Co2P2O7‐Ni2P2O7 solid solutions: Structural characterization and color
Wiley (2018-10)NH4[Co1−yNiyPO4]·H2O (0 ≤ y ≤ 1) single crystals were fired to prepare Co2−xNixP2O7 0 ≤ x ≤ 2 solid solutions between 800 and 1200°C. The structure of these solid solutions is α‐M2P2O7 (M = Co, Ni). The contraction of the ... -
Highly porous Ti-Ni anodes for electrochemical oxidations
Universitat Jaume I (2020-09-28)The hydrogen rising economy is demanding an active and durable electrocatalysts based on low-cost, earth abundant materials for water electrolysis. Oxygen electrochemistry plays a key role in renewable energy technologies, ... -
Mechanistic implications of the enantioselective addition of alkylzinc reagents to aldehydes catalyzed by nickel complexes with a-amino amide ligands
The Royal Society of Chemistry (2016-11)The enantioselective alkylation of aldehydes catalysed by nickel(II)-complexes derived from α-amino amides was studied by means of density functional theory (DFT) and ONIOM (B3LYP:UFF) calculations. A mechanism was proposed ... -
Nickel-Cornered Molecular Rectangles as Polycyclic Aromatic Hydrocarbon Receptors
Wiley (2017)Two nickel-cornered organometallic metalla-rectangles containing a pyrene-linked-di-N-heterocyclic carbene have been prepared. The dimensions of one side of the rectangle were modulated by either using pyrazine or ... -
Rhodium, iridium and nickel complexes with a 1,3,5-triphenylbenzene tris-MIC ligand. Study of the electronic properties and catalytic activities
Beilstein-Institut (2015-12-14)The coordination versatility of a 1,3,5-triphenylbenzene-tris-mesoionic carbene ligand is illustrated by the preparation of complexes with three different metals: rhodium, iridium and nickel. The rhodium and iridium complexes ... -
Synthesis and coloring performance of Ni-geikielite (Ni,Mg)TiO3 yellow pigments: Effect of temperature, Ni-doping and synthesis method
Elsevier (2015)Solid solutions of Ni in MgTiO3 ilmenite (geikielite) were investigated as potential yellowish ceramic pigments or dyes. Ni-geikielite samples (Mg1−xNixTiO3, x = 0–0.4) were prepared by solid-state and citrate-gel routes ... -
Synthesis of metal oxide catalysts for water splitting
Universitat Jaume I (2019-10)The hydrogen rising economy is demanding an active and durable electrocatalysts based on low-cost, earth abundant materials for water electrolysis. Oxygen electrochemistry plays a key role in renewable energy technologies, ... -
Synthesis, stability and coloring properties of yellow–orange pigments based on Ni-doped karrooite (Ni,Mg)Ti2O5
Elsevier (2015)Solids solutions of Ni in MgTi2O5 pseudobrookite (karrooite) were investigated to develop new yellowish ceramic pigments or dyes. Ni-Karrooite samples (Mg1−xNixTi2O5) were prepared by ceramic method and through a citrate-gel ...
