Structure-Activity relationship in HC-SCR of NO2 by TEM, O2-chemisorption, and EDXS study of Ag/Al2O3

The difference in mean particle sizes (MPS), particle size distribution and dispersion for four fresh Ag/Al2O3 catalysts with different metal loadings were determined by means of HRTEM, high angle annular dark field (HAADF), O2-chemisorption and X-ray energy dispersive spectroscopy (EDXS). The MPS values determined by HRTEM resulted in increasing MPS value with increasing metal loading as expected.
