摘要：

NiO nanoparticles were prepared on the silica surface by adsorption phase synthesis. The adsorption and preparation experiments of different reactants were designed to select suitable reactants for the synthesis of NiO particles. Using X-ray Diffraction (XRD) and transmission electron microscopy (TEM) analyses the differences in morphology and grain size of NiO particles prepared under various conditions were characterized. When the quantity of Ni(NO3)(2) exceeded 2.0 mmol, the conglomeration of NiO particles became obvious. While the temperature increased from 0 to 40 degrees C, the elevation of reaction rate and supersaturation in the adsorption layer resulted in appearance of NiO particles with smaller size. When the temperature exceeded 40 degrees C, the attenuation of the adsorption layer led to the appearance of the blank silica without NiO particles.
