It is a problem to be solved by the present invention to provide an oxidation catalyst which, in oxidation of a compound, can efficiently effect oxidation using oxygen in the air as an oxygen source and can be used repeatedly. The above-mentioned problem was solved by an activated carbon in which the BET specific surface area S determined by a nitrogen adsorption method and the amount of surface oxygen which will leave in the form of carbon monoxide O(% by weight) satisfy formula (I) 4000&#x3c;S&#xd7;O. By using this oxidation catalyst, it is possible to oxidize a compound having an oxidizable carbon atom linked directly to an aromatic ring, including a heterocyclic ring, to a corresponding aldehyde or keto compound, or to oxidatively dehydrogenate a hydrogen-containing compound to form an unsaturated bond or a cyclic compound, or to oxidatively and dehydrogenatively form a nitrogen-containing heterocyclic ring from an aryl aldehyde and a compound having a pair of adjacent carbon atoms, one of the carbon atoms having an amino group and the other having an amino, hydroxyl or mercapto group.
