Binary copper and manganese oxide nanoparticles supported OMS-2 for enhancing activity and stability toward co-oxidation reaction at low temperature

CuO, CuMnOx and MnOx catalysts were anchored on the manganese oxide support with the structure of octahedral molecular sieves (OMS-2), which were synthesized using MnSO4 and KMnO4 as precursors by refluxing under acidic conditions or impregnation. The catalysts were then tested for CO oxidation.
