Low-temperature CO oxidation over nanosized Fe–Co mixed oxide catalysts: Effect of calcination temperature and operational conditions

Structure–activity relation of spinel-type Co–Fe oxides for low-temperature CO oxidation

“…This is in excellent agreement with the results reported in the literature for the same material. 30,65 In this investigation, the results demonstrate that the combination of Fe and Co in the same phase intrinsically influences the redox properties and the catalytic performance of Co-Fe-O vs. Fe 2 O 3 in CO oxidation and causes the shift of the optical band gap toward lower values. It is therefore likely that the controlled variation of the Co : Fe ratio in the cobalt ferrite oxides could be used as a tool to reflect their properties.…”

“…Cobalt ferrite spinels have been intensively investigated as catalysts for various reactions. 24,29,30 A single cobalt ferrite with a composition of Co 2.1 Fe 0.9 O 4 (identical with one of the materials discussed in this article) has also recently been used as a catalyst for DME, propene and n-butene oxidation. 31 Because it showed interesting catalytic behaviour against these compounds, it was used in this work to study the influence of the composition in a more systematic fashion.…”

Low-temperature deep oxidation of olefins and DME over cobalt ferrite

“…Co 2+ /Co and Fe 3+ ! Fe 2+ / Fe [19]. Figure 5c and d shows the TPO profile and the recovery of the inverse spinel structure in the re-oxidation process.…”

Catalytic Oxidation of CO over Nanocrystalline La1–xCexNiO3 Perovskite‐Type Oxides

“…Catalytic CO oxidation is an attractive reaction with various industrial applications in CO 2 lasers, proton‐exchange membrane (PEM) fuel cells, catalytic converters, etc. . The precious metals supported on the reducible or irreducible oxides exhibit high activity in this reaction , .…”
