摘要：

Ag-OMS-2 nanorods were synthesized by a simple solid-state reaction of AgMnO4 with manganese acetate. The nanorods had a diameter of about 8 mn and lengths of 50-150 nm with the co-existence of micropores and mesopores. Structural analysis revealed that the nanorods were amorphous but exhibited lattice fringes of Ag-hollandite structure. The silver species presented as Ag+ and the average oxidation state of manganese was 3.7. Most importantly, the Ag-OMS-2 nanorods showed quite high catalytic performance for CO oxidation with 100% CO conversion at 90 degrees C, mainly because of the significantly enhanced oxygen activation and CO adsorption with the presence of Ag+ in the tunnels.
