A general protocol for the selective hydrogenation and deuteration of a variety alkenes is presented. Key to success these reactions use specific nickel-graphitic shell-based core–shell-structured catalyst, which conveniently prepared by impregnation subsequent calcination nickel nitrate on carbon at 450 °C under argon. Applying this nanostructured both terminal internal alkenes, are industrial...
Reaction of cobalt(II) nitrate with potassium seleno-cyanate and pyridazine leads to single crystals of the title compound, [Co(NCSe)(2)(C(4)H(4)N(2))(4)]·2C(4)H(4)N(2), which is isotypic with its nickel(II) thio-cyanate analogue. The Co(2+) cations are coordinated by two N-bonded seleno-cyanate ligands and four N atoms from four pyridazine ligands into discrete complexes. The complexes are arr...
The title complex, [Ni(2)(C(4)H(8)N(4)O(2))(6)](NO(3))(4)·2CH(4)O, contains a centrosymmetric binuclear nickel(II) complex bridged by a pair of 4-amino-3,5-bis-(hydroxy-meth-yl)-1,2,4-triazole ligands. The separation between the Ni(II) atoms is 3.962 (1) Å. The Ni atoms are in a slightly distorted octa-hedral coordination. Inter-molecular N-H⋯O, N-H⋯N and O-H⋯O hydrogen bonds connect the ligand...
Mixed ligands biologically active complexes of cobalt(II), copper(II) and nickel(II) with nicotinoylhydrazine-derived ONO, NNO and SNO donor schiff-base ligands having the same metal ion but different anions such as sulphate, nitrate, oxalate and acetate have been synthesised and characterised on the basis of their physical, analytical and spectral data. In order to evaluate the role of anions ...
A catalytic technique to enhance graphite formation in nongraphitizing carbons was adapted to work with three-dimensional wood-derived scaffolds. Unlike many synthetic graphite precursors, wood and other cellulosic carbons remain largely disordered after high temperature pyrolysis. Using a nickel nitrate liquid catalyst and controlled pyrolysis conditions, wood-derived scaffolds were produced s...
The application of a magnetic field unexpectedly alters the rest potential of ferromagnetic electrodes in paramagnetic solutions of their salts. Anodic shifts of up to 60 mV in a field of 1 tesla were observed for 1 M iron electrodes in iron nitrate solution. The magnitude of the shift depends on magnetic field strength and orientation and it varies with the anion used. The shift is smaller for...
A tetranuclear mixed ligand copper(II) complex of a pyrazole containing Schiff base and a hydroxyhexahydropyrimidylpyrazole and copper(II) and nickel(II) complexes of the Schiff base having N-donor atoms have been investigated. A 2 equiv amount of 5-methyl-3-formylpyrazole (MPA) and 2 equiv of 1,3-diamino-2-propanol (1,3-DAP) on reaction with 1 equiv of copper(II) nitrate produce an unusual tet...
This paper reveals the results of metallic-based nanoparticle's effect on performance, emission, and vibration a diesel engine. Various metal-based nanoparticles such as Nickel (II) nitrate hexahydrate (Ni(NO3)2.6H2O), Silver (AgNO3), Manganese hydrate (Mn(NO3)2.xH2O) were chosen fuel additives into dosage with 25 50 ppm. In experimental tests, to identify combined silver manganese nickel, was ...
Ni-doped carbon aerogel catalysts were prepared through sol-gel polycondensation of furfural with resorcinol in the presence of nickel nitrate salts, followed by drying at ambient pressure and then carbonization in N2. The catalysts were used for catalytic transfer hydrogenation of aromatic nitro compounds with propan-2-ol as hydrogen donor and KOH as promoter, and have been found to exhibit ex...
Cobalt substituted lithium–nickel oxides were synthesized by a solid-state reaction procedure using lithium nitrate, nickel hydroxide and cobalt oxalate precursor and were characterized as cathodes for molten carbonate fuel cell (MCFC). LiNi0.8Co0.2O2 cathodes were prepared using non-aqueous tape casting technique followed by sintering in air. The X-ray diffraction (XRD) analysis of sintered Li...
