摘要：Various Er modified MnO_(x) catalysts were synthesized using co-precipitation approach and tested in the selective catalytic reduction of NO_(x) by ammonia(NH_(3)-SCR).Catalysts were analyzed with various characterization techniques,and it is found that the doping of Er can enormously enhance the catalytic performance of MnO_(x)catalyst.MnEr_(0.1)demonstrates advantageous catalytic performance in the NH_(3)-SCR reaction owing to rich surface acidic sites,high surface content of Mn^(4+),superior redox capacity,and enhanced surface-adsorbed oxygen.From diffuse reflectance infrared Fourier transform spectroscopy(DRIFTs)analysis,it is suggested that the MnEr0.1catalyst follows mainly Eley-Rideal mechanism while MnO_(x) is dominated by Langmuir-Hinshelwood mechanism.
