71Ga, 27Al, and 29Si MAS NMR and DRIFT spectroscopies were used to characterize the state of gallium in Ga/H-ZSM5 catalysts tested for their ability to catalyse the ammoxidation of propane. Ga species were observed in two different possible environme

The state and local environment of gallium species in Ga/H-ZSM-5 zeolites prepared by ion-exchange have been identified by various techniques. Small GaO(OH) particles (diameter ∼4–5 nm) were present after synthesis at the outer surface of the zeo
