The synthesis and characterization of spinel MxCo3-xO4 (M = Mn, Fe, Ni, Cu) nanoparticles was undertaken. Cobalt oxide-based nanoparticles doped with transition metals have a wide variety of potential applications, ranging from new material coatings for concentrating solar power applications to performing as cathode catalysts in fuel cells and metal-air batteries. We have recently demonstrated that MxCo3-xO4 nanoparticles can be prepared using simple, low temperature solution precipitation methods, and that the final size and morphology of the nanoparticle depends on the extent of doping. These materials have been characterized by powder X-ray diffraction (P XRD), high-resolution transmission electron microscopy (HR-TEM), N2 adsorption-desorption, and thermal gravimetric analysis/differential thermal analysis ( TGA/DTA). The synthesis, characterization, as well as some potential applications of these materials, will be presented.
