    摘要: The present invention is directed to novel sol-gel methods in which metal oxide precursor and an alcohol-based solution are mixed to form a reaction mixture that is then allowed to react to produce nanosized metal oxide particles. The methods of the present invention are more suitable for preparing nanosized metal oxide than are previously-described sol-gel methods. The present invention can provide for nanosized metal oxide particles more efficiently than the previously-described sol-gel methods by permitting higher concentrations of metal oxide precursor to be employed in the reaction mixture. The foregoing is provided by careful control of the pH conditions during synthesis and by ensuring that the pH is maintained at a value of about 7 or higher.
