SYNTHESIS AND CHARACTERIZATION OF MORPHOLOGY DEPENDENT NICKEL OXIDE CATALYST TO AID HYDRODEOXYGENATION OF PHENOL TO BIO-FUELS

Various nickel oxide (NiO) nanostructures were prepared in different bases via
hydrothermal method. The bases used in this research paper are sodium hydroxide,
ammonia, potassium hydroxide and sodium carbonate. NiO nanoparticles, nanorods,
nanohexagonal, nanocubic, nanopentagon and nanocuboid with different sizes were
obtained. The obtained nanoparticles have been characterized by means of X-ray
powder diffraction (XRD), scanning electron microscopy (SEM), transmission
electron microscopy (TEM) and RAMAN. A possible growth mechanism is
proposed including the formation of hierarchial microspheres aggregated from nuclei
