Hydrothermally synthesized electrodes of Co3O4@MnO2@NiO/GO were produced for use in supercapacitors. Graphene oxide (GO) was incorporated into the nanocomposites used electrode synthesis due to its great surface area and electrical conductivity. The synergistic alliance among these composites GO enhances performance, life span, stability. structural properties obtained from X-ray diffraction (X...
Reaction of Fe3(CO)12 with 1,2-dithiolene HSC6H2Cl2SH affords a mixture of complexes [Fe2(CO)6(μ-SC6H2Cl2S)] 1, [Fe2(SC6H2Cl2S)4] 2 and [Fe3(CO)7(μ3-SC6H2Cl2S)2] 3. In the course of the reaction the trimetallic cluster 3 is first formed and then converted into the known dinuclear compound 1 to afford finally the neutral diiron tetrakis(dithiolato) derivative 2. Compounds 2 and 3 have been studi...
Self-assembly of ZnX2 (X = Cl, Br, and I) with N,N',N''-tris(2-pyridinylethyl)-1,3,5-benzenetricarboxamide (L) as a tridentate N-donor ligand yields discrete C3-symmetric trimetallic zinc(II) complexes, [Zn3X6L(MeOH)3]. These form, via π∙∙∙π interactions and NH∙∙∙∙O=C hydrogen-bonds, an ensemble constituting a unique columnar stacking structure in an abab staggered fashion. For this series of c...
The segmental bidentate-tridentate-bidentate ligand L2 reacts with M(II) (M = Cr, Zn) and Ln(III) (Ln = La, Eu, Gd, Tb, Lu) to give the heterotrimetallic triple-stranded helicates [MLnM(L2)3]7+. For M = Zn(II), the isolated complexes [ZnLnZn(L2)3](CF3SO3)7 (Ln = Eu, Tb) display only lanthanide-centred luminescence arising from the pseudo-tricapped trigonal prismatic LnN9 coordination site. For ...
Nanoscale alloys attract enormous research attentions in catalysis, magnetics, plasmonics and so on. Along with multicomponent synergy, quantum confinement and extreme large surface area of nanoalloys offer novel material properties, precisely and broadly tunable with chemical composition and nanoscale dimension. Despite substantial progress of nanoalloy synthesis, the randomized positional arr...
A supported trimetallic nano catalyst and a fixed bed catalytic process have been developed for the conversion of CO2 + H2O (in the form of steam) + 1% H2 to alcohol and propyne The mixture of CO2 +H2O and H2 is passed over Ru:Mn:Ni nano catalyst dispersed on a high surface area antase titanium dioxide catalyst support at 773 K and at atmospheric pressure with the gas space velocity of 6000-700...
