In addition, the influence of sulphur on NH3-SCR activity was investigated. The catalysts were characterized by transmission and scanning electron microscopy, energy-dispersive X-ray analysis, and X-ray diffraction techniques. In addition, IR measurements were done to determine the adsorbed species on the catalyst surface. The maximum NO conversions over the catalysts were as high as 85% for Pt/CNT (at 192°C), 54% for Pd/PdO/CNT (at 291°C), and 48% for Rh/CNT (at 292°C) with NH3 as the reducing agent. The SO2 deactivation was the most severe in the case of Pd/PdO/CNTs. In the EtOH assisted SCR the maximum NO conversions were 100% for Pt/CNT, 98% for Pd/PdO/CNT and 85% for Rh/CNT.
