We applied a method of plasma arc synthesis to study effects modification the fluorite phase ceria by tin ions. By sputtering active components (Pt, Ce, Sn) together with carbon from graphite electrode in helium ambient we prepared samples complex highly defective composite PtCeC and PtCeSnC oxide particles stabilized matrix carbon. Subsequent high-temperature annealing oxygen removes causes formation catalysts Pt/CeOx Pt/CeSnOx for CO oxidation. In presence Sn, X-Ray Diffraction (XRD)...
Nanowires of silicon oxide SiO x ( ≤ 2) were synthesized from a mixture monosilane and hydrogen (helium, argon) by gas‐jet electron beam plasma chemical vapor deposition (GJ EBP CVD) method with simultaneous supply oxygen into the vacuum chamber. The synthesis was performed on monocrystalline glass substrates coated micron‐sized particles tin catalyst. In particular, aligned arrays nanowire bundles (microropes) (argon). A bundle amorphous nanowires, each which is about 15 nm in diameter,...

Composites based on graphene and nanosized silicon have recently been of interest in various applications. This paper reports a new method synthesising graphene‐nano composite material by spraying mixture quartz‐graphite using an electric arc. The structure composition the materials obtained depends synthesis conditions. quality concentration quartz load. Higher SiO 2 content leads to production more structured graphene. In this case, is present form carbide nanoparticles deposited planes....
Electric arc discharge is a straightforward and attractive method for the synthesis of nanomaterials with unique properties. When electric sputtering composite tin-carbon electrode occurs in an inert gas medium, material formed that composed spherical tin nanoparticles surrounded by carbon shell. The themselves have core-shell structure crystalline core amorphous Such has four times reduced enthalpy melting due to presence phase. However, processes leading formation nanostructures are not...
The electroconductive and magnetic properties of nanomaterials containing carbon nanoforms synthesised for electrocatalytic, electrochromic ferrofluid applications, etc., are interest to researchers. This article aims understand the physical effects influencing materials by arc discharge. nanomaterial formation processes leading structures also discussed. Arc discharge between graphitic electrodes results in emergence a fan‐shaped jet helium carbon. gasdynamic temperature parameters depend...
The nanowires of the silicon oxide SiO x ( ≤ 2) are synthesized on an indium catalyst by gas‐jet electron beam plasma chemical vapor deposition (GJ EBP CVD) method using a monosilane‐argon‐hydrogen mixture with simultaneous supply oxygen into vacuum chamber. arrays aligned microropes (bundles) formed at substrate temperatures 200–335 °С. At temperature 160 °С cocoon‐like structures synthesized. obtained results explained within synthesis model suggested previously. Fourier transform infrared...
