The synergistic catalytic effect between graphene oxide and three-dimensional ordered mesoporous Co3O4 nanoparticles for low-temperature CO oxidation

In this paper, the 3D Co3O4/GO catalyst showed fine 3D ordered mesoporous structures. The synergistic effect of graphene oxide and Co3O4 made the 3D Co3O4/GO catalyst with the ethanol as solvent showed excellent catalytic activity and the cycle stability. The solvent influenced catalytic activity by changed the ratio of Co3+ and numbers of contained-oxygen groups. Based on this, the 3D Co3O4/GO(ET) catalyst presented superior catalytic activity and cycle stability.237
