“…Catalytic oxidation of carbon monoxide is of great importance in a variety of practical applications, such as automobile exhaust purifiers, CO gas masks and CO sensors 1 . McKinney first reported transition metal oxides as catalysts for oxidation of CO 2 . Since then, noble metals, especially Pt, Pd and Au, are widely employed for catalytic oxidation of CO 3 .…”

Catalytic oxidation of carbon monoxide (CO) is of great importance in many different fields of industry. Until now it still remains challenging to use non-noble metal based catalysts to oxidize CO at low temperature. Herein, we report a new class of nanoporous, uniform, and transition metal-doped cerium (IV) oxide (ceria, CeO2) microsphere for CO oxidation catalysis. The porous and uniform microsphere is generated by sacrificed polymer template. Transition-metals, like Cu, Co, Ni, Mn and Fe, were doped into CeO2 microspheres. The combination of hierarchical structure and metal doping afford superior catalytic activities of the doped ceria microspheres, which could pave a new way to advanced non-precious metal based catalysts for CO oxidation.

“…The oxygen vacancy concentration of 3CuO/α-MnO 2 -200-DP was the highest. According to previous reports [38], the formation of oxygen anion radicals was due to the increased adsorption of environmental oxygen by surface oxygen vacancies, which will further improve the performance of catalysts. Figure 6 shows the XPS spectra of Mn 2p, O 1s and Cu 2p in xCuO/α-MnO 2 -200-DP catalysts with different CuO loadings.…”

A series of CuO-based catalysts supported on the α-MnO2 nanowire were facilely synthesized and employed as the CO oxidation catalysts. The achieved catalysts were systematically characterized by XRD, SEM, EDS-mapping, XPS and H2-TPR. The catalytic performances toward CO oxidation had been carefully evaluated over these CuO-based catalysts. The effects of different loading methods, calcination temperatures and CuO loading on the low temperature catalytic activity of the catalyst were investigated and compared with the traditional commercial MnO2 catalyst with a block structure. It was found that the slenderness ratio of a CuO/α-MnO2 nanowire catalyst decreases with the increase in CuO loading capacity. The results showed that when CuO loading was 3 wt%, calcination temperature was 200 °C and the catalyst that was supported by the deposition precipitation method had the highest catalytic activity. Besides, the α-MnO2 nanowire-supported catalysts with excellent redox properties displayed much better catalytic performances than the commercial MnO2-supported catalyst. In conclusion, the CuO-based catalysts that are supported by α-MnO2 nanowires are considered as a series of promising CO oxidation catalysts.

“…1 The oxidative removal of toxic CO became a necessity in pollution control with the development of petrochemical industry during World War I and then the investigations to oxidize CO at room or lower temperatures were carried out. 2 The oxidation of CO into CO 2 on copper oxide in 1878 represented the earliest research in this field, 3 to the best of our knowledge, and then noble metal (NM) catalysts were developed 2,4 and are still being actively used because of their extraordinary activity. A lot of research efforts has been devoted to elucidating the mechanisms of CO oxidation over NM catalysts and the important Langmuir− Hinshelwood kinetics 5 was identified unambiguously.…”

Oxidation of CO into CO 2 is a prototypical reaction in heterogeneous catalysis and is one of the extensively studied reactions in the gas phase to explore the underlying mechanisms of related catalysis. In this Feature Article, we present and discuss our recent advances in the fundamental understanding of catalytic CO oxidation by O 2 mediated with heteronuclear metal oxide clusters (HMOCs) using state-of-the-art mass spectrometry and quantum chemistry calculations. The HMOCs can be considered as ideal models for active sites on mixed or oxide supported catalysts at a strictly molecular level. A concept of electronegativity-ladder effect was proposed to account for the enhanced reactivity of noble metal (NM) doped HMOCs, and then this effect was successfully extended in the design of NM-free HMOCs in catalytic CO oxidation by O 2 . The future directions and the challenges were also discussed.
