Journal ArticleDOI
The Adsorption of Methylene Blue on Eco-Friendly Reduced Graphene Oxide
Fabian Arias Arias,Marco Guevara,Talia Tene,Paola Angamarca,Raul Molina,Andrea Valarezo,Orlando Salguero,Cristian Vacacela Gomez,Cristian Vacacela Gomez,Melvin Arias,Melvin Arias,Lorenzo S. Caputi +11 more
TL;DR: Reduced graphene oxide was prepared by a scalable and eco-friendly method and its potential use for the removal of methylene blue from water systems was explored, and the potential of green-prepared rGO to remove cationic dyes from wastewater systems is shown.
Journal ArticleDOI
Toward Large-Scale Production of Oxidized Graphene.
Talia Tene,Gabriela Tubon Usca,Marco Guevara,Raul Molina,Francesco Veltri,Melvin Arias,Melvin Arias,Lorenzo S. Caputi,Cristian Vacacela Gomez,Cristian Vacacela Gomez +9 more
TL;DR: This eco-friendly method proposes a complete guideline protocol toward large-scale production of oxidized graphene, with potential applications in supercapacitors, fuel cells, composites, batteries, and biosensors.
Journal ArticleDOI
The liquid exfoliation of graphene in polar solvents
Cristian Vacacela Gomez,Marco Guevara,Talia Tene,Luis Villamagua,Gabriela Tubon Usca,Frank Maldonado,Carlos Tapia,Antonino Cataldo,Stefano Bellucci,Lorenzo S. Caputi +9 more
TL;DR: In this paper, a detailed experimental and theoretical investigation seeking to explain the liquid exfoliation of graphene in polar solvents at short sonication time (up to 7h).
Journal ArticleDOI
Preparation of Few-Layer Graphene Dispersions from Hydrothermally Expanded Graphite
Cristian Vacacela Gomez,Talia Tene,Marco Guevara,Gabriela Tubon Usca,Dennys Colcha,Hannibal Brito,Raul Molina,Stefano Bellucci,Adalgisa Tavolaro +8 more
TL;DR: In this article, a novel approach to prepare few-layer graphene dispersions, which is realized by exfoliating natural graphite flakes in a surfactant aqueous solution under hydrothermal treatment and liquid-phase exfoliation, is proposed.
Journal ArticleDOI
Porous Carbon Materials Obtained by the Hydrothermal Carbonization of Orange Juice
Francesco Veltri,Francesca Alessandro,Andrea Scarcello,Amerigo Beneduci,Melvin Arias Polanco,Melvin Arias Polanco,Denia Cid Perez,Denia Cid Perez,Cristian Vacacela Gomez,Cristian Vacacela Gomez,Adalgisa Tavolaro,Girolamo Giordano,Lorenzo S. Caputi +12 more
TL;DR: Porous microspheres with some degree of graphitization and high nitrogen content, a specific surface of 1725 m2/g, and a pore size distribution that make them good candidates for supercapacitor electrodes are found.
