synthesis and characterization of a bi-oxide nanoparticle zno/cuo by thermal decomposition of oxalate precursor method

in the present work, we report the synthesis of binary nano metal oxides such as zinc /copper oxide via novel dry synthetic methods such as thermal decomposition of oxalate precursor. the synthesis route involves facile solid-phase mechanochemical activation of a physical mixture of simple copper/zinc salts and oxalic acid, followed by calcination of the as-ground oxalate precursors at 450◦c. x-ray powder diffractometry (xrd), infrared spectroscopy (ftir), and scanning electron microscopy (sem) were used to the thermal spectroscopic, structural, morphological characterization and surface area determination of the product respectively . an average nanocrystallite size of 5.0 nm was obtained for zn/cu, as estimated by the scherrer’s equation.
