    초록 Nano metal particles are of considerable interest for a variety of applications. High temperature heating or the reducing gas have been widely accepted to be crucial for reducing late transition metal oxide. Recently, Kim and Ehrman reported that addition of alcohol could act also as a safe reducing agent. While producing copper nanoparticles following their method, we found that Cu nanoparticles experienced at all the time morphological change from shell-like to near solid, which was confirmed by EDX measurement with TEM. Rise in reaction temperature results in the same crystalline phase transition accompanying the morphology change. XRD analysis revealed the shift of lattice constant of Cu to the increasing direction with rising reaction temperature. This may imply the Cu nanocrystallite bonded to oxide at atomic scale.
