Journal ArticleDOI
Superparamagnetism and magnetic properties of Ni nanoparticles embedded in SiO 2
Fabio C. Fonseca,Gerardo F. Goya,R. F. Jardim,Reginaldo Muccillo,Neftalí L. V. Carreño,Elson Longo,Edson R. Leite +6 more
TL;DR: In this article, a detailed characterization of the magnetic properties of Ni nanoparticles embedded in a SiO2 amorphous matrix was performed using a modified sol-gel method which resulted in Ni particles with average radius ;3 nm, as inferred by TEM analysis.
Journal ArticleDOI
Recoverable rhodium nanoparticles: Synthesis, characterization and catalytic performance in hydrogenation reactions
TL;DR: In this article, the first magnetically recoverable Rh(0) nanoparticle-supported catalyst with extraordinary recovery and recycling properties is reported. But it does not require filtration, decantation, centrifugation, or any other separation technique thereby, overcoming traditional time and solvent-consuming procedures.
Journal ArticleDOI
Magnetic Fluids Based on γ-Fe2O3 and CoFe2O4 Nanoparticles Dispersed in Ionic Liquids
TL;DR: In this article, the surface modified NPs have proved to form stable dispersions in BMIBF4 in the absence of water and behave like a magnetic ionic liquid, and the MILs have been characterized by Raman spectroscopy, magnetic measurements, and DSC.
Journal ArticleDOI
Magnetic properties of Fe3O4 nanoparticles coated with oleic and dodecanoic acids
V. B. Barbeta,R. F. Jardim,Pedro Kunihiko Kiyohara,Fernando Bacci Effenberger,Liane M. Rossi +4 more
TL;DR: Magnetic nanoparticles (NP) of magnetite (Fe3O4) coated with oleic acid and dodecanoic acid (DA) were synthesized and investigated through Transmission Electron Microscopy (TEM),magnetization M, and ac magnetic susceptibility measurements as discussed by the authors.
Journal ArticleDOI
Preparation of recoverable Ru catalysts for liquid-phase oxidation and hydrogenation reactions
TL;DR: In contrast to most supported catalysts, these new developed catalysts for oxidation and hydrogenation reactions were prepared using nearly the same synthetic strategy, and are easily recovered by magnetic separation from liquid phase reactions.
