Robust dehydrofluorination of HFC-245fa to HFO-1234ze via in situ VOFx formation over a non-oxalic acid assisted V 2 O 5 /γ–Al 2 O 3 catalyst
Source abstract
Abstract
-TPD and XPS analysis. The catalyst also exhibited ∼81% selectivity towards HFO-1234ze(E) at 350 °C. It is noteworthy that the catalyst maintained a stable performance up to 74 h, without significant deactivation. Overall, these results highlight the importance of rational metal selection, loading optimization, and interface engineering in developing robust catalysts for industrial hydrofluoroolefin production.
