In situ FTIR-microspectrometry: spatial differentiation of CO during chemisorption and oxidation on highly orientated graphite-supported Pt
Abstract
FTIR-microscopy has been used in situ to characterise catalyst surfaces; with CO on graphite-supported Pt during chemisorption and oxidation it reveals surface heterogeneity and may suggest that the more reactive bridge-bound CO is predominantly found at the outer edge of CO islands on the surface.
