SnO 2 Promoted by Praseodymia: Novel Catalysts for CO Oxidation

“…Our previous work also demonstrated that Fe, Cr and Mn modified SnO 2 -based solid solution catalysts are very active for CH 4 combustion with high thermal stability and reaction endurance [20][21][22]. However, using praseodymia to modify SnO 2 to prepare catalysts for CO oxidation has been rarely documented, though some material scientists used praseodymia to promote the performance of SnO 2 as gas sensors [24][25][26] or as electrodes [27]. Based on the unique properties of both SnO 2 and praseodymia, we think it could be possible get some promising catalyst formulations for CO oxidation with the combination of the two types of oxides, and deserve to have a try.…”
