Urea-stabilized air-stable Pt nanoparticles for thin film deposition.
نویسندگان
چکیده
The reduction of [Pt(COD)(CH3)2] with CO in the presence of hexadecylamine (HDA) and oleic acid (OlAc) leads to amine carbonylation and formation of an air-stable colloidal solution of N,N'-bis(hexadecyl)urea-stabilized Pt(0) nanoparticles. These air-stable colloidal solutions can be used to form thin films of Pt nanoparticles on a silicon substrate.

Characterization of nanostructured SnO2 thin film coated by Ag nanoparticles
Nanostructured SnO2 thin films were prepared using Electron Beam-Physical Vapor Deposition (EB-PVD) technique. Then Ag nanoparticles synthesized by laser-pulsed ablation were sprayed on the films. In order to form a homogenous coated of SnO2 on the glass surface, it was thermally treated at 500°C for 1 h. At this stage, the combined layer on the substrate was completely dried for 8 h in the air...

Hydrogen sensing of thick films of nanoparticles of pristine, 0.2, 1.0 and 2.0 atomic percentage of Pt concentration doped ZnO were investigated. ZnO nanoparticles doped with 0.2-2.0 at.% Pt were successfully produced in a single step by flame spray pyrolysis (FSP) technique using zinc naphthenate and platinum(II) acetylacetonate as precursors dissolved in xylene. The particle properties were a...
متن کاملTemperature-dependent 2-D to 3-D growth transition of ultra-thin Pt films deposited by PLD
During the growth of thin metal films on dielectric substrates at a given deposition temperature Td, the film’s morphology is conditioned by the magnitude and asymmetry of upand downhill diffusion. Any severe change of this mechanism leads to a growth instability, which induces an alteration of the thin film morphology. In order to study this mechanism, ultrathin Pt films were deposited via pul...
متن کاملELECTROCHEMICAL BEHAVIOR OF GC, Pt AND Au ELECTRODES MODIFIED WITH THIN FILM OF COBALT HEXACYANOFERRATE
0A thin film of cobalt hexacyanoferrate (CoHCF), an analogue of mixed-valence Prussian blue, was deposited electrochemically on the glassy carbon, platinum and gold electrode surfaces in 0.5M KC1 solution. The electrochemical behavior of these modified electrodes show three couples of redox peaks by CV in a supporting electrolyte solution of 0.5M NaCl, whereas for Au modified electrode only ...
