Graphene is one layer of graphite
WebThe theory of one atomic layer graphite (Graphene) was laid out for the first time in 1947 by P. R. Wallace. The name Graphene was mentioned for the first time in 1987 . The story and research continued, but no one could make one atomic layer of Graphene, even though very complicated experiments were carried out. WebDec 26, 2024 · This study focused on the structural investigation of few-layer graphene (FLG) synthesis from bituminous coal through a catalytic process under microwave heat treatment (MW). The produced FLG has been examined by Raman spectroscopy, XRD, TEM, and AFM. Coal was activated using the potassium hydroxide activation process. …
