Abstract The degradation of fluorinated refrigerants, known for their highly stable carbon‐fluorine (C─F) bonds, poses significant environmental and technical challenges. This review addresses these challenges by analyzing two core mechanisms: molecular polarization (MP) free radical attack (FRA), exploring applications in thermal catalytic photocatalytic processes. MP redistributes electron density to weaken C─F facilitating adsorption bond cleavage, while involves reactive species that directly break chemical bonds. However, both mechanisms have limitations: alone may lack the kinetic drive dissociation, radical‐based methods often suffer from low selectivity, short lifetimes, formation toxic intermediates. section on discusses how elevated temperatures enhance cleavage through MP, addressing accelerating dissociation. part focuses role light‐activated processes generating radicals breaking, with an emphasis visible ultraviolet light‐driven reactions. concludes potential hybrid systems combine processes, providing insights into complementary use persistent compounds.
