To meet the growing global energy demand, clean and low-cost solutions have been increasingly sought, especially due to climate change and the global commitment to reduce carbon emissions. Among the various renewable technologies, solar energy presents itself as a strong candidate with the potential to meet current and future demands. A limitation in solar energy is its non-continuous sou…
According to the International Energy Agency (IEA), 80% of the global energy demand is derived from fossil fuels which are non-renewable energy sources and their use implicate in environmental consequences contribuiting to pollution and climate change effect. To address these problems, much effort has been made towards a clean energy development and some reactions are at the core of the e…
Positive electrode materials for rechargeable batteries are the focus of intense research and subject to a wide range of challenges for its uses in energy storage. The development of Li-ion batteries is restricted by electrochemical and thermodynamic limits; furthermore, the scarcity and high cost of Li-based minerals increase the production cost, alongside safety concerns and the need of…
This project encompasses the development of facile, versatile, and environmentally friendly methodologies to enable the study of a wealth of new nanomaterials (inorganic, organic and/or hybrids thereof) having controlled and well-defined size, shape, composition, structure (solid or empty interiors) and architectures. They will be immobilized and functionalized using various techniques ai…

The high global energy consumption, mainly caused by the numerous portable devices, and the need to diversify the global energy supply have promoted the search for better energy storage technologies. In this context, new electrochemical storage devices stand out, especially lithium-sulfur batteries (LiBSs). This is because sulfur has a high theoretical energy capacity (1675 mA h g-1), hig…
In accordance with the world's tendency the search for more sustainable energy matrices in order to replace non-renewable energy sources, there is a global need for the development of eco-friendly technologies. These actions aim to sustain the current lifestyle, regarding energy and food consumption and reduce the environmental impact of human activities. Therefore, the development and im…
The utilization of fossil fuels increased the greenhouse effect around the planet because of the emission of GreenHouse Gases (GHG). Between them, the most studied is the carbon dioxide, due its uncontrolled growth at the atmosphere. To solve this problem, technologies are being develop along the last years to produce renewable fuels and clean energies, that do not depend on the burn of t…

With nanotechnology, new electrode materials have softened the boundaries between electrochemical double-layer capacitors (EDLCs) and batteries based on Na+ or Li+ ion intercalation. Thus, a pseudocapacitive device and a battery can share the same type of negative electrode in different asymmetric configurations, i.e., the same negative electrode combined with a positive high surface area…
Electrochemical systems for energy storage have had a fundamental role for mobile technology as well as for making renewable energy sources viable. However, with the increasing energy demand, the scientific community works on improving the consolidated technology, based on Li-ion intercalation, and on developing new technologies, such as Na-ion batteries. One possible approach is the use …
Methanol is a platform molecule at the petrochemical industry, used in the synthesis of several chemical feedstocks, besides its central role in several large-scale industrial processes, e.g. biodiesel synthesis by transesterification process. Currently, at the industry, methanol is produced mostly from syngas (CO + H2) at high temperatures and pressure, an expensive and energy-intensive …

Electrochemical energy storage (EES) is becoming more prevalent in the power grid, enabling the concentration of electricity generation on intermittent renewable sources. Positive conversion electrodes for the next generation of lithium-sulfur (Li-S) batteries have attracted considerable interest. This is because Li-S systems have high specific capacity and energy. However, the Li-S syste…
The improvement of energy storage devices is always in development, together with the use of electrochemical capacitors. It is important to obtain materials which present high surface area to increase the electrode capacitance and in consequence, the energy of the device. Thus, the use of thermally reduced and hydrothermally reduced graphene oxide ensures this requirement. Using Ionic Liq…
In this project we carried out a novel methodology of synthesis of platinum-based nanoparticles with controlled morphology. The preparation involves successive steps of leaching and re-deposition of a supported "starting material", transforming the shape of the naturally-formed platinum nanoparticles into preferentially nanocubes. Halide ions are used to leach and control the shape of the…
