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 electro-oxidation reactions of small organic molecules are studied under different catalysts and by means of techniques so that one can know the reaction mechanisms and the reaction intermediates. These reactions have some characteristics in common in their reaction mechanisms that are responsible for making the electro-oxidation processes susceptible to dynamic instabilities. The glu…
Despite its complexity, the living systems present, in numerous processes for their maintenance, certain kinetic and thermodynamic specificities. In these, the natural chemosmotic and electrochemical gradients as driving forces is coupled to various metabolic pathways by enzymatic systems. Considering this universal characteristic of known life, it was developed in the last 30 years one o…
Electrocatalysis is the heart of the electrochemical energy conversion, in order to optimize rate, selectivity, energy and stability of certain electrochemical reactions - such as oxygen reduction (ORR), oxygen evolution (OER), and hydrogen evolution (HER) - proper catalysts have to be developed and optimized. Precious noble-metals (e.g. Pt, Ru, Ir, and Pd) supported on carbon nanomateria…
Among the various proposals to replace the current energy matrix based on fossil fuels, with renewable and sustainable sources, there are the so-called fuel cells, devices that directly convert chemical energy into electricity. Although hydrogen is one of the most viable substances for use in fuel cells, its production and storage are still a challenge. Other alternatives extensively stud…
Under a given set of experimental conditions, potential (or current) oscillations can be observed during the electro-oxidation of small organic molecules, such as methanol, formic acid, ethylene glycol and glucose, for example. Variables like identity of the organic molecule, temperature, applied potential, nature and superficial state of the catalyst, supporting electrolyte, etc., direct…
The electrooxidation reaction of glucose is used in different applications and currently its use has been highlighted in fuel cells, since, it is one of the carbohydrates present in greater quantity in the nature and in the human body, being sustainable and friendly to the environment. On polycrystalline platinum and gold electrodes, the mechanism of glucose oxidation occurs in three stag…

The development of efficient and reliable energy conversion devices depends on the design of more active and highly stable catalysts. Given that the current control over catalytic activity is more advanced than our understanding of the stability of surface atoms, it is paramount to establish functional links between activity/stability to enable synthesis of new materials with tailored pro…
In the recent years investigations on the oxidation of small organic molecules (SOM) has been done extensively and under various conditions, where the general focus lied on formic acid, because of its model character and its possible application in fuel cells. Since Capon and Parsons published their articles about the formic acid oxidation on platinum (Pt), their dual-pathway mechanism is…
Recent findings show that interesting behavior can be observed when electro-oxidizing mixed fuels. In the literature there is a contradiction on the nature of the interaction of formic acid and hydrazine over platinum electrodes, during their electro-oxidation. It is stated that this process should occur additively, without mutual interference. Recently, we found that this interaction occ…
