Colloidal nanoparticles can be controlled in terms of size, shape, composition and crystal structure by adjusting reaction parameters such as the type of precursor, reaction temperature, and reaction time. In particular, the physical, optical, electrical, and magnetic properties of nanoparticles are determined by their microstructures which is manipulated by changing the structural parameters of nanoparticles. In this study, the morphology and crystal structure of NiO nanoparticles were controlled by adjusting reaction parameters during the synthetic procedure. Nanoparticles composed of NiO crystal structures were synthesized by controlling the types and amounts of metal salts, and the morphological variations of nanodots, nanoflowers, and nanoplates were observed. These results suggest that NiO nanoparticles synthesized by colloidal synthesis could possess specific crystal structures and be applicable as electronic devices, energy storage, and electrochemical catalysts. © 2025 Korean Institute of Chemical Engineers.
