Highly efficient Bi-promoted ZrO2-based materials for non-oxidative propane dehydrogenation.

Surface or bulk promotion of ZrO2-based catalysts with Bi2O3 facilitates the removal of lattice oxygen from ZrO2 under reductive conditions resulting in the formation of coordinatively unsaturated Zr cations. The catalysts demonstrated an industrially relevant propene yield at 600 °C. The results highlight the importance of the usage of suitable promoters for controlling catalyst performance.
