Perfluorocarbons (PFCs) are synthetic industrial chemicals, which, once released into the atmosphere, exhibit strong greenhouse effects. They also potential products of incomplete degradation per- and polyfluoroalkyl substances in thermal processes. This study aims to fill a significant gap literature regarding stability PFCs. Among PFCs examined, perfluorohept-1-ene (C7F14) perfluorooct-1-ene (C8F16) degraded at temperatures as low 200 °C, achieving near-complete approximately 300 °C. The mineralization these two unsaturated reached up ∼40 mol % between °C 500 In contrast, their saturated counterparts required significantly higher (≥600 °C) for similar levels yielded less than 10 fluorine. disparity is likely due hemolytic cleavage relatively weak C3–C4 bonds PFCs, initiating radical-chain reactions that release analysis indicates pathways perfluoroalkenes predominantly involve chain scission cyclization, leading formation various linear cyclic byproducts, particularly below addition granular activated carbon enhanced whereas common commercial catalysts were only moderately effective or ineffective.
