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…
The development of stable and highly active electrocatalysts is essential to obtain clean and efficient energy conversion systems, such as fuel cells. Currently, Fe-N-C type electrocatalysts, which are iron atoms anchored on a nitrogen-doped carbon matrix, are promising as a substitute for platinum on the cathode, although, even with desirable activity, these materials face the challenge …
The advancement in effective technologies for the conversion and storage of clean energy plays a crucial role in building a sustainable society. In this context, the electrocatalytic reduction of carbon dioxide (RECO2) is an attractive process due to its potential to generate raw materials and renewable energy. Among all metals, copper stands out for its ability to directly convert CO2 in…
The development of efficient technologies for energy conversion and storage fits as a fundamental element for the establishment of a sustainable society. In this context, the electrocatalytic reduction of carbon dioxide (RECO2) emerges as a very attractive process, since it allows the storage of energy by the conversion of electrical energy into chemical. On copper-based electrocatalysts,…
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…

Manganese-based oxides have emerged as promising catalysts for electrooxidation reactions, such as water and organic molecules oxidation for green hydrogen generation. Due to their redox properties, especially in higheroxidation states (Mn(IV) or even Mn(VII)), exhibit excellent catalytic activity foroxidation. Additionally, manganese oxides present unique stability in acid electrolytes.H…
The electrochemical reduction of carbon dioxide (CO2R) constitutes a promising process that can both contribute to reduce net CO2 emissions and be an alternative/sustainable method to produce valuable chemicals. However, the use of CO2R in large scale is hampered by the high required overpotentials and poor selectivity. Thus, efforts have been made towards the development of more active, …
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…
