Description

γ-Al2O3 with 3/4 sphere and cabbage-like structures were prepared via hydrothermal synthesis. Then they were evaluated as catalysts for the dismutation of HCFC-22 as a model reaction for Cl/F exchange reactions with a commercial γ-Al2O3. The results indicate that both hydrothermal samples are formed by the loose assembly of nano-sheets. For cabbage-like alumina, hollow structure is detected. Aluminum chlorofluoride (ACF) structure with strong Lewis acidity is beneficial for dismutation of HCFC-22. Following pre-fluorination by HCFC-22, the high activity of cabbage-like γ-Al2O3 is attributed to the high content of ACF. It indicates that cabbage-like structure tends to form more ACF structure.
