Abstract

Process for the synthesis of nanoparticles comprising oxidation sensitive metals, in particular copper comprising the following steps: Preparation and nucleation of citrate-capped Metal-hydroxide nanoparticles, reduction of the intermediate citrate-capped Metal-hydroxide nanoparticles to Metal0 by reduction via NaBH4 Cu0 nanoparticles with narrow size distribution are obtained by NaBH4 Li-induced reduction of CUCI2 2H2O in diethylene glycol. The course of the reaction essentially involves an intermediate formation of Cu(OH)2 nanoparticles as well as the presence of citrate to control the nucleation of almost monodisperse and non-agglomerated Cu0 nanoparticles. The citrate-capped Cu0 nanoparticles of the invention are surprisingly stable against air oxidation. Via simple solvent evaporation, porous Cu0 thin-films are prepared on glass substrates that exhibit bulk-like sheet resistances of 0.23 - 0.42 Ωϛ after vacuum sintering at 250 °C (bulk-Cu sheet under similar conditions with: 0.3 Ωϛ). With these features the as-prepared, citrate-capped Cu0 nanoparticles become highly relevant to electronic devices in particular thin-film electronics, thin-film sensors and high-power batteries.
