Síntesis y caracterización de nanopartículas magnéticas del tipo Fe3O4/TiO2, efecto del pH en la dispersión y estabilización en soluciones acuosas
(2014)
Magnetic nanoparticles of Fe3O4/TiO2 (core/shell) type were synthesized by a method combining chemical co-precipitation for the initial synthesis of Fe3O4 and sol-gel synthesis for the making of the TiO2 shell film. The ...
Effects of heat treatments on the electrocatalytic activity of Pt-Ru/C for methanol oxidation
(2008-12-01)
The Pt-Ru/C materials of this study were prepared by a microemulsion method with fixed water to surfactant molar ratio and heat treated at low temperatures, to avoid changes in the average particle size, in different ...
