    Samenvatting

    Band target Entropy Minimization (BTEM) was applied for the analysis of the DRIFTS data measured during CO and NO reaction over Pt/gamma-Al2O3 catalyst. Some of the vibrational modes of the species not observable in the experimental spectra were only discernable after BTEM analysis. Unlike other self curve resolution techniques, BTEM used no spectral libraries and no a priori information for the pure component spectral recovery. Although the BTEM algorithm has been used repeatedly and successfully for infrared and Raman studies of homogeneous catalytic systems, this is the first time that it has been applied to DRIFTS data from a heterogeneous catalytic system. This is an abstract of a paper presented at the AIChE Annual Meeting (Salt Lake, UT 11/4-9/2007).
