Abstract

The production of sustainable and renewable fuels for energy conversion is vital for designing green technologies to supply the energy needs of the population. In this work, bioethanol was obtained from Salicornia bigelovii as a salt-tolerant plant watered with seawater, converting it in an interesting sustainable energy source for clean and renewable technologies, such as fuel cells. Thus, Bioethanol (BioEOR) and ethanol (EOR) electro-oxidation reactions were evaluated using polyaniline (PANI) as a co-support in Pd/carbon paper electrodes in alkaline medium (0.3 M KOH). PANI was growth electrochemically on carbon paper (PANI-T) for the further electrodeposition of Pd on both, carbon paper (T) and PANI-T. Physicochemical characterization by XRD, TEM, EDX mapping, and XPS indicated that PANI promoted differences in the properties of Pd/PANI-T compared to Pd/T as the reference material. It decreased crystallite and particle sizes to 8.29 nm and 15
