The structure and properties of nanocomposites of poly(ethylene oxide), with Ag and Au nanoparticles, surface modified with a 1:1 (by volume) oleylamine/oleic acid mixture, were investigated via transmission electron microscopy, scanning electron microscopy, thermogravimetric analysis, differential scanning calorimetry (DSC), infrared spectroscopy, dynamic mechanical analysis, and static mechan...

CH3NH3PbI3 capped PbS colloidal quantum dots have been successfully fabricated by solid-state ligand exchange from oleate and oleylamine capped PbS. The optimal solar cells made by layer-by-layer solution deposition give a high power conversion efficiency of 4.25% with an impressive short-circuit photocurrent density of 24.83 mA cm-2.

GeTe octahedra were prepared by reaction of equimolar amounts of GeCl2·dioxane and Te(SiEt3)2 in oleylamine, whereas a slight excess of the Te precursor yielded GeTe octahedra decorated with elemental Te nanowires, which can be removed by washing with TOP. The mechanism of the GeTe formation is strongly influenced by the solvent. The expected elimination of Et3SiCl (dehalosilylation) only occur...

A new strategy for the synthesis of fluorescent monodispersed 2-dimensional (2D) CdSe/CdS core/shell hexagonal platelet nanocrystals has been demonstrated. Because of the stronger affinity of the -NH2 group of oleylamine to the (0001Se) facet comprising three dangling bonds in CdSe seeds, oleylamine acts as the sole surfactant responsible for hindering the growth of the CdS shell in the 0001 an...

The precursor conversion chemistry and surface of Cu3N Cu3PdN nanocrystals are unknown or contested. Here, we first obtain phase-pure, colloidally stable nanocubes. Second, elucidate the pathway by which copper(II) nitrate oleylamine form Cu3N. We find that is both a reductant nitrogen source. Oleylamine oxidized to primary aldimine, reacts further with excess secondary eliminating ammonia. Amm...

Chemicals: Thallium (I) nitrate (TlNO3, 99.9%), tetrabutylammonium iodide (TBAI, 99%), tetrabutylammonium bromide (TBABr, 98%), 1-octadecene (ODE, tech. 90%), oleylamine (OLA, tech. 70%), oleic acid (OA, tech. 90%), potassium bromide (KBr, 99%) and fluorescein sodium salt (98.5-100.5%) were purchased from Sigma-Aldrich. Hexane (98%), toluene (99.5%), 1-butanol (99.5%) and acetonitrile (99.8%) w...

The shape of Pd nanocrystals (NCs) can be controlled by combination of oleylamine (OAm) and alkylammonium alkylcarbamate (AAAC), and Pd spheres, tetrahedra and multipods have been synthesized. The multipods and tetrahedra are much more active than the spheres for hydrogenation reactions.

Hollow Pd/Sn bimetallic nanocrystals were fabricated by a fast one-pot strategy in an oleylamine system. This method produced a fine single crystalline bimetallic hollow nanostructure. The process and influencing factors of the reaction are also discussed in this work. Bimetallic nanoparticles possessing special hollow structures with single-crystalline nature are expected to have particular el...

Ultrathin copper oxide (CuO) nanorods with diameters of ∼3.6 nm were obtained in one step using oleylamine (OAm) as both the solvent and the surface controller. The oriented attachment is responsible for the formation of the ultrathin CuO nanorods. Furthermore, this ultrathin nanostructure catalyst exhibited excellent activity and high styrene oxide yields in styrene epoxidation.
