Recent advances in degradation of the most potent industrial greenhouse gas sulfur hexafluoride

Computational Insights into Degradation Probability of Small Fluorocarbon Compounds

“…7,8 Furthermore, SF 6 has a long atmospheric lifetime, estimated to be approximately 3200 years, leading to its accumulation in the atmosphere and a potential threat to the Earth's climate system. 3,9 Recognizing these environmental issues, the scientific community and industry stakeholders have been actively exploring alternative insulating gas candidates to mitigate the adverse impacts of SF 6 . 10 Among potential candidates, perfluorocarbon (PFC) compounds have emerged as promising alternative insulating gases to replace SF 6 in various electrical applications primarily owing to the probability of identifying PFC compounds with relatively low GWP.…”

“…Sulfur hexafluoride (SF 6 ) has long been recognized as an exceptional insulating gas due to its unique combination of excellent dielectric properties and thermal stability. − It is widely used in various industries, including electrical power transmission and distribution, as insulation medium for high-voltage equipment such as circuit breakers, switchgear, and transformers. , However, recent research has shed light on the environmentally negative impact of SF 6 , raising concerns about its widespread usage . SF 6 is a potent greenhouse gas with a global warming potential (GWP) thousands of times higher than that of carbon dioxide, contributing significantly to climate change. , Furthermore, SF 6 has a long atmospheric lifetime, estimated to be approximately 3200 years, leading to its accumulation in the atmosphere and a potential threat to the Earth’s climate system. , Recognizing these environmental issues, the scientific community and industry stakeholders have been actively exploring alternative insulating gas candidates to mitigate the adverse impacts of SF 6 …”

Visible-Light-Induced Oxidative Decarboxylative Coupling of Phenylacetic Acid Derivatives Using SF6 as an Oxidant

“…Sulfur hexafluoride (SF 6 ) is a greenhouse gas with high chemical stability, and efficiently degrading or transforming it has long been known as a big challenge . Traditional strategies for SF 6 degradation and activation mainly involve reduction using strong reductants or plasma discharge methods . These approaches often require substantial energy consumption and can produce toxic byproducts.…”
