Selective CO oxidation over ceria supported CuO catalysts

Hydrothermally synthesized CuxO as a catalyst for CO oxidation

“…However, unsupported copper oxides have not been commonly used compared to cobalt oxide, 1 while there have been numerous studies on supported copper oxides as catalysts for CO oxidation. 1,[7][8][9]11,17 This is partly due to the issues with stability and the variation in the oxidation state of copper. 1 However, the preparation of supported copper oxides is typically more complex, and thus a simple preparation of highly active and stable unsupported copper oxide catalysts is of signicant interest.…”

Comparative study for low temperature water-gas shift reaction on Pt/ceria catalysts: Role of different ceria supports

“…Many syntheses have been proposed for ceria including flame spray pyrolysis [39][40], incipient wetness impregnation [41][42], co-precipitation [43][44], sol-gel [45][46], hydrothermal [47][48] and micro-emulsion [49][50]. The recent discovery of University of Connecticut mesoporous materials (UCT-1-UCT-53) by Poyraz et.…”

Pt/Fe co-loaded mesoporous zeolite beta for CO oxidation with high catalytic activity and water resistance

“…1 The catalytic oxidation of CO is generally considered as the most efficient way to eliminate carbon monoxide from the environment. Recently, large numbers of catalysts have been developed for CO oxidation, such as metal oxides MnO 2 , 2-4 CuO 5,6 and Fe 2 O 3 , 7 perovskite oxide La 0.5 Sr 0.5 MnO 3 , 8 and precious metal-based catalysts. Generally, non-noble metalbased catalysts can promote the oxidation of CO by the synergetic effect of the different active components, but the complete conversion temperature of CO is generally higher than 150 C. Especially, the catalytic activity of non-noble metal-based catalysts drops substantially under harsh conditions.…”
