Hydrogen Electrooxidation in Ionic Liquids Catalyzed by the NTf₂ Radical.

ABSTRACT: Hydrogen electrooxidation via a "hydrogen abstraction" mechanism in an aprotic ionic liquid 1-butyl-1-methylpyrrolidinium bis-(trifluoromethylsulfonyl) [Bmpy][NTf₂] under anaerobic conditions was investigated using cyclic voltammetry and density functional theory (DFT). It is found that a platinum bound NTf₂ radical (NTf₂^•) formed by the oxidation of NTf₂^- at anodic potential can catalyze the oxidation of hydrogen and enhance its reaction rate. Both experimental and theoretical studies (DFT) have supported a mechanism involving a NTf₂^• radical intermediate that catalyzes the hydrogen redox processes.
