Synthesis of nanosize-controllable copper and its alloys in carbon shells.

چکیده
Nanosize-controllable Cu, Ag, Pd, Ni, CuPd alloy and Cu-Ag bimetal encapsulated in inert carbon shells can be synthesized by carbonization of metal-cyclodextrin complexes with a remarkable capability of experimentally determining the size-dependent melting temperature depression of many metal or alloy nanoparticles.

Synthesis of nanosize-controllable copper and its alloys in carbon shellsw
A very simple method for synthesizing nanosize-controllable (4–40 nm) metals (Cu, Ag, Pd, Rh and Ni) or alloys within carbon shells has been developed. The thickness of the carbon shell that prevents the core metals from being aggregated or oxidized ranges from 3–5 nm. In addition, the synthesized metal nanoparticles exhibit a correlation between dpZ/R (Z = valence of metal and R = atomic radiu...
متن کاملControl Of C/Ti Ratio in Titanium Carbide - Copper Master Alloys Produced by SHS Reactions and its Effect on the Carbide Dispersion In Liquid Copper
Titanium carbide is used as an attractive reinforcement to produce particulate metal matrix composites. One of the problems to use this carbide as a reinforcement in copper-based composites is the lack of wetability in Cu-TiC system. This property improves as the C/Ti ratio in carbide decreases. Problems to use this carbide as a reinforcement in copper-based composites is the lack of wetabiity...

متن کاملElectrosynthesized Reduced Graphene Oxide-Supported Platinum, Platinum-Copper and Platinum-Nickel Nanoparticles on Carbon-Ceramic Electrode for Electrocatalytic Oxidation of Ethanol in Acidic Media
In this work, the electrocatalytic oxidation of ethanol was studied in acidic media at the wholly electrosynthesized nanocomposites: platinum and its alloys (copper and nickel) anoparticles/reduced graphene oxide on the carbon-ceramic electrode (Pt/rGO/CCE, Pt-Cu/rGO/CCE, and Pt-Ni/rGO/CCE electrocatalysts). The electrosynthesized nanocomposites were characterized by scan...
متن کاملIn-flight gas phase growth of metal/multi layer graphene core shell nanoparticles with controllable sizes
In this report, we present a general method for a continuous gas-phase synthesis of size-selected metal/multi layer graphene (MLG) core shell nanoparticles having a narrow size distribution of metal core and MLG shell for direct deposition onto any desired substrate kept under clean vacuum conditions. Evolution of MLG signature is clearly observed as the metal-carbon agglomerates get transforme...
