| 摘要 |
The present invention provides a process for producing particles comprising mixing, in a substantially water-free environment, at least one metal compound of the formula M(O2CR)nX(m-n)Lp wherein M is an electropositive element of Groups 1-15, each X is independently selected from the group consisting of O1/2, F, Cl, Br, I, OR, O2CR, NR2, and R, each R is independently a hydrocarbyl group, each L is independently a Lewis base ligand, n is equal to ½ the oxidation state of the metal M in the product particle, m is equal to the oxidation state of M in the compound M(O2CR)nX(m-n)Lp and p>=0; at least one surfactant; and at least one solvent wherein the mixture is thermally treated for a time sufficient to convert the at least one metal compound into particles of the corresponding oxide having sizes in a range between about 0.5 nanometers and about 1000 nanometers.
