Low Temperature Chemical Synthesis of Nickel Oxide Microflower and Study of its Optical and Thermal Properties

R. Chopra, U. K. Ghorai, Diptonil Banerjee

Abstract


A simple rout for the synthesis of flower like nickel oxide nanostructure has been reported using nickel sulphate and potassium per-sulphate as precursor. Efforts were made to see the effect of persulfate amount on different properties of the materials thus two samples were synthesized with different amount of per-sulphate precursors. The as prepared samples were characterized by x-ray diffraction, field emission scanning and transmission electron microscope, thermal gravimetric and differential thermal analytical study. Also the samples were characterized further with the help of Fourier transformed infrared spectroscopic study as well as UV-Vis spectroscopic study taken in reflection mode. XRD confirms the proper phase formation of the sample whereas the microscopic analysis has given an idea abort the morphological as well as dimensional information. TG-DTA study shows the thermal stability of the sample whereas FTIR study gives the information regarding the different bonding present in the sample. Reflection study shows that due to change in the precursor amount there is a marked difference in the reflection spectra as well as optical gap of the sample.
