A comparative study of and catalysts for the catalytic oxidation of CO in hydrogen rich stream

Could an efficient WGS catalyst be useful in the CO-PrOx reaction?

“…The negative effect of CO 2 and H 2 O seems to be cumulative. The decrease in both activity and selectivity of the PrOx catalysts, due to the competitive adsorption of CO, CO 2 and H 2 O on the catalyst surface has been broadly reported [33][34][35][36]. Again a decrease on the O 2 activation rate due to the competition of oxygen with water and carbon dioxide should be considered.…”

Low Temperature Oxidation of Carbon Monoxide over Mesoporous Au-Fe2O3Catalysts

“…It was reported that -Fe 2 O 3 possessed an advantage in that it has a long lifetime because it could resist poisoning from CO 2 [8]. Many research groups [9][10][11][12][13] utilized Au supported iron oxide materials as a catalyst for CO oxidation. However, the controlled synthesis of Au metal oxide nanocomposites still faces tremendous challenges [14].…”

Carbon Monoxide Oxidation Catalysed by Exotemplated Manganese Oxides

“…To the best of our knowledge, this is the first report so far on gold loading into exotemplated manganese oxide supports. In fact the Au/Mn x O y combination itself is not very common in the literature [9][10][11][12][13][14][15][16][17][18][19][20][21], when compared with the extensive work carried out in other supports, such as TiO 2 and CeO 2 (see reviews [22,23]). Also not much has been reported on MnO x catalysts, either pure [24][25][26][27] or with Au [9-11, 13, 14, 16-18, 20, 21] for CO oxidation.…”
