Elucidation of the Roles of Rhenium in Vapor-Phase Reforming of Glycerol over Pt-Re/C Catalyst

Using in situ XAS, Raman, and ATR-IR, we provide better understanding of catalyst surface structures and their correlation with catalytic performances, particularly under hydrothermal environments and using carbon support. Oxidation of rhenium and CO spillover from platinum to oxidized rhenium are unambiguously attributed to the enhanced activity over PtRe/C catalysts.
