ABSTRACT:
There are provided oxidation catalysts having a specific surface ranging m 12 to 100 m.sup.2 /g and containing as their main constituent either an oxide of cobalt or an oxide of bismuth. The catalysts further contain a promoter in the form of a rare earth oxide or thorium oxide, and they may also contain at least one oxide of manganese, iron, magnesium, chromium or niobium. Such catalytic compositions can be used for the oxidation of ammonia in a solid bed or in a fluidized bed.
