Which side are you on? Scanning transmission X‐ray microscopy is used for the first time to elucidate the coordination and distribution of aluminum in industrial‐relevant zeolites at the single‐particle level. Extended regions of a few hundred nanometers, rich in higher aluminum coordination environments, are heterogeneously embedded within the zeolite particle, before and after a steaming post‐treatment.
