Different Synthesis Protocols for Co(3)O(4)–CeO(2) Catalysts—Part 1: Influence on the Morphology on the Nanoscale

Co(3)O(4)-modified CeO(2) (Co/Ce 1:4) was prepared by a combination of sol–gel processing and solvothermal treatment. The distribution of Co was controlled by means of the synthesis protocol to yield three different morphologies, namely, Co(3)O(4) nanoparticles located on the surface of CeO(2) parti...

description Co(3)O(4)-modified CeO(2) (Co/Ce 1:4) was prepared by a combination of sol–gel processing and solvothermal treatment. The distribution of Co was controlled by means of the synthesis protocol to yield three different morphologies, namely, Co(3)O(4) nanoparticles located on the surface of CeO(2) particles, coexistent Co(3)O(4) and CeO(2) nanoparticles, or Co oxide structures homogeneously distributed within CeO(2). The effect of the different morphologies on the properties of Co(3)O(4)–CeO(2) was investigated with regard to the crystallite phase(s), particle size, surface area, and catalytic activity for CO oxidation. The material with Co(3)O(4) nanoparticles finely dispersed on the surface of CeO(2) particles had the highest catalytic activity.
