Co3O4 morphology in the preferential oxidation of CO

Electrochemical Preferential Oxidation of CO in Reformate

Ultrathin Co3O4 nanowires with high catalytic oxidation of CO.

Ultrathin Co(3)O(4) nanostructures with high catalytic oxidation of CO were synthesized by heating cobalt foils under atmospheric conditions. The Co(3)O(4) nanostructures were selectively exposing (111) planes composed of plenty of Co(3+) cations. We observed ultrahigh catalytic oxidation of CO in Co(3)O(4) nanowires with about 3 nm diameter.

Effect of Reactor Heat Transfer Limitations on Co Preferential Oxidation

Our recent studies of CO preferential oxidation (PrOx) identified systemic differences between the characteristic curves of CO conversion for a microchannel reactor with thin-film wall catalyst and conventional packed-bed lab reactors (m-PBR’s). Strong evidence has suggested that the reverse water-gas-shift (r-WGS) side reaction activated by temperature gradients in m-PBR’s is the source of the...

Enhancing Catalytic CO Oxidation over Co3O4 Nanowires by Substituting Co with Cu

Co3O4 is an attractive earth-abundant catalyst for CO oxidation, and its high catalytic activity has been attributed to Co cations surrounded by Co ions. Hence, the majority of efforts for enhancing the activity of Co3O4 have been focused on exposing more Co cations on the surface. Herein, we enhance the catalytic activity of Co3O4 by replacing the Co ions in the lattice with Cu. Polycrystallin...
