27Al 3Q MAS NMR and UV/Vis spectroscopy with bare CoII ions as probes of Al pairs in the zeolite framework were employed to analyze the location of framework Al atoms in the channel system of zeolite ZSM‐5. Furthermore, the effect of Na+ ions together with tetrapropylammonium cation (TPA+) in the ZSM‐5 synthesis gel on the location of Al in the channel system was investigated. Zeolites prepared using...
