Activated carbon monoliths from lignocellulosic biomass waste for electrochemical applications.
(Elsevier, 2019-03-05)The valorization of lignocellulosic biomass waste into bio-based materials is proposed in this work in order to obtain low-cost materials and to reduce environmental impacts. Cylindrical activated carbon monoliths (ACMs) ... -
Activation of electrospun lignin-based carbon fibers and their performance as self-standing supercapacitor electrodes
(2020-02-17)The production and activation of self-standing carbon electrodes from electrospun lignin fibers was analyzed in this work. Carbon microfibers were prepared at 900 °C from air-stabilized spun cloths by direct carbonization ... -
Biomass-derived binderless fibrous carbon electrodes for ultrafast energy storage.
(Royal Society of Chemistry, 2015-10-14)The possibility of storing energy efficiently and sustainably at little cost is crucial to prevent climate change and the exhaustion of natural resources. In this work we demonstrate that interconnected and porous carbon ... -
Evaluation of acetanilide and antipyrine adsorption on lignin-derived activated carbons.
(Elsevier, 2024-07-01)In this study, the removal of two emerging pollutants (EPs), antipyrine and acetanilide, through adsorption on activated carbons (ACs) prepared by chemical activation of Organosolv lignin with H3PO4 were evaluated. ACs with ... -
Lignin-derived Pt supported carbon (submicron)fiber electrocatalysts for alcohol electro-osidation.
(Elsevier, 2017-04-03)Lignin fibers, with and without phosphorus, and loaded with platinum have been prepared in a single step by electrospinning of lignin/ethanol/phosphoric acid/platinum acetylacetonate precursor solutions. Thermochemical ... -
Oxidative electrochemical depolymerization of lignin using highly active self-standing electrocatalysts prepared by electrospinning of lignin
(Elsevier, 2025-02)Electrooxidative depolymerization of lignin enables obtaining renewable value-added chemicals under soft operation conditions. However, current nickel foam electrodes do not fully utilize their active phase. In this study, ... -
Preparation of different carbon materials by thermochemical conversion of lignin.
(Frontiers, 2014-12-04)Lignin valorization plays a crucial role within the modern biorefinery scheme from both the economic and environmental points of view; and the structure and composition of lignin makes it an ideal precursor for the preparation ...
