Journal ArticleDOI
Lithium Distribution in Aluminum-Free Cubic Li7La3Zr2O12
TL;DR: In this paper, the authors determined Li sites and occupancies by neutron diffraction of cubic Al-free Li7La3Zr2O12 cubic formwork, with half of tetrahedral sites vacant and long-range ordered.
Journal ArticleDOI
Na-doped ruthenium perovskite electrocatalysts with improved oxygen evolution activity and durability in acidic media
Maria Retuerto,Laura Pascual,Federico Calle-Vallejo,Pilar Ferrer,Diego Gianolio,Amaru González Pereira,Álvaro López García,Jorge Torrero,María Teresa Fernández-Díaz,Peter Bencok,Miguel A. Peña,José Luis García Fierro,Sergio Rojas +12 more
TL;DR: Sodium doping of strontium ruthenate is shown to improve the catalytic durability while maintaining a high O2 evolution activity and illustrates how high OER activity and durability can be simultaneously engineered by chemical doping of perovskites.
Journal ArticleDOI
Metal-insulator transitions, structural and microstructural evolution of rnio3 (r = sm, eu, gd, dy, ho, y) perovskites : evidence for room-temperature charge disproportionation in monoclinic honio3 and ynio3
José Antonio Alonso,María Jesús Martínez-Lope,M. T. Casais,and Miguel A. G. Aranda,María Teresa Fernández-Díaz +4 more
TL;DR: In this article, the authors show that the distortion of the orthorhombic perovskite progressively increases along the series, leading for the smallest Ho3+ and Y3+ cations to a subtle monoclinic distortion (space group P21/n) which implies the splitting of the Ni positions in the crystal.
Journal ArticleDOI
Evolution of the Magnetic Structure of Hexagonal HoMnO3 from Neutron Powder Diffraction Data
A. Munoz,José Antonio Alonso,María Jesús Martínez-Lope,M. T. Casais,José Luis Martínez,María Teresa Fernández-Díaz +5 more
TL;DR: In this paper, a hexagonal, nonperovskite HoMnO3 oxide, containing a triangular arrangement of Mn3+ cations, has been prepared in polycrystalline form by the thermal decomposition of metal citrates.
Journal ArticleDOI
On the Location of Li+ Cations in the Fast Li‐Cation Conductor La0.5Li0.5TiO3 Perovskite
José Antonio Alonso,Jesus Sanz,Jacobo Santamaria,Carlos León,Alejandro Várez,María Teresa Fernández-Díaz +5 more
TL;DR: The unusual coordination and the partially unoccupied sublattice (occupancy factors 1/6 and (1/2) for Li and La, respectively) account for the high mobility of the Li(+) cations.
