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 ... -
Groups IV, V and VI metal oxide-containing hydrotalcite catalysts: state of the art on their catalytic applications
(Elsevier, 2024-07-08)The present contribution is a review paper that summarizes the structure, properties and catalytic applications of hydrotalcite based materials when they are modified by the incorporation of oxide metals from groups 4, 5 ... -
Isotopic study of the influence of oxygen interaction and surface species over different catalysts on the soot removal mechanism
(Elsevier, 2021)In order to improve the catalytic formulations for soot removal in after-treatment emission control technologies for gasoline and diesel engine vehicle, an isotopic study was approached using transitory labeled oxygen ... -
Morphological changes of vanadyl pyrophosphate due to thermal excursions
(Elsevier, 2023-01-01)Vanadyl pyrophosphate (VPP) is the active catalytic phase that converts n-butane to maleic anhydride in fixed beds, fluidized beds, and DuPont’s circulating fluidized bed (CFB). The original CFB concept was based on the ... -
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, ...
