| Popis: | 2 Figuras.-- Presentado en el congreso "Carbon 2019", celebrado en Lexington, KY, EE.UU., 14-19 julio. The limited fossil fuels reserves and the increasing global warming make necessary a transition to sustainable energy production and environment-friendly technologies. However, renewable sources of energy have an intermittent nature, so the improvement of energy storage devices together with a better energy management are needed. Supercapacitors (SC) are already in use in many car models for brake energy regeneration, in Start-Stop systems (not only in electric vehicles) and in hybrid systems along with batteries. Activated mesoporous carbons are valuable materials to be used as electrodes for SCs due to their high surface area and hierarchical pore structure that facilitates the diffusion of electroactive species. Herein, an easy and green one-pot synthesis method was developed to produce mesoporous carbons through ball milling of mimosa tannin as carbon precursor, with Pluronic© F127 and water. CO2 activation carried out on selected ordered and disordered mesoporous carbons (OMCs and DMCs, respectively) allowed improving their textural properties. Activated OMCs and DMCs were tested as electrodes for SCs.
