Novel Electroless Plating of Ruthenium for Fabrication of Palladium-Ruthenium Composite Membrane on PSS Substrate and Its Characterization
This paper focused on a novel method of electroless plating ruthenium (Ru) on solid or porous substrates like porous stainless steel (PSS) discs or ceramic tubes. A novel complexing plating bath of Ru was developed. It is proven that Ru can be deposited directly on these substrates by the bath at a temperature of 328 K and strong alkaline environment. TGA, SEM, EDX and XRD confirmed the success...
متن کاملNitrene-functionalized ruthenium nanoparticles†
Ruthenium nanoparticles protected by ruthenium–nitrene p bonds were prepared by refluxing ‘‘bare’’ ruthenium colloids (2.12 0.72 nm in diameter) and 4-dodecylbenezenesulfonyl azide in secbutylbenzene. Thermogravimetric analysis (TGA) of the resulting nanoparticles showed that on average there were about 84.1 ligands on the nanoparticle surface. XPS studies showed a 1 : 1 atomic ratio between ni...
متن کاملAlkyne-Protected Ruthenium Nanoparticles†
Stable ruthenium nanoparticles protected by 1-octynyl fragments were synthesized by a wet chemical method. Transmission electron microscopic measurements showed that the resulting particles exhibited an average core diameter of 2.55 ( 0.15 nm with well-defined Ru crystalline lattice fringes. Because of the formation of RusCt bonds, the CtC vibrational stretch was found in FTIR measurements to r...
متن کاملCarbene-Functionalized Ruthenium Nanoparticles
Stable ruthenium nanoparticles were synthesized by protecting the particles with diazo molecules that reacted readily with the ruthenium surface forming RudC carbene bonds, as manifested in Fourier transform infrared and 1H NMR measurements. The resulting particles, with the core diameter averaged at 2.12 ( 0.72 nm as determined by transmission electron microscopic measurements, showed a Mie sc...
متن کاملPreparation of Ruthenium(I1) and Ruthenium(II1) Myoglobin and the Reaction of Dioxygen, and Carbon Monoxide, with Ruthenium(I1) Myoglobin*
Ruthenium myoglobins have been prepared by the reconstitution of horse heart apomyoglobin with either ruthenium(I1) or ruthenium(II1) mesoporphyrin IX (MpIX) derivatives. The ruthenium(I1) and -(III) myoglobins (RuMb and RuMb+, respectively) contain one ruthenium porphyrin/heme binding site; the species are readily interconverted using dithionite for reduction and bromine for oxidation. RuMb bi...
