A comparison between oxidation of activated carbon by electrochemical and chemical treatments

Berenguer, Raúl; Marco-Lozar, Juan Pablo; Quijada Tomás, Cesar; Cazorla-Amoros, Diego; Morallón, Emilia (Elsevier, 2012)

The anodic oxidation of a granular activated carbon (GAC) in NaCl solution has been studied. The influence of the electrocatalyst-anode material, applied current and time of treatment on both the surface chemistry and ...
Copper-doped cobalt spinel electrocatalysts supported on activated carbon for hydrogen evolution reaction

Flores-Lasluisa, Jhony X.; Quilez-Bermejo, Javier; Ramirez-Perez, Ana C.; Huerta, Francisco; Cazorla-Amorós, Diego; Morallón, Emilia (MDPI AG, 2019)

[EN] The development of electrocatalysts based on the doping of copper over cobalt spinel supported on a microporous activated carbon has been studied. Both copper-cobalt and cobalt spinel nanoparticles were synthesized ...
Double-template fabrication of three-dimensional porous nickel electrodes for hydrogen evolution reaction

Herraiz-Cardona, Isaac; Ortega Navarro, Emma María; Vázquez-Gómez, Lourdes; Pérez-Herranz, Valentín (PERGAMON-ELSEVIER SCIENCE LTD, 2012-02)

[EN] Three-dimensional (3D) porous nickel structures were fabricated via a double-template electrochemical deposition process. The construction of the foam structures was achieved by means of a hydrogen bubble dynamic ...
Electrocatalytic Oxidation of Cyanide on Copper-doped Cobalt Oxide Electrodes

Berenguer, R.; La Rosa-Toro, A.; Quijada, C.; Morallon, E. (Elsevier, 2017)

[EN] Copper and copper oxides are well-known excellent catalysts in several chemical processes, but their low mechanical and electrochemical stability restrict their direct utilization as electrodes in electrolytic processes. ...
High-current water electrolysis performance of metal phosphides grafted on porous 3D N-doped graphene prepared without using phosphine

Hu, Hu Jiajun; Peng, Lu; Primo Arnau, Ana Maria; Albero-Sancho, Josep; García Gómez, Hermenegildo (Elsevier, 2022-05-18)

[EN] Development of efficient and stable electrodes for hydrogen and oxygen evolution from water constituted of abundant elements and prepared by sustainable and scalable procedures is of considerable importance for producing ...
Solvent-Free Synthesis of ZIFs: A Route toward the Elusive Fe(II) Analogue of ZIF-8

Lopez-Cabrelles, J.; Romero, J.; ABELLÁN SÁEZ, GONZALO; Gimenez-Marques, M.; Palomino Roca, Miguel; Valencia Valencia, Susana; Rey Garcia, Fernando; Minguez Espallargas, G. (American Chemical Society, 2019-05-01)

[EN] Herein we report the synthesis of an elusive metal-organic framework, the iron(II) analogue of ZIF-8 with the formula Fe(2-methylimidazolate)(2), here denoted as MUV-3. The preparation of this highly interesting porous ...
