In the title complex, [Ni(C(8)H(5)Cl(2)O(3))(2)(H(2)O)(4)], the Ni(II) atom (site symmetry ) adopts a slightly distorted NiO(6) octa-hedral coordination. An intra-molecular O-H⋯O hydrogen bond helps to establish the conformation. In the crystal, further O-H⋯O hydrogen bonds link the mol-ecules.

A NiO-MgO layered, binary thin oxide film has been prepared on a Mo(100) surface and characterized byAuger electron spectroscopy (AES), low energy electron diffraction (LEED) and high-resolution electron energy loss spectroscopy (HREELS or EELS). NiO grows epitaxially on a 20-monolayer (ML) MgO(100) film supported on the Mo(100) surface. At a NiO coverage of <1.8 monolayer, a new surface or int...

With the aim of promoting the Ni/Ce0.8Gd0.2O2-δ (Ni/GDC20) cermet anodic performance of low temperature solid oxide fuel cell (LT-SOFC) [1], nanostructuring platinum nanoparticles on NiO/GDC composite was done by single-step wet-infiltration of hexachloroplatinic acid hexahydrate (H2PtCl6.6H2O) precursor on NiO/GDC20 composite. The anodic polarization resistance was measured using symmetr...

Solid surfaces generally respond sensitively to their environment. Gas phase or liquid phase species may adsorb and react with individual surface atoms altering the solid-gas and solid-liquid electronic and chemical properties of the interface. A comprehensive understanding of chemical and electrochemical interfaces with respect to their responses to external stimuli is still missing. The evolu...

Nanocrystals are promising structures, but they are too large for achieving maximum energy storage performance. We show that rescaling 3-nm particles through lithiation followed by delithiation leads to high-performance energy storage by realizing high capacitance close to the theoretical capacitance available via ion-to-atom redox reactions. Reactive force-field (ReaxFF) molecular dynamics sim...

Transients in the composition of Ni@NiO x core-shell co-catalysts deposited on SrTiO3 are discussed on the basis of state-of-the-art continuous analysis of photocatalytic water splitting, and post-XPS and TEM analyses. The formation of excessive hydrogen (H2:O2 ≫ 2) in the initial stages of illumination demonstrates oxidation of Ni(OH)2 to NiOOH (nickel oxyhydroxide), with the latter catalyzing...

Self-organized TiO 2 nanotubes (TNTs) with average inner diameter of 109 nm, wall thickness of 15 nm, and tube length of 7– 10 μm were loaded with nickel oxide (NiO) nanoparticles via incipient wet impregnation method. The molar concentration of Ni(NO 3 ) 2 ⋅6H 2 O aqueous solution varied in a range of 0.5M–2.5M. The samples were characterized for crystalline phase, morphology, topography, chem...

This project deals with the study of the electronic structure of the NiO nanostructures formed at the early stages of growth of NiO on highly oriented pyrolytic graphite (HOPG). Our main aim is the study of nanostructured NiO systems where possible surface effects are enhanced by the large surface to volume ratio of the nanostructures. In fact, early studies [1] on 3 nm NiO nanoparticles with u...

Herein, NiO-decorated Ni nanowires with diameters ca. 30-150 nm derived from Ni wire backbone (ca. 2 μm in diameter) is directly synthesized on commercially available Ni foam as a renovated anode for Li-ion batteries. Excellent stability with capacity 680 mAh g(-1) at 0.5C (1C = 718 mA g(-1)) is achieved after 1000 cycles. Superior rate capability is exhibited by cycling at extremely high curre...
