Fabrication and catalytic properties of Pd and Ce decorated carbon nanotube-TiO2 composite catalysts for low-temperature CO oxidation

- The surface of carbon nanotubes was covered uniformly by TiO2 layer.
- The synergetic effect of CNT and TiO2 promotes the catalytic performance.
- The catalyst prepared by NH3-coordination method had superior activity.
- Pd species was easy to enrich on the surface of catalyst by NH3 coordination.
