Abstract

The present project aims to synthesize amorphous carbon from sugarcane bagasse, targeting its application in the electrochemical reduction of carbon dioxide (CO2). The research focuses on the calcination and activation of sugarcane bagasse, an abundant by-product of the sugar-alcohol industry, to produce activated carbon with suitable electrochemical properties for use in converting CO2 into valuable chemical products. The project addresses the optimization of variables such as temperature, time, and activator concentration during the calcination process, with the goal of maximizing CO2 conversion efficiency. The materials obtained will be characterized using physical and electrochemical techniques to identify the best parameters for the synthesis of activated carbon. Additionally, the research will investigate the products formed during the electrochemical reduction of CO2, including compounds like formic acid and methanol, and the optimal conditions for their production. The proposal seeks to contribute to the mitigation of CO2 emissions and promote the sustainable use of agricultural residues, offering an innovative approach to developing technologies that can help reduce atmospheric CO2 concentrations.
