Nanocrystalline copper oxide (CuO) particles were
precipitated by using different sources of copper salts and oxalic acids. The transformation to
monoclinic CuO is achieved by heating the copper precipitate at 300 degrees C for 4 h. Dice-like
and flower-like structures were obtained from the effects of by-product's acidity to the
morphology of copper oxalate (Cu(C2O4)). The particle sizes of all samples, determined by
transmission electron microscopy (TEM), were in the range of 10-30 nm. 0.5% CuO doped ZnO (CuO-
ZnO) nanophotocatalysts were successfully prepared by mixing synthesized CuO nanoparticles with
synthesized ZnO in absolute methanol. No significant changes in morphology were observed between
the undoped and doped ZnO except for a higher surface area obtained for CuO doped ZnO. The doping
of CuO on ZnO also resulted in enhanced photocatalytic performance of ZnO in the photodegradation
of methyl orange dye.
