Abstract

The overuse of non-renewables resources in the last decades has generated negative consequences for the society, which have boosting the search for mitigating the damage caused in the environment. Aiming to contribute to the expansion of the strategies to control the pollutants in the environment thought the development of low-cost technologies, the mean goal of present work is to develop active materials with high thermic resistance and suitable specific area to adsorption and impregnation of metals. In this regard, it was studied three different routes of treatment of the biocarbons. The biocarbons materials were characterized by infrared spectroscopy (IR), Raman spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric analysis (TG), and Brunauer–Emmett–Teller analysis (BET). The three different strategies of treatment resulted in changes in the carbonaceous structure of the biocarbon, resulting in suitable characteristics for support material for catalysts, such as activities sites with negative charge to promote the attachment of the metals on the carbon surface. It was also observed the enhancement of the specific surface area, that ranges from 341,4 to 749,7 m2 g-1, changes of D and G band of carbon and high temperature resistance, which promote catalytic reactions with catalyst loss.
