ZSM‐5 at work: Acid‐catalyzed condensation of furfuryl alcohol in the pores of zeolite ZSM‐5 was followed under the fluorescence microscope. During the lifetime of a catalyst, from the reaction start to deactivation, the reactivity of the different crystal segments varies. The technique allows the heterogeneity of activity within individual crystals to be visualized (see picture).
