Beschreibung
Zusammenfassung:	A method of producing an amorphous catalyst or catalyst precursor in the form of a powder having a surface area of from 0.1 m 2 /g to 50 m 2 /g which chemical composition comprises oxygen, carbon, hydrogen, optionally nitrogen, and at least a first and a second further elements, said method comprising: a. Generating an aerosol comprising a mixture of derivatives, said mixture of derivatives comprising at least one derivative per further element, each derivative being a derivative of at least one of said further elements, and at least one of said derivatives being an organic derivative, b. Diluting said aerosol by a gas, and c. Passing said diluted aerosol in a plasma generated between two electrodes, at least one of which being provided with a dielectric, thereby forming an amorphous catalyst or catalyst precursor on one of said electrodes.
