In this study, NiO nanoparticles were synthesized using SDS intercalated layered nickel hydroxides as precursors. The precursors were converted into NiO nanoparticles via calcination. The resulting NiO nanoparticles possessed small crystallite size, large specific surface area, and retained the morphology of the precursors.
In the present study, NiO nanoparticles have been synthesized using sodium dodecyl sulfate (SDS) intercalated layered nickel hydroxides as precursors. The precursors were synthesized using homogeneous precipitation method. The SDS intercalated layered nickel hydroxide precursors exhibit hierarchical micro-flower like structures consisting of nanosheets and they were converted into NiO nanoparticles via calcination at 400 degrees C. The SDS intercalated nickel hydroxides and the NiO nanoparticles were characterized using various techniques. The NiO nanoparticles possess small crystallite size, large specific surface area and they retain their original morphology as that of the precursors. The NiO nanoparticles obtained via the calcination of SDS intercalated nickel hydroxides were tested as adsorbent for the removal of congo red from an aqueous solution.
