Aberration-corrected (AC) STEM, AC TEM and in situ X-ray absorption fine structure spectroscopy (XAFS) were used to characterize the Pt clusters present on a 0.35 wt % Pt on γ-alumina support after reduction in hydrogen at 700 °C. STEM high-angle a

Accumulation of carbonaceous deposits (also known industrially as “coke”) on catalytic active sites derived from process conditions has been a long-standing problem in industrial catalysis. Over accumulation of the deposits ultimately lead to dea

We describe the results of an X-ray absorption spectroscopy (XAS) study of adsorbate and temperature-dependent alterations of the atomic level structure of a prototypical, noble metal hydrogenation and reforming catalyst: ∼1.0 nm Pt clusters suppor
