[ES] La presente Tesis Doctoral se centra en el desarrollo de nanoestructuras de óxido de zinc (ZnO) mediante anodizado electroquímico en diferentes condiciones para su aplicación en el área energética, en particular, en ...
Electrochemical formation of novel TiO2-ZnO hybrid nanostructures for photoelectrochemical water splitting applications

Sánchez Tovar, Rita; Blasco-Tamarit, E.; Fernández Domene, Ramón Manuel; Villanueva-Pascual, M.; Garcia-Anton, Jose (Elsevier, 2020-04-25)

[EN] In this study, hybrid ZnO-TiO2 nanostructures have been synthesised by means of a simple electrochemical anodisation of titanium and subsequently ZnO electrodeposition. The influence of Zn(NO3)(2) concentration and ...
Electrochromic switching of electrodeposited ZnO+Zn5(OH) 8Cl2 films

Rayón Encinas, Emilio; Cembrero Cil, Jesús; Marí Soucase, Bernabé (Elsevier, 2011)

This study reports the effect of optical switching of electrodeposited ZnO + Zn5(OH)8Cl2 films on a gold electrode in a bath of 0.05 M Zn(NO3)2 + 0.1 M KCl. The coating turns black when cathodic polarization is applied yet ...
Formation of ZnO nanowires by anodization under hydrodynamic conditions for photoelectrochemical water splitting

Batista-Grau, Patricia; Sánchez Tovar, Rita; Fernández Domene, Ramón Manuel; Garcia-Anton, Jose (Elsevier, 2020-01-15)

[EN] The present work studies the influence of hydrodynamic conditions (from 0 to 5000 rpm) during Zn anodization process on the morphology, structure and photoelectrocatalytic behavior of ZnO nanostructures. For this ...
High-Efficiency Electrodeposition of Large Scale ZnO Nanorod Arrays for Thin Transparent Electrodes

Pullini, D.; Pruna, Alina Iuliana; Zanin, Stefano; Busquets Mataix, David Jerónimo (Electrochemical Society, 2012)

In the present work an effective technique to synthesize large-scale c-axis oriented ZnO nanorod (NR) arrays is presented. The manuscript reports a single-step cathodic electrodeposition, either in aqueous and organic ...
Influence of Deposition Potential on Structure of ZnO Nanowires Synthesized in Track-Etched Membranes

Pruna, Alina Iuliana; Pullini, Daniele; Busquets Mataix, David Jerónimo (Electrochemical Society, 2012)

Single-crystal ZnO nanowires long up to several microns were fabricated by one-step electrochemical deposition. A template-based process employing track-etched polycarbonate (TE-PC) membranes was used for this purpose. The ...
Influence of Zn(NO3)2 concentration during the ZnO electrodeposition on TiO2 nanosponges used in photoelectrochemical applications

Navarro-Gázquez, P.J.; Blasco-Tamarit, E.; Muñoz-Portero, María-José; Solsona, B.; Fernández-Domene, M.; Sánchez Tovar, R.; Garcia-Anton, Jose (Elsevier, 2022-05-15)

[EN] TiO2/ZnO hybrid nanostructures were formed by electrochemical anodization of titanium and subsequently ZnO electrodeposition. Different Zn(NO3)(2) concentrations were used for electrodeposition (10-60 mM). A structural, ...
Nanostructured hybrid ZnO thin films for energy conversion

Moya Forero, Mónica Mercedes; ANURA SAMANTILLEKE; Mollar García, Miguel Alfonso; Marí Soucase, Bernabé (SpringerOpen, 2011)

We report on hybrid films based on ZnO/organic dye prepared by electrodeposition using tetrasulfonated copper phthalocyanines (TS-CuPc) and Eosin-Y (EoY). Both the morphology and porosity of hybrid ZnO films are highly ...
