Preferential oxidation of CO in H2 stream over a highly efficient and stable MnOx-Co3O4 catalyst
Introduction The preferential oxidation (PROX) of CO in H2-rich stream is one of the most efficient routes for the production of pure H2 for the PEM fuel cell. The development of catalysts based on non-noble transition metal oxides has attracted much attention from the economical viewpoint. Co3O4 may be promising because it exhibits good performance for the oxidation of CO at lower temperatures 1. However, there are only a few studies on the PROX of CO in H2 over Co3O4-based catalysts 2, and these catalysts undergo deactivation during the reaction. Herein, we report our recent finding that the addition of MnOx to Co3O4 can significantly enhance both the activity and the stability of Co3O4. The structure-performance correlation will be discussed in detail.
