Ammonia (NH3) production is a process of high scientific, technological and commercial interest due to its wide range of applications, such as in fertilizers and fuel. he industrial process, known as Haber-Bosch, consists of the reaction of N2 and H2 gases under high temperature (~500°C) and pressure (200-300 atm) conditions and, due to the high energy demand of the process, it consumes 1…
The electrocatalytic synthesis of ammonia from the reduction of nitrate ions has emerged as a promising technology to replace the energy-intensive Haber-Bosch process. Ammonia can be synthetized electrochemically with interesting efficiencies and formation rate values, and when coupled with a sustainable energy matrix, a "green" seal can be obtained. Among several metals, Cu has shown the…
This project proposes a bio-inspired synthesis route of dissipative materials, created in conditions away from the thermodynamic equilibrium, as paradigmatic catalysts for the production of dense energy carriers from the electrochemical reduction of carbon dioxide. The materials will be synthesized at the solid/liquid interface by nonlinear electrodeposition reactions, aiming at a higher …

We propose in this project a systematic study of the electrochemical synthesis of self-organized nanostructured metallic multilayers based on controlling methodologies in nonlinear chemical dynamics. This contribution can rationalize the kinetic mechanisms responsible for the spontaneous formation of chemical architectures in micro and nanoscale in addition to the creation of novel materi…
Electrochemical oscillators are considered unique model-systems in mimicry emergent behavior ubiquitously found in nature. This complexity, expressed in terms of spontaneous formation of self-organized patterns far from thermodynamic equilibrium, can be manipulated accurately by techniques developed in synchronization engineering. In practice, the application of controlling methodologies …
The impact of lithium-ion batteries on the present-day energetic matrix is evident. Yet, optimization in the making of these devices is still desired, and a deep and clear understanding of these batteries' intercalation mechanism would be helpful for this search. In 2018, the first potential oscillations during the charge and discharge of a lithium-ion battery was reported, obtained in a …
Ammonia is a dense energy carrier and has been studied as an alternative to fossil fuels. The ammonia production by the Haber-Bosch process was one of the main technogical developments of the 20th. century, allowing its production on large scale. However, this process led to a disturbance in the nitrogen cycle, in addition to relying on fossil fuels for the N2 hydrogenation and demanding …
New technologies that mimic photosynthesis, a complex reaction that occurs in living organisms, are vital in today's society since they bring the possibility of converting carbon dioxide into energy-rich molecules such as methane and ethylene. The development of new methodologies for control and rational design of materials that can be used as catalysts must be carried out keeping in mind…
This work aims to study the effect of the adsorption of azobenzene molecules on metallic surfaces, preferably on platinum and polycrystalline copper, and from this knowledge, to control the growth of self-organized nanostructures during the oscillatory electrodeposition of Cu/Cu2O by the geometric isomerization of these molecules. The control will be done through the irradiation of light …
The production of nanostructured materials in oscillatory regimes far from thermodynamic equilibrium have been presented as an alternative synthesis methodology in which unprecedented physic-chemical proprieties can be achieved. Specifically in the oscillatory electrodeposition of metallic Cu/Sn multilayers, major fundamental interest (understanding the formation mechanism) and technologi…
This work involves the theoretical study of the oscillatory dynamics present during the dissolution of nickel in acid medium and will be solved through the approximation numerical integration method called the fourth-order Runge-Kutta. With the solution of the equations, time series will be analyzed by plotting one of the variables by time, specifically the potential of the double electri…

Recent reports have shown that phase separating electrodes may induce macroscopic voltage oscillations in Li-ion batteries. These oscillations happen as many electrode particles phase transition in conjunction, and how they synchronize is still poorly understood. The individual particle intercalation depends on the surface condition of every other particle, as they are coupled by their in…
CO2 reduction reaction (CO2RR) is considered as one of the most appealing approaches to convert this greenhouse gas into feedstock and fuels. The formation of formic acid/formate has been highlighted as the most economically feasible product obtained from CO2. This is mainly due to the possibility of employing abundant and relatively inexpensive catalysts, such as Sn and Bi. The electroly…
The nitrogen cycle was globally perturbed by the excessive use of fertilizers for food production. One of the most harmful symptoms of such disturbance is the accumulation of reactive nitrogen into the environment, especially nitrate, the nitrogen derivative most oxidized species, being a serious pollutant in groundwater, rivers, and lakes. The electrochemical nitrate reduction is a susta…
