Resumo: The present work deals with a new methodology to produce a sustainable carbon material through a simple synthetic route, and its performance as Ni-based electrocatalyst support. Such porous carbon was easily synthesized from the raw Kraft black liquor, a by-product rich in lignin, by chemical polymerization in alkaline medium with a nickel source and subsequent activation by CO2. Nickel nanoparticles were homogeneously distributed in the samples, as revealed by STEM images. XPS analyses and BET method indicated the presence of Ni species in the synthesized material and a micro-mesoporous structure, respectively. The electrochemical characterization in NaOH and NaOH+ethanol solutions showed that the as-prepared material has the relevant potential to be applied as electrocatalyst for Ethanol Oxidation Reaction (EOR) in alkaline medium.
