Microwave-induced fabrication of copper nanoparticle/carbon nanotubes hybrid material
Leelaviwat, N.,Monchayapisut, S.,Poonjarernsilp, C.,Faungnawakij, K.,Kim, K.S.,Charinpanitkul, T. Elsevier 2012 CURRENT APPLIED PHYSICS Vol.12 No.6
Copper nanoparticle/multi-walled carbon nanotube (MWCNT) hybrid material could be fabricated by microwave irradiation to a suspension of MWCNTs dispersed in copper precursor with the presence of ethylene glycol. Microscopic and spectroscopic analyses could confirm the uniform dispersion of copper oxide nanoparticles hybridized on the outer surface of MWCNTs. Reduction of Cu<SUP>2+</SUP> ions to Cu<SUB>2</SUB>O and Cu nanoparticles was ascribed to functional groups which were generated after the precursor was irradiated by microwave. Sufficient irradiation time of 5 min or longer played an important role to induce the agglomeration of copper oxide nanoparticles on the MWCNT surface.
