A Simple New Method to Synthesize Nanocrystalline Ruthenium Dioxide in the Presence of Octanoic Acid As Organic Surfactant
Ruthenium dioxide nanoparticles (RuO2 ) with an average particle size of 50 nm are readily synthesized from RuCl3.xH2O via the precipitation process in the presence of in-situ sodium octanoate as anionic surfactant. The phase composition, morphology, lattice parameters and size of nanoparticles in these products are characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffrac...
متن کاملStructural Characterization and Ordering Transformation of Mechanically Alloyed Nanocrystalline Fe-28Al Powder
The synthesis of nanocrystalline Fe3Al powder by mechanical alloying as well as the structural ordering of the synthesized Fe3Al particles during the subsequent thermal analysis were investigated. Mechanical alloying was performed up to 100 hours using a planetary ball mill apparatus with rotational speed of 300 rpm under argon atmosphere at ambient temperature. The synthesized powders were cha...

متن کاملEx-situ studies on calcinations of structural, optical and morphological properties of post-growth nanoparticles CeO2 by HRTEM and SAED
Nanocrystalline particles of Cerium Oxide (CeO2) have been prepared by the chemical precipitation method using Cerium nitrate and Urea with a molar ratio of 1:2. The results revealed that the formation of CeO2 fine particles is influenced by molar ratio of metal nitrates to fuel. Well faceted CeO2 nanoparticles, were synthesized by thermal-assisted dissociation ...
