Abstract

Sulfur hexafluoride (SF6) is widely used as an insulating medium in electrical equipment but is a potent greenhouse gas with a high global warming potential (GWP). γ‐Al2O3 is a common catalyst for degrading perfluorinated compounds (PFCs), but its performance declines due to fluoride formation during prolonged reactions. This study investigates a new AlPO4/γ‐Al2O3 catalyst for SF6 degradation. By modifying γ‐Al2O3 with phosphoric acid via impregnation, the catalyst's activity and stability were significantly enhanced. The optimal mass ratio of phosphoric acid to γ‐Al2O3 was found to be 20%. The effects of initial gas concentration, catalyst dosage, and gas flow rate on catalyst performance were also examined, offering valuable insights for industrial SF6 catalytic degradation applications.
