Abstract. A set of nanocrystalline cobalt oxide (Co3O4)-based catalysts have been prepared by means of an innovative soft reactive grinding (SRG) procedure. The catalysts exhibited excellent activities and high stabilities for propane catalytic combustion. Complete conversion has been achieved at reaction temperatures as low as 240 ◦C. Comparing with the highly active Co3O4 catalysts in t…
Abstract. A series of gold catalysts deposited on various single-phase manganese oxides (MnOx, including MnO2, Mn2O3 and Mn3O4) were studied in relation to their performance in the low-temperature oxidation of CO. Gold was deposited onto the MnOx support by deposition–precipitation with urea (DP urea). The activity of the Au/MnOx catalysts for CO oxidation strongly depends on the nature o…
