Surface-enhanced Raman scattering technique for comprehensive group-based structural identification of coke deposits on deactivated zeolite catalysts

Abstract

A coke detection strategy based on iodide-modified Ag NPs was established coupled with the release and dispersion of coke species. This method can selectively acquire group-based structural characteristics of coke species deposited on industrially deactivated zeolite catalysts with strong fluorescence within complex systems.
