Abstract
Here, we present the first nanoscale chemical imaging study revealing the spatial distribution of the amount and coordination environment of aluminum in zeolite materials with 3D scanning transmission X-ray microscopy (STXM). For this purpose, we have focused on two showcase samples involving the industrially relevant zeolite H-ZSM-5. The first one is a calcined H-ZSM-5 commercial zeolite powder, labeled as ZSM-5-C. The second material with sample name ZSM-5-S has been obtained by steaming ZSM-5-C at 7008C for 3 h. Further details on the preparation and physicochemical properties of both materials can be found in the Supporting Information of a recent article.
