Assessment of the roughness factor effect and the intrinsic catalytic activity for hydrogen evolution reaction on Ni-based electrodeposits

Herraiz Cardona, Isaac; Ortega Navarro, Emma María; Garcia-Anton, Jose; Pérez-Herranz, Valentín (Elsevier, 2011-08)

The hydrogen evolution reaction (HER) was studied in 30 wt.% KOH solution at temperatures ranging between 30 and 80 °C on three type of electrodes: (i) rough pure Ni electrodeposits, obtained by applying a large current ...
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 ...
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 ...
Study of the catalytic activity of 3D macroporous Ni and NiMo cathodes for hydrogen production by alkaline water electrolysis

González Buch, Cristina; Herraiz Cardona, Isaac; Ortega Navarro, Emma María; García Antón, José; Pérez Herranz, Valentín (Springer Verlag (Germany), 2016-07)

Platinum is the electrode material with the highest catalytic activity for the hydrogen evolution reaction (HER). However, its high cost and scarcity are the two major barriers for its usage in the industrial alkaline ...
