In this study, we investigate the effect of KFeO, as a new and soluble Fe salt at alkaline conditions, on oxygen-evolution reaction (OER) of Ni oxide. Both oxidation and reduction peaks for Ni in the presence and absence of Fe are linearly changed by (scan rate). Immediately after the...

Here, we report a strategy to enable catalytic oxygenation with a simple Ni(ii)–bipyridine complex in which electrochemistry is employed to drive the cascade-activation process for the generation of both active Ni(ii)–peroxo species and O2 for the subsequent oxygenation reaction. We anticipate ...
Reaction of the Ni(II)-polyoximate complexes with o-quinones causes the formation of high-valent nickel complexes of the reduced dioxolenes, semiquinones and catecholates.GOLDCAMP, MICHAEL JOSEPH... MJ Goldcamp 被引量: 0发表: 2002年 Characterization of a series of oxygen active complexes conta...
2023 Elsevier Inc.Transition metal oxides have been extensively investigated for oxygen evolution reaction (OER). While the introduction of oxygen vacancies (Vo) was found to be an effective way to enhance the electrical conductivity and the OER electrocatalytic activity of transition metal oxides, ...
Peptides containing histidine at position 2 were observed to undergo spontaneous N-terminal oxidative deamination in aqueous solution in the presence of Ni(II), sulfite, and ambient oxygen. The reaction resulted in the formation of a free carbonyl on the N-terminal alpha-carbon (alpha-ketoamide)...
When heated with bromine vapors or chlorine gas, nickel catches fire forming nickel bromide, NiBr2, and yellow nickel chloride, NiCl2, respectively. Finely divided nickel combines with carbon monoxide to form zero valent nickel tetracarbonyl, Ni(CO)4. The reaction occurs at 50°C and one atmos...
NiO/CNTs (nickel oxide/carbon nanotubes) could be a potential cathode catalyst for oxygen reduction reaction (ORR) in microbial fuel cells (MFCs). It is blended with other high purity oxides and used in a variety of semiconductor applications such as thermistors and varistors. Uses Nickel oxide...
Developing low-cost electrocatalysts to replace precious Ir-based materials is key for oxygen evolution reaction (OER). Here, we report atomically dispersed nickel coordinated with nitrogen and sulfur species in porous carbon nanosheets as an electrocata
surface electronic structure of the platinum–nickel catalyst, and this composite catalyst composed of crystalline platinum–nickel covered by amorphous nickel boride achieves a 27-times enhancement in mass activity relative to commercial platinum/carbon at 0.9 V for the oxygen reduction reaction ...
