| 摘要 | The invention relates to methods for producing hydrophobized, doped or non-doped mixed metal oxide nanoparticles or doped metal oxide nanoparticles by flame spray pyrolysis, wherein a combustible precursor solution A, containing at least two metal alkyloates of general formula Me(OOC—R)x with differing metals Me, or a combustible precursor solution B containing at least one metal alkyloate of general formula Me(OOC—R)x and at least one metal salt containing a metal ion Me and at least one metal salt containing a metal ion Me, with Me selected from metal ions of the subgroups of the periodic system of the elements, with R=alkyl or aryl, wherein the alkyl chain is branched or straight, and wherein x corresponds to the oxidation step of the metal ion, is used in stoichiometric excess relative to a quantity of oxygen, and wherein a combustion ratio c of 3.5 bis 0.4 is established, and hydrophobized nanoparticles and the use thereof. | ||||||
