Cu/ZnO system in nanotube by a CVD method using [Cu(OCH(Me)CH2NMe2)2] and Et2Zn as precursor

Abstract

The Cu/ZnO system is the basis of industrial methanol synthesis and important component of fuel-cell technologies. We have made the ternary system Cu/ZnO/Al2O3nanotube by CVD method. We present a synthetic approach toward alloyed Cu/ZnO nanoparticles in the Al2O3nanotube using [Cu(OCH(Me)CH2NMe2)2] and Et2Zn as precursors. The Cu/ZnO/Al2O3 nanotubes are analyzed by using TEM and EDX. These analytical data suggest that alloying between zinc and copper takes place, revealing crystalline phase of copper nanoparticles(2~3nm) deposited onto ZnO.
