PdO/PdO2 mixed oxides nanoparticles-functionalized ZnO nanowires

Abstract

The invention relates to the technology of the metal oxides, in particular to the electrochemical one-step synthesis of Pd and PdO/PdO2 mixed oxides nanoparticles-functionalized ZnO nanowires at temperature of 90 ºC. The electrolyte solution consist of 0.2 mM ZnCl2 + 0.1 M KCl + PdCl2 1.5 μM and applied potential of – 0.51 ÷ – 0.7 V. The oxidation of Pd nanoparticles to PdO/PdO2 mixed oxides was achieved by two-step thermal annealing (at 150 to 250 ºC with growth rate of 1 ºC/min, and then maintaining at 250 ºC during 12 h). The developed technology allows to essential reducing in technological steps of high performance nanomaterials synthesis.
