Nanostructured Materials Prepared by Surface-Assisted Reduction: New Catalysts for Methane Oxidation

ACS Appl Mater Interfaces. 2015 Sep 2;7(34):19268-73. doi: 10.1021/acsami.5b05189. Epub 2015 Aug 19.


Cerium formate hollow spheres and cerium hydroxycarbonate nanorods with residual formate groups are effective for reducing palladium(II) salts onto their surfaces. Calcination of the new materials obtained by this surface-assisted reduction method gives highly active PdO/CeO2 nanostructures with Pd well dispersed on the substrate. Temperature-programmed oxidation experiments showed that these nanomaterials are good catalysts for the low-temperature oxidation of methane, with 50% conversion temperatures (T(50%)) at ∼300 °C.

Keywords: cerium oxide; methane oxidation; nanostructured materials; palladium; surface-assisted reduction.
