Abstract

Abstract

En 中文
• Ru/C and other supported noble metals catalyze hydrothermal PFAS decomposition. • Identified products include F-, short chain PFAS, and bound organofluorine species. • Catalyst acts by promoting C-C bond cleavages along perfluoroalkyl chain. • Use of catalyst eliminates the need for concentrated alkali amendments.
