Abstract

Ethanol and biodiesel are renewable fuels of high importance for the Brazilian energy matrix, where they represent almost half of the domestic supply of energy from renewable sources. The production of biodiesel has been growing steadily over the years and generated glycerol as a by-product, another renewable energy source that can also be used as a precursor for the synthesis of high value compounds. In this scenario, the aim of this PhD project is to investigate the cogeneration of energy and high added value products of the electrooxidation of glycerol. Thus, we will synthesize shape-controlled platinum nanoparticles and modify their surface with p-block atoms. Several in situ techniques will be used in order to perform fundamental studies of these catalysts to understand the relationship between their performance and the products and reaction intermediates formed, as well as their physicochemical properties. The performance of the catalysts will be investigated in conventional electrochemical cell and the most promising catalysts will be evaluated in microfluidic fuel cells, where we will measure the power, the oxidation products generated during the cell operation, the catalyst structural stability and the stability of the cell performance.
