Metal carboxyphosphonates-based 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.] (2019-10-01)
Co1-xFex-HPAA metal phosphonates were prepared and pyrolyzed under N2 and H2/Ar flows. The resulting powders were structural and electrochemically characterized by XRD and CV, respectively. The obtained materials possess ... -
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 ... -
Tuning the activity of cobalt 2-hydroxyphosphonoacetates-derived electrocatalysts for water splitting and oxygen reduction: insights into the local order by pair distribution function analysis
Vílchez-Cózar, Álvaro; Pérez-Colodrero, Rosario Mercedes; Bazaga-García, Montse; Marrero-López, David; El-Refaei, S.M.; Russo, Patricia A.; Pinna, Nicola; Olivera-Pastor, Pascual[et al.] (Elsevier, 2023)
Pyrophosphate- or phosphide-based iron/cobalt electrocatalysts were prepared from the metal (R,S)−2-hydroxyphosphonoacetates to evaluate the effects of metal composition, N-doping and P-enrichment on the electrocatalytic ...
