Sonochemical synthesis, characterization and optical analysis of some metal oxide nanoparticles (MO-NP; M=Ni, Zn and Mn)
چکیده انگلیسی

Some nanosized metal oxide (MO) such as ZnO, NiO and MnO were successfully synthesized by sonochemistry method in solutions at room temperature. The reactants used are (M(Ac)2·2H2O) and sodium hydroxide (NaOH), and H2O/EtOH as a carrier in polyethylene glycol (PEG) template. Some of parameters such as effect concentration of NaOH solution, ultrasound power and sonicating time in growth and morphology of the nanostructures were investigated. The best morphology with smaller particles size and good distribution was obtained by using 0.025 M solution of NaOH and 45 W ultrasound powers in 1 h sonicating time. The particle size of the nanosized metal oxide powders synthesized at room temperature is approximately between 40 and 80 nm. The resulting nanosized powder was characterized by X-ray diffraction (XRD) measurements, Raman, BET, solid state UV–vis and scanning electron microscopy (SEM).
