Synthesis of Cuprous Oxide by Thermal Treatment in Liquid Paraffin

Cu2o nanoparticles were synthesized by  thermal  treatment  in  liquid paraffin  without  any  inert  gas  protection  using  nano  structures  of schiff base copper (ii) complex (1) as precursor. liquid paraffin was used  as  solvent  and  reductant.  span  80 was  applied  to  control  the morphology  of  cuprous  oxide  nanoparticles. the  nano  structure  of the  complex was  characterized by x-ray  diffraction measurements, uv–visible  spectroscopy  and  fourier  transforms  infrared spectroscopy. thermal stability of cu complex in  its nano size form has  also  been  studied  by  thermal  gravimetric  and  differential scanning  calorimetry  analysis.  the  obtained  cuprous  oxide nanoparticle has been characterized by xrd measurements and ft-ir  spectroscopy.  the  morphology,  structure  and  size  of  the  nano structure  of  1  and  cu2o  are  investigated  by  scanning  electron microscopy. the  resulted cuprous oxide nanoparticles with average diameter  about  30-40  nm  were  obtained  and  they  have  uniform morphology and stable when exposed to air.
