Improvement on the Catalytic Performance of MoO3 Nanobelts for NH3-SCR Reaction by SnO2-Modification: Enhancement of Acidity and Redox Property

Enhancing effect of Cu and Sn doping on low-temperature catalytic activity and operating temperature window of γ-Fe2O3 in NH3-SCR of NOx

“…Concerning Cu/g-Fe, 4+ to Sn 2+ together result in a peak at 324 1C. [38][39][40] Moreover, the H 2 consumption of different catalysts is determined by calculating the peak area and listed in Table 3. The total H 2 consumption of these catalysts follows Cu/g-Fe 4 Sn/g-Fe 4 g-Fe 2 O 3 , agreeing well with the catalysts' activity.…”

“…36,37 Regarding Sn/γ-Fe, the peaks at 235 and 279 °C are attributed to the reduction of surface and sub-surface Fe 2 O 3 to Fe 3 O 4 , whereas the bulk Fe 2 O 3 to Fe 3 O 4 and part of the surface Sn 4+ to Sn 2+ together result in a peak at 324 °C. 38–40 Moreover, the H 2 consumption of different catalysts is determined by calculating the peak area and listed in Table 3. The total H 2 consumption of these catalysts follows Cu/γ-Fe > Sn/γ-Fe > γ-Fe 2 O 3 , agreeing well with the catalysts’ activity.…”
