A selective preparation and the formation mechanism of hexagonal and cubic CoO nanoparticles from the reaction of (CoA2) (acac = acetyla- cetonate) and amine have been investi- gated. CoO nanoparticles with a hexag- onal pyramidal shape were yielded

Pure rocksalt (c-CoO) and wurtzite (h-CoO) phases of cobaltous oxide (CoO) have been selectively prepared through thermodynamically and kinetically controlled reactions of a single molecular precursor Co(acac)3 (acac: acetylacetonate), respectively.

The highly monodisperse PtRu (1:1) colloidal nanoalloy was prepared by the co-reduction of Pt(acac)2 and Ru(acac)3 precursors, deposited on a Vulcan carbon (Vc) support and subsequently treated by acetic acid to generate active PtRu/Vc catalyst, whic

Highly crystalline, phase- and size-controlled CoO nanocrystals of hexagonal and cubic phases have been prepared by thermal decomposition of Co(acac)3 in oleylamine under an inert atmosphere. Kinetic and thermodynamic control for the precursor format

Monodisperse Pt and PtRu/C(60) hybrid nanoparticles with controlled diameters were synthesized by the reduction of metal precursors in the presence of C(60); the resulting metal/C(60) hybrid nanocatalyst exhibited a remarkable enhancement of methanol
