Abstract

um processo para a preparação de grafeno reduzido que compreende as etapas de: fornecer uma grafite expansível intercalada com grupos contendo oxigênio; aquecer a grafite expansível sob condições suficientes para provocar a expansão da grafite expansível e formação de uma grafite expandida compreendendo grupos contendo oxigênio; e colocar em contato a grafite expandida com monóxido de carbono para reduzir pelo menos uma parte dos grupos contendo oxigênio e formar uma grafite expandida reduzida que compreende uma matriz de grafeno reduzido. o processo da invenção permite que grandes volumes de grafeno de alta qualidade sejam produzidos.
