The nowadays world fast technological development has raised the demand of electrical/mechanical energies to levels well above the capacity of their generation exclusively from sustainable/renewable sources. This implies that significant fractions of usable energies have to be derived from fossil fuels, whose consequence has strong negative impacts over the environment, one of them relate…
The reactions involved in the carbon dioxide and water electrochemistry can be utilized in electrochemical energy conversion and storage devices. The coupling of carbon dioxide electro-reduction and water electro-oxidation can be used in electrochemical devices of fuel production. On the contrary, the coupling of the electro-oxidation of molecules with high hydrogen content and the oxygen…
The goal of the present project consists of the study of electrocatalytic processes taking place in energy conversion and storage systems, particularly the ones involving reactions in fuel cells, including bio-active electrodes. Attention will be paid to the study of the oxygen reduction reaction and of the oxidation of alcohol molecules and hydrogen deliberately contaminated with traces …
This work aims at studying the ethanol oxidation electrocatalysis. This reaction, that takes place at the anode of direct ethanol fuel cells, will be investigated on electrocatalysts formed by Pt monolayers. The electrocatalysis of the total oxidation of the ethanol to CO2 involves the deshydrogenation step, the C-C bond breaking, and the oxidation of the adsorbed CO, which is a product o…
Bulk or nanostructured Sn electrocatalysts for the CO2 reduction to formic acid (or formate ions) are advantageous due to its abundance and low toxicity. The catalytic reduction of CO to HCO2 requires a formal transfer of a hydride, which originates from water activation. However, on metallic Sn surface, the water activation is kinetically limited. In natural catalysts, sulfur atoms are r…
Copper is the only metal capable of promoting the electroreduction of CO2 to hydrocarbons. Experimentally, however, it is noted that copper has a highly dynamic behavior. Since this aspect is unavoidable, its use for the benefit of stability for RECO2 is possible. This can be achieved using electrocatalysts formed by copper ions coordinated by water insoluble ligands, thus, allowing the r…
The consumption of fossil fuels is the main cause of climate change, resulting in global warming due to the accumulation of greenhouse gases in the atmosphere, especially carbon dioxide (CO2). The conversion of CO2 into carbon-based fuels and raw materials allows the storage of energy ina renewable way and contributes to the reduction of greenhouse gas emissions. In this context, the elec…

Photoelectrolytic cells are important alternatives to hydrogen (H2), since they are operated with renewable fuels and with solar energy. H2 production is relevant because it can be used as fuel in fuel cells of the PEMFC type (polymer electrolyte membrane fuel cell). Photoelectrochemically shaped, the fuel is photo-electro-oxidized without anode and protons (for acid electrolytes) are ele…
The electrocatalytic reduction of carbon dioxide (CO2) is a key theme on the global research concerning stock and energy conversion. Due the multidisciplinary of the problem, these investigations apply concepts from different sciences. For instance, the functionalization of metallic surfaces by organic molecules is considered an elegant and efficient strategy to modulate the catalytic act…
The increasing rise in the atmospheric CO2 concentration (greenhouse gas and climate change) has encouraged the search for methods to fix this pollutant. In recent years, photo-/electro-reduction of CO2 has been highlighted as promising; beyond the consumption of this gas, it still produces fuel, or reagents such as hydrocarbons, alcohols and carboxylic acids. Several materials have been …

The development of electrochemical devices that promote the regenerative electro-conversion between chemical and electrical energy is of great importance for a sustainable energy scenario. The unitized regenerative fuel cells (URFC) are examples of such devices, which require bifunctional electrocatalysts, i.e., active materials for hydrogen evolution/oxidation and for the oxygen evolutio…
Direct Ethanol Fuel Cells (DEFC) are an important type of virtual hydrogen fuel cell. This is mainly because ethanol has a high hydrogen content or high energy density, low toxicity, and possibility to be produced in large amounts through the fermentation of biomass, offering an interesting economic viability. The total electro-oxidation of ethanol to CO2 releases 12 electrons per molecul…
Passive fuel cells fed with liquid fuels, such as hydrazine and borohydride ions in the anode, and air in the cathode (also called hydrazine or borohydride/air batteries) are promising alternatives as power sources. This is due to their high energy density, autonomy, and easy fuel supply, compared to lithium ion batteries that have high energy density, but with limited autonomy. The hydra…
