Alcohol decomposition on basic/acid lignin-derived submicron diameter carbon fibers
(2018-07-12)The use of lignin, the second most abundant polymer in nature, along with a simple and versatile technique, electrospinning, represents an advantageous and promising approach for the preparation of carbon fibers. In ... -
Efecto del H3PO4 en la preparación de fibras de carbono a partir de lignina. Mejoras en el proceso de estabilización y propiedades finales
(2015-11-06)El presente trabajo propone un nuevo método de preparación de fibras de carbono mediante electrohilado de mezclas de lignina/H3PO4, en el que se obtienen resultados que aceleran el proceso de preparación de estos materiales ... -
Effect of phosphorous groups on the stabilization and activation of low-cost lignin fibers prepared by electrospinning
(2013-11-25)The feasible wider use of carbon fibers in many of their current and potential applications demands a reduction of their manufacturing costs. In this sense, the use of lignin as an abundant, renewable and low-cost carbonaceous ... -
Electrospinning of alcell lignin for the preparation of ORR electrocatalysts
(2019-10-28)Carbon fibers are one of the components of the electrode assemblies used in fuel cells. They are usually prepared from polyacrylonitrile, a non-renewable synthetic polymer. Lignin is a highly abundant biopolymer that is ... -
Electrospun iron-containing sustainable carbon submicron fibers as Fischer-Tropsch catalyst
(2023)The problems derived from fossil fuels usage such as climate change and energy crises have led to seek for alternatives. Biomass is a renewable source which can be used to produce fuels and olefins via Fischer-Tropsch from ... -
Fischer-Tropsch synthesis over lignin-derived cobalt-containing carbon fiber catalysts prepared in a single step by electrospinning
(2022)In the present, work submicron-sized cobalt-containing lignin fibers have been prepared by the electrospinning technique, using Alcell lignin as carbon precursor, a low-cost co-product of the paper making industry. ... -
Highly conductive microporous carbon fibers by electrospinning of lignin/phosphoric acid/ethanol solutions
(2019-11-06)This contribution reports the preparation of electrospun lignin-based carbon fibers at different carbonization temperatures and the influence of heat treatments at temperatures ranging from 900 to 1600 ºC. The influence ... -
Novel lignin-based fibrous carbon materials
(2014-07-28)Lignin is (and will be) an important co-product in many lignocellulosic biomass-derived industries, such as pulp and paper mills (and the future biorefineries, when the concept of bio-economy be developed). The development ...
