Studying The Structural Properties of Nickle Oxide Nanoparticles Prepared Using Cellulose Extract by Ultrasonic Method For Photocatalyst Application

Abstract

Nickel oxide nanoparticles (NiO NPs) were prepared using cellulose extract with 1 M NiCH3 salt by ultrasonic method at 600°C. Prepared NiO NPs were characterized by x-ray diffraction (XRD), Filed Emission Scanning Electron Microscopy (FE-SEM). The XRD results confirmed that prepared NiO NPs are crystalline with face center cubic (FCC) and the crystallite sized was 9 nm. FE-SEM measurements show that the particle size of NiO NPs ranges from 40.19 nm to 73 nm with the nano-ball structure. Photocatalytic activity of NiO NPs has been studied through degradation ratio of methylene blue (MB) dye under different illumination time by UV-light. The degradation ratio of MB dye degradation increased from 40% to 90% when illumination time was increased from 15 to 40min.
