Abstract
A novel, facile, faster, safer, environmentally benign, single-step ultrasound assisted process for the simultaneous synthesis of micro-nano size palladium based transition metal oxides(s) have been successfully developed. The method involved sonolyzing a mixture of palladium salt or palladium metal, water and metal salts. Centrifugation of the slurry was done at 7000 rpm for 10 min to separate slurry into micro size particles and slurry of nano particles. Histograms from particle size analysis showed the presence of bimodal size distribution of both nano micro size particles. Both the micro and nano size samples were subjected to X-ray diffraction analysis to confirm the presence of palladium-copper oxide (Pd-CuO) in both the samples. Size distribution analysis was also done by Dynamic Light Scattering (DLS) technique. Diameters of the Pd-CuO particles were found to be 1.548 µm and 82 nm.
