Abstract

A vibrational fingerprint: A Raman technique has been developed to retrieve spatiotemporal chemical information from millimeter-sized catalyst bodies under preparation. An incipient wetness impregnation of γ-Al2O3 catalysts with ammonium heptamolybdate was followed. Diagonal offset Raman spectroscopy was able to distinguish between surface, subsurface, and bulk phase of the catalyst bodies.
