dc.description.abstractThe design and performance of a new high-pressure and high-temperature cell for measurement of x-ray absorption fine structure (XAFS) spectra of solid catalysts working in a flowing liquid are presented. The cell has flat, high-purity sintered cubic boron nitride (c-BN) windows which can tolerate high temperature (900 K) and high pressure (10 MPa). The c-BN is a new material which has the highest tensile strength, second only to diamond, and is also chemically and thermally stable. The use of the cell is demonstrated for measurements of PtPd/Al(2)O(3) and Ni(2)P/SiO(2) hydrodesulfurization catalysts at reaction conditions. A technique called delta chi (Delta chi), involving determining the difference between XAFS spectra of the sample at reaction conditions and the bare sample, is introduced.
