Safeguarding Brazilian society's increasing demand for energy and meeting the target for CO2 emissions reduction mandates investments in renewable energy sources and low carbon technologies. Toward tackling such a challenge, the United Kingdom has a mature and extensive research infrastructure via the Hydrogen and Fuel Cell Research Hub. Fuel cells are increasingly important electrochemic…
The FAPESP - Shell Research Centre for Greenhouse Gas Innovation aims to be a world-class Centre for advanced studies with a focus on innovation towards sustainability and mitigation of greenhouse gas emissions. The Centre complements Fapesp's experiences in supporting high-level scientific research and technology development towards these fields. It aims to establish a world-class Centre…
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 anthropogenic carbon dioxide (CO2) emissions are not balanced by the bio-cycles, leading to this gas accumulation and, consequently, affecting climate change. The use of biomass as a fuel helps to minimize this matter since the generated CO2 is equivalent to the amount of CO2 fixed during the vegetable life cycle. However, a large portion of the energy that can be generated by the con…
The oxidation of molecules derived from biomass has been used both directly in fuel cells and for the production of clean hydrogen. These processes represent an important alternative for replacing internal combustion engines based on fossil fuels. Despite decades of studies, the interconversion of chemical energy into electrical energy (an object of electrochemistry, and particularly of e…
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…
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…

In the investigation of the origin of living systems, the alkaline hydrothermal vents (AHVs) are proposed as one of the most promising scenario to hatchery life on prebiotic Earth. The so-called AHV theory has proposed an energy-transfer mechanism, based on the chemiosmotic theory, as requisite processes of the first steps of emergence of life. Therefore, submarine environments of AHVs on…
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…
