Enhanced Visible Light-Driven Photocatalytic Water-Splitting Reaction of Titanate Nanotubes Sensitised with Ru(II) Bipyridyl Complex

Malizia, Mauro; Scott, Stuart A.; Torrente-Murciano, Laura; Garcia-Baldovi, Hermenegildo; Boies, Adam M.; Aljohani, Talal A. (MDPI AG, 2023-11)

[EN] The ion exchange of Na+ cations was used to photosensitise titanates nanotubes (Ti-NTs) with tris(2,2'-bipyridine)ruthenium(II) cations (Ru(bpy)(3)(2+)); this yielded a light-sensitised Ti-NTs composite denoted as ...
Estudio de la recuperación de nitrógeno del permeado de un AnMBR mediante la combinación de zeolitas y contactor de membranas de fibra hueca.

Izquierdo Rúa, Wilmer Andrés (Universitat Politècnica de València, 2024-07-30)

[ES] Dentro de los contaminantes más habituales de las aguas residuales se encuentran los nutrientes, como el nitrógeno. El vertido de altas concentraciones de este elemento en zonas sensibles puede generar problemas ...
Evaluation of two ion-exchange membranes for the transport of tin in the presence of hydrochloric acid

García Gabaldón, Montserrat; Pérez-Herranz, Valentín; Ortega Navarro, Emma María (Elsevier, 2011-01-19)

The transport properties of two ion-exchange membranes in the presence of tin, as Sn(II) and Sn(IV), were investigated by chronopotentiometry and current-voltage curves. Since tin forms positively or negatively charged ...
Incorporation of photoactive TiO2 in an aluminosilicate inorganic polymer by ion exchange

Gasca-Tirado, José Ramón; Manzano Ramirez, Alejandro; Villaseñor-Mora, Carlos; Muñiz-Villarreal, M. S.; Zaldivar-Cadena, A. A.; Rubio-Ávalos, José Carlos; Amigó Borrás, Vicente; Nava Mendoza, Rufino (Elsevier, 2012-05-01)

In the present paper, it is described a procedure to ion exchange in an aluminosilicate inorganic polymer (geopolymer) in order to incorporate photoactive TiO 2. Metakaolin base geopolymers synthesized at 40 and 90 °C were ...
