概要

Effect of Calcination Time on Structural, Optical and Antimicrobial Properties of Nickel Oxide Nanoparticles

Shanaj BR and John XR

Nickel oxide nano crystallites were synthesized using Nickel [II] Chloride and Sodium hydroxide. The Thermo Gravimetric and Differential Thermo gravimetric (TGA/DTA) analysis were done to study the thermal behavior of the as synthesized sample Ni(OH)2. The peak at 290°C in DTA may be related to the decomposition of Ni(OH)2 into NiO. The structural, optical properties, morphology and composition of NiO nano particles (NPs) were studied by various techniques such as XRD, FTIR, UV-Vis, PL, FESEM and EDAX. The antimicrobial activity were carried out against Gram positive and Gram negative bacteria and NiO NPs showed inhibitory activity in both strains of bacteria with excellent selectivity against Gram-positive bacteria.
