Co-modification of Ni-based type Raney electrodeposits for hydrogen evolution reaction in alkaline media

Herraiz Cardona, Isaac; González Buch, Cristina; Valero Vidal, Carlos; Ortega Navarro, Emma María; Pérez-Herranz, Valentín (Elsevier, 2013)

[EN] In this work, high performance Ni and Ni-Co porous electrodes are prepared using the Raney strategy by galvanic co-deposition for hydrogen evolution reaction (HER) in alkaline solution (KOH 30 wt.%). The incorporation ...
Desarrollo de nuevos materiales de cátodo para la reacción de evolución de hidrógeno (HER)

González Buch, Cristina (Universitat Politècnica de València, 2014-11-18)

[EN] The high electrode overpotentials for HER hinder the high scale hydrogen production by means of alkaline water electrolysis. In order to obtain cathodes with lower overpotentials, macroporous Ni-Co electrodeposits ...
Desarrollo y caracterización de nuevos materiales de cátodo basados en aleaciones de níquel para la reacción de evolución de hidrógeno en medio alcalino

González Buch, Cristina (Universitat Politècnica de València, 2016-09-01)

[EN] The current energy system, based basically on the use of fossil fuels is a non-sustainable system and the research for new energy alternatives is necessary. Hydrogen is an ideal energy carrier to become the future ...
Development of Ni-Mo, Ni-W and Ni-Co Macroporous Materials for Hydrogen Evolution Reaction

González Buch, Cristina; Herraiz Cardona, Isaac; Ortega Navarro, Emma María; Garcia-Anton, Jose; Pérez-Herranz, Valentín (Associazione Italiana Di Ingegneria Chimica, 2013)

[EN] The hydrogen evolution reaction (HER) is the cathodic process in many important electrochemical technologies. According to the Brewer intermetallyc bonding theory, molybdenum and tungsten were alloyed with nickel ...
Energy Efficiency Improvement of Alkaline Water Electrolysis by using 3D Ni Cathodes Fabricated via a Double-Template Electrochemical Process

Herraiz Cardona, Isaac; González Buch, Cristina; Ortega Navarro, Emma María; Garcia-Anton, Jose; Pérez-Herranz, Valentín (Associazione Italiana Di Ingegneria Chimica, 2013)

[EN] Alkaline water electrolysis is one of the easiest methods for hydrogen production, offering the advantage of simplicity. Moreover, it represents an environmentally friendly technology for production of high ...
Modification of porous nickel electrodes with silver nanoparticles for hydrogen production

Pérez-Herranz, Valentín; Medina, R.; Taymans, P.; González-Buch, C.; Ortega Navarro, Emma María; Sánchez-Loredo, G.; Labrada-Delgado, G.J. (Elsevier, 2018-01)

[EN] Silver nanoparticles were electrodeposited into the surface of a macroporous Ni electrode. The developed electrodes were characterized morphologically by confocal laser scanning microscopy and field emission scanning ...
