| Abstract: | ZnO/Al2O3 composite nanoparticles were prepared by a nonhydrolytic sol-gel method, using anhydrous ZnCl2 and AlCl3 as precursors, acetone as solvent, and oleic acid as oxygen donor. X-ray diffraction（XRD）, infrared spectrum（IR）, transmission electron microscopy（TEM） and ultraviolet-visible spectrophotometer were employed to characterize the particles prepared. Results showed that the prepared particles were amorphous ZnO/Al2O3 composite nanoparticles with the average diameter of 61 nm. Spherical and oil-soluble ZnO/Al2O3 composite nanoparticles were in mono-dispersion state, and uniformly and steadily dispersed in No.20 mechanical oil. |
