Abstract

original image

Aluminiumoxid im Fluss: Auf Informationen aus Synchrotron-Röntgenpulverbeugungs(PXRD)-Messungen in situ, die einen Reaktionsmechanismus ohne kristalline Intermediate nahelegen, baut die erste einstufige und schnelle Synthese von γ-Al2O3 im Großmaßstab auf. Das γ-Al2O3 wurde bei niedriger Temperatur in einem kontinuierlichen Flussreaktor aus Aluminiumisopropoxid in 2-Propanol/Wasser ohne anschließende Kalzinierung erhalten.
