X-ray crystallographic structural Profiling of Polyvinyl Alcohol (PVA) caped Nickel Oxide Nanoparticle

• 87 % pure NiO phase with crystallinity of 47.21 %. • Hexagonal structure with lattice parameters of a = b = 2.955 Å, c = 7.2434 Å. • Angular parameters α=β= 90 ° and γ= 120 °. • Average dislocation density of 0.00206 nm⁻², lattice strain of 0.27 %. • Uniform spherical morphology with average particle size 48 nm. A unique simple co-precipitation method was developed for synthesizing highly crystalline nickel oxide nanoparticles (NiO NPs) where poly vinyl alcohol (PVA) solution as capping agent. Rietveld refinement analysis explored whole powder pattern fitting (WPPF) method confirmed resulting nanoparticles (NPs) consist of 87 % pure NiO phase. X-ray diffraction (XRD) analysis revealed a distinct hexagonal NiO crystalline phase, with lattice parameters…
