“…Subsequently, the absorption intensities were divided by the theoretical IR absorption coefficient calculated in section 3.1.1.1. Literature values 98,103,105,106,110,111,[114][115][116]120,121 and our data are in general agreement.…”

Ultrafast high-intensity laser pulses incident upon condensed matter targets can generate high-density plasmas that emit x-ray pulses with sub-picosecond temporal structure, significant spatial coherence, and high brightness at kilohertz repetition rates. Such laser-driven plasma x-ray sources based on solid and liquid metal targets have been developed in our laboratory. Essential performance features are discussed along with a feasibility evaluation for future routine application in chemical research. Laser-driven x-ray sources are usable for ultrafast x-ray diffraction and ultrafast x-ray absorption spectroscopy. X-ray absorption near-edge spectra of solvated transition metal complexes are presented.Ultrafast molecular dynamics depends on the structure of the solvated molecule before photo-excitation. This solvation structure, in turn, depends on the solute's interaction with the solvent molecules. Furthermore, the solute's vibrational modes and its structure are correlated, solvent dependent, and can be measured by mid-infrared and x-ray absorption spectroscopy. Such measured spectra are presented and correlated with quantum calculations in order to elucidate the solvation environment of various transition metal coordination complexes.

“…Similarly, the most prominent infrared bands related to Fe(CO) 5 (ν 2 at 2030 cm -1 , ν 6 at 2002 cm -1 , and ν 10 at 1939-1982 cm -1 ; Bigorgne, 1970;Cataliotti et al, 1971) are not observed here or by prior workers (Wetzel et al, 2013;Stanley et al, 2014), nor are the most prominent Raman bands (ν 2 and ν 10 at the same positions as in the infrared; Bigorgne, 1970;Cataliotti et al, 1971). …”

“…This band was also observed at Pt-Fe(2:1)/M, although the amount of CO adsorbed on Pt sites reduced, especially at 200°C. Fe(CO) 5 vapor gives two infrared bands at 2034 and 2012 cm )1 [18] and IR bands of CO adsorbed on Fe film deposited on Cu(111) appear at 2032 and 2000 cm )1 [19]. At PtFe(2:1)/M, no noticeable bands, which should be assigned to such a CO-Fe bonding, can be observed in figure 5.…”

XAFS Characterization of Pt–Fe/zeolite Catalysts for Preferential Oxidation of CO in Hydrogen Fuel Gases

et al. 2005

We have developed a new Pt-Fe/mordenite (Pt-Fe/M) catalyst which shows remarkably high activity and selectivity for the oxidation of CO in H 2 -rich gas compared with Pt/M. In the present work, to understand the role and structure of Pt and Fe in the Pt-Fe/M catalyst, the states of metallic components in ion-exchanged, H 2 pre-treated and post-PROX (preferential oxidation of CO) samples have been studied by means of XAFS. It was confirmed that Pt forms the metallic clusters after H 2 pretreatment or the PROX experiment, whereas a large part of Fe exists as oxides even after the H 2 treatment. At post-analysis of the catalysts used for the PROX experiment, an increase in coordination number of Fe-O was observed. Pt clusters in the Pt-Fe(2:1 weight ratio)/M catalyst, which showed the highest PROX performance, were found to have a different electronic structure from the other catalysts. Additionally, preferential CO adsorption onto Pt sites at Pt-Fe/M was clearly demonstrated by infrared spectroscopy analysis in a stream of 1% CO containing H 2 . Based on these results, the superior PROX mechanism was discussed.
