Shaping up operando spectroscopy: Raman characterization of a working honeycomb monolith
Abstract
A new monolithic reactor for operando Raman spectroscopy studies of honeycomb-shaped catalysts has been developed to obtain complete information on these systems, considering the effect of conformation on structure–activity relationships; this is illustrated by Raman-GC monitoring of alumina-supported vanadium phosphorous oxide phases during propane ammoxidation with monolithic and powdered beds.
