Molybdenum trioxide represents a suitable model system for selective oxidation catalysts. According to the well-known redox mechanism the catalytic cycle starts with partial reduction of the oxide catalyst, removal of lattice oxygen, and formation of the oxidation product. Subsequently, the oxide catalyst is re-oxidized by gas-phase oxygen [1]. Hence, oxygen mobility may play a distinct role for the catalytic performance of these catalysts. In this work we aim at modifying oxygen mobility by incorporation of nitrogen in the MoO3 structure. The thus obtained model system shall permit elucidating correlations between reducibility, electrical properties, and catalytic selectivity and activity.
