Effect of the modification of the cationic and anionic framework on the structural and electrical properties of lanthanum molybdates
López Vergara, Adrián; Bergillos-Ruíz, Marta; Porras-Vázquez, José Manuel; Marrero-López, David; Losilla, Enrique R. (2019-07-19)
Fluorinated lanthanum molybdates have been prepared at 1500 and 1200 ºC for 1 h and cooled down at 5 ºC min-1. The combination of anionic (F-) and cationic (Nb5+) doping stabilizes the cubic polymorph without needing a ... -

Coordination polymers based in phosphonic acid display a wide range of metalcoordination modes. Moreover, the existence of acidic P-OH groups in their structure, as well as of others functionalized organic group such as ... -
Photocatalytic behavior of phosphonate-based hybrid materials on dyes and phenols degradation
Bazaga-García, Montse; Pérez-Colodrero, Rosario Mercedes; Olivera-Pastor, Pascual; Santacruz-Cruz, María Isabel; García-Aranda, Miguel Ángel (2013-09-25)
There is increasing interest in using heterogeneous catalysis for mineralization of organic pollutants. Within Advanced Oxidation Processes (AOPs), Photo-Fenton reaction is one of the most efficient methodologies. To ... -
Single and solid solutions metal carboxyphosphonates as precursors for phosphorous-containing electrocatalysts
López Vergara, Adrián; El-Refaei, S.M.; Russo, Patricia A.; Vilchez, A; Losilla, Enrique R.; Porras-Vázquez, José Manuel; Olivera-Pastor, Pascual; Pinna, N; Cabeza-Díaz, Aurelio[et al.] (2019-07-19)
Co1-xFex-HPAA metal phosphonates were prepared and pyrolyzed under N2 and H2/Ar flows. The result-ing powders were structural and electrochemically characterised by XRD and CV, respectively. The ob-tained materials possess ... -
