XAFS characterization of highly active alumina-supported molybdenum phosphide catalysts (MoP/Al2O3)
Article Abstract:
The experiment was conducted where alumina-supported molybdenum phosphide (MoP/Al2O3) catalysts were prepared. The X-ray absorption fine structure (XAFS) analysis indicated the presence of dispersed species retaining metallic bonding with a characteristic Mo-P distance of 0.243nm but showing considerable attenuation in Mo-Mo linkages.

Understanding of enhanced oxygen storage capacity in Ce0.5Zr0.5O2: the presence of an anharmonic pair distribution function in the Zr-O2 subshell as analyzed by XAFS spectroscopy
Article Abstract:
The study was done by standard EXAFS analysis of a Y-doped reference compound and Ce0.5Zr0.5O2 mixed oxides to obtain structural parameters. The results show that the lamellar type structural model explains the high oxygen storage capacity of Ce0.5Zr0.5O2.

The nature of the Pt-H bonding for strongly and weakly bonded hydrogen on platinum. A XAFS spectroscopy study of the Pt-H antibonding shaperesonance and Pt-H EXAFS
Article Abstract:
Pt-H EXAFS in the presence and absence of hydrogen was used to gauge the nature of hydrogen adsorbed on Al(sub 2)O(sub 3) supported Pt-H particles. The Pt-H bond length is longer for weakly adsorbed hydrogen compared to strongly adsorbed hydrogen.
