Catalytic Decomposition of Perfluorinated Compounds

Perfluorinated compounds (PFCs) are a class of synthetic chemicals in which all hydrogen atoms are replaced by fluorine, imparting exceptional chemical and thermal stability. Their remarkable resistance to natural degradation leads to persistent environmental accumulation and high global warming potential. The catalytic decomposition of PFCs seeks to overcome the inherent strength of carbon–fluorine bonds by employing tailored catalysts that lower activation barriers and direct reaction pathways toward manageable end-products such as carbon dioxide and hydrogen fluoride. Techniques span catalytic hydrolysis, oxidative and reductive routes, often conducted under controlled temperatures to balance energy input and conversion efficiency. Advances in catalyst architecture and surface chemistry have yielded materials capable of sustained activity, selectivity and resistance to fluorine poisoning, supporting applications in industrial emissions control, semiconductor manufacturing off-gas treatment and remediation of contaminated water and soil.
