Abstract MnO x /AISI 304 austenitic stainless‐steel monolithic catalysts were prepared by impregnation with aqueous solutions of manganese nitrate or acetate. The preparation method was satisfactory in terms of reproducibility and adherence of the deposited phase. The use of different precursors led to significantly dissimilar results. With manganese nitrate, the formation of Mn‐Cr‐O mixed phases on the surface was favored, whereas with manganese acetate, Mn 2 O 3 was the predominant active phase. The Mn‐Cr‐O mixed phases would be highly dispersed but their catalytic activity was low. The major catalytic behavior was obtained with monoliths impregnated with manganese acetate.
