemical sensing. This work contributes to advancing sustainable and efficient graphene synthesis while exploring its promising properties for practical applications.
