Abstract

A catalyst for the gas phase oxidation of organic hydrocarbons comprises a multielement oxide which comprises at least one transition meal such as vanadium, wherein the catalyst has a charge transport activation energy Ec at a temperature of 375 to 425° C. of less than 0 kJ/mol. The catalyst serves for preparation of maleic anhydride.
