A series of novel Mo modified Mo(x)-MnOx catalysts were prepared by co-precipitation and used for NH3-SCR removal of NOx at low temperatures, which were characterized by XRD, BET, TEM, H2-TPR, NH3-TPD, XPS and in situ DRIFT. It can be found that the addition of Mo species could induce the granular crystals transformed to the oblong-shaped nanorods, then BET surface area was obviously increased. Among...
SAPO-34 crystallites with 160–550nm were synthesized by a two-step hydrothermal crystallization and characterized by XRD, SEM, XRF, low-temperature N 2 adsorption and NH 3 -TPD. The H 2 O 2 aqueous solution was used to remove template. The size effects of SAPO-34 crystallites on its catalytic performance (the catalytic activity, lifetime and coking formation) were investigated...
