Comportamiento electroquímico de carbones activados con presencia de grupos superficiales de fósforo
Gallardo-Fuentes, Aurora; Ruiz-Rosas, Ramiro Rafael
; Berenguer-Betrian, Raul; Morallón, Emilia; Cazorla-Amorós, Diego; Nishihara, Hirotomo; Kyotani, Takashi; Rodriguez-Mirasol, Jose; Cordero-Alcántara, Tomás[et al.] (2013-11-05)
Debido a su elevada superficie específica y una combinación única de conductividad, estabilidad y gran versatilidad química-estructural, los carbones activados (CAs) se emplean como electrodos en diversas aplicaciones ... -
Efecto del H3PO4 en la preparación de fibras de carbono a partir de lignina. Mejoras en el proceso de estabilización y propiedades finales
Garcia-Mateos, Francisco Jose; Berenguer-Betrian, Raul; Rodriguez-Mirasol, Jose; Cordero-Alcántara, Tomás (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
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 ... -
Electrochemical behavior of pt- a d pd-supported activated carbons with different functionalities
Gallardo-Fuentes, Aurora; Berenguer-Betrian, Raul; Nishihara, Hirotomo; Kyotani, Takashi; Rodriguez-Mirasol, Jose; Cordero-Alcántara, Tomás[et al.] (2014-07-28)
Due to their relatively low price, high surface area and versatile physic-chemical properties, conductive carbon materials are considered among the most promising supports of electroactive species and/or catalysts for ... -
In situ characterization of porous VPO catalysts with fibrous structure: Identifying the redox behavior and the stability of active sites
Berenguer-Betrian, Raul; Fornells, Jaime; Rodriguez-Mirasol, Jose; Cordero-Alcántara, Tomás; Ford, Michael; Wachs, Israel E.[et al.] (2016-09-09)
Two VPO materials with fibrillar morphology have been prepared by the aid of electrospinning technique. One is a VPO carbon-supported material (VCF200) with fibrous morphology and very high surface area that is stable under ... -
Novel lignin-based fibrous carbon materials
Berenguer-Betrian, Raul; Garcia-Mateos, Francisco Jose; Rodriguez-Mirasol, Jose; Cordero-Alcántara, Tomás (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 ... -
