Parallel IR spectroscopic characterization of CO chemisorption on Pt loaded zeolites

FTIR spectroscopy in transmission mode combined with a focal plane array (FPA) detector was employed for parallel characterization of Pt-containing zeolites ZSM-5 and Y. The different Pt species in the zeolite were investigated using the chemisorption of carbon monoxide. With the new transmission setup, 8-fold degree of parallelization was achieved. This significantly lowered the total time required for collection of the desired information from a set of samples. The optical setup based on FPA-IR detection provides data of high reliability. For the discussion of the individual IR band assignment, TEM analysis data are included to corroborate the conclusions.
