Well-dispersed palladium supported on ordered mesoporous Co3O4 for catalytic oxidation of o-xylene

- Pd loading of Pd/Co3O4(3D) and Pd/Co3O4(3DL) was prepared by two different methods.
- Pd/Co3O4(3D) shows much better activity than Pd/Co3O4(3DL) for o-xylene oxidation.
- Mesostructure and highly dispersed PdO are the reason for high catalytic activity.
- Nanocasting is useful for preparing metal highly dispersed mesoporous catalysts.
