    Abstract: The invention relates to a method for producing amorphous and/or crystalline metal (mixed) oxides, especially metals of the third to fifth main group or subgroups of the periodic table, the mean particle diameters of the (mixed) oxides being between 1 and 500 nm, especially between 1 and 100 nm. The ions of the metal(s) from which the (mixed) oxide is to be produced and which are dissolved in an organic electrolyte are electrochemically reduced on a cathode in an electrolysis device fitted with a cathode and an anode, in the presence of an oxidation agent. The cathode space (cathode half-cell) and anode space (anode half-cell) are separated by a porous separating wall or barrier (diaphragm) which enables the passage of a flow, i.e. which is permeable to cations and anions, but renders difficult, especially prevents, the passage of elementary halogens from the anode space to the cathode space.
