Síntese e caracterização de grafeno através da carbonização e ativação da biomassa de coco babaçu em forno micro-ondas adaptado

Abstract

In this work, the synthesis and characterization of graphene-based materials were carried out using babassu coconut biomass as raw material, through a carbonization and activation process in an adapted microwave oven. The process involved the carbonization of the biomass at controlled temperatures, followed by a preliminary physical activation and a subsequent chemical activation, to obtain a carbonaceous material with an adequate structure. The characterization of the materials was done by Raman and UV-Vis spectroscopy, confirming the presence of graphene-based structures. The results indicate that babassu coconut biomass is a viable source for the production of graphene-based materials, such as graphene oxide and reduced graphene oxide, with future potential for obtaining pure graphene
