The Poisoning Effect of Na Doping over Mn-Ce/TiO2 Catalyst for Low-Temperature Selective Catalytic Reduction of NO by NH3
Figure 1
Variations of NO conversion efficiency with temperature for prepared Mn/Ce-TiO2 catalysts. (a) Comparison of catalytic activity over the Na doped Mn-Ce/TiO2 prepared by different Na precursors. (b) Comparison of catalytic activity over Mn-Ce/TiO2 (C) with different Na doping amounts. (c) Comparison of catalytic activity over Mn-Ce/TiO2 (N) with different Na doping amounts. Operating conditions: 500 ppm NO, 500 ppm NH3, 5% O2, and balance N2, GHSV = 24,000 h−1.
