Materials in their various natures and scales are undoubtedly protagonists to facing the challenges of today's society, incluing those related to global warming and greenhouse gas emissions, to the growing energy demand and medicine. Nanocatalysts, biocatalysts and hybrids, energy storage and conversion devices are among the materials that may ensure new advances in a sustainable way. Th…
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…
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…
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 investigates the incorporation of MOFs and COFs as pore-forming agents in hard carbon nanofibers for self-supporting negative electrodes in sodium-ion batteries (SIBs). These materials, with highly porous structures that can be chemically modified to include heteroatoms such as nitrogen and sulfur, enhance the ion adsorption capacity and electrical conductivity of hard carbon…
Secondary batteries play a central role in today's society, driven by the growing demand for renewable energy storage devices. In this context, sodium-ion batteries (SIBs) have emerged as potential solutions for large-scale, low-cost stationary energy storage compared to lithium-ion batteries (LIBs). However, many SIB challenges remain to be overcome, such as increasing coulombic efficien…

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…
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…

This project aims to complement ongoing research exploring the use of self-supporting hard carbon nanofiber (HCNF) electrodes as negative electrodes in sodium-ion batteries (SIBs). Although these electrodes demonstrate high capacity in mAh g¿¹ and notable chemical and mechanical stability, it remains necessary to enhance the initial coulombic efficiency (ICE) to meet practical application…
This project will investigate the impact of water on catalyst surfaces in ionic liquids (ILs) using in-situ infra-red spectroscopy. Over recent decades, anthropogenic rising in CO2 levels in Earth's atmosphere, now at approximately 420 ppm, have stimulated interest in electrocatalysis as a method for CO2 transformation under ambient conditions. Aqueous electrolytes, however, have limited …
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…
