Abstract
We demonstrate second and sub-second time resolved energy dispersive EXAFS (EDE) for in situ interrogation of phase changes in a supported metal catal yst precursor [(less than or equal to 5 wt%) Pt(acac)(2)/H-I SiO2] during t hermal decomposition and reduction; the formation of Pt particles is radica lly altered by the presence H-2, in both kinetic and structural senses.
