Abstract

Copper nanoparticles were successfully synthesised through microwave irradiation of a copper-oxide particle precursor dispersed in tetraethylene glycol. Initial results obtained after 4–6 min of irradiation, without the use of a surfactant, indicated nanoparticle aggregation and particle-size bimodality by incomplete reduction. However, the said aggregation and bimodality were observed to be significantly suppressed with accelerated reduction upon addition of an alcohol-type surfactant. Consequently, Cu nanoparticles measuring 74 and 79 nm in size were successfully synthesised by performing short irradiations lasting 3 and 4 min, respectively.
