Mixed Oxides NiO/ZnO/Al2O3 Synthesized in a Single Step via Ultrasonic Spray Pyrolysis (USP) Method

Mixed oxides have received remarkable attention due to the many opportunities adjust their interesting structural, electrical, catalytic properties, leading a better, more useful performance compared basic metal oxides. In this study, mixed NiO/ZnO/Al2O3 were synthesized in single step via ultrasonic spray pyrolysis method using nitrate salts, and temperature effects of process investigated (400, 600, 800 °C). The samples characterized by means scanning electron microscopy, energy-dispersive spectroscopy, X-ray diffraction Raman spectroscopy analyses. results showed Al2O3, NiO–Al2O3 ZnO–Al2O3 systems with spinel phases. Furthermore, peaks supported coexistence oxide phases, which strongly impact overall properties nanocomposite.
