Fig. 6: Effect of Mn content on catalytic performance.
From: Unraveling the structure and role of Mn and Ce for NOx reduction in application-relevant catalysts

Surface-specific activities for the NO reduction at 150 °C plotted as a function of the Mn content on the catalysts. The blue dots correspond to the ternary MnCeTi catalysts. The red dots are from the binary MnTi and the individual Mn catalysts. Red and blue trendlines were added to guide the eyes.
