Advancements in electrochemical technologies for energy production and storage have been driven by the detailed design of catalysts, supported by a comprehensive experimental and theoretical understanding of surface reactions. These include the oxygen reduction and evolution reactions (ORR and OER), which are critical processes in energy conversion systems. This research has identified promising alternatives to the use of unsustainable noble metals in these reactions, contributing to the development of more sustainable and efficient energy technologies.
A significant focus has been placed on biomass-derived carbons, which were modified by introducing heteroatoms such as oxygen and phosphorus, and by incorporating carbon nanotubes (CNTs) during the synthesis and activation process. These modifications enhance the performance of carbon-based catalysts, making them viable options for various electrochemical applications. The potential of CNT materials as electrodes in flexible energy storage devices has been thoroughly explored, highlighting their exceptional conductivity, flexibility, and mechanical strength.
Additionally, cork-based electrodes are being investigated for the development of innovative and eco-friendly supercapacitors, which aim to support the ongoing transition to sustainable energy systems. These electrodes are particularly attractive due to their natural origin, low environmental impact, and potential to deliver high-performance energy storage solutions. This research represents a critical step toward the realization of greener, more efficient energy production and storage technologies.
