In Situ Generated Platinum Catalyst for Methanol Oxidation via Electrochemical Oxidation of Bis(trifluoromethylsulfonyl)imide Anion in Ionic Liquids at Anaerobic Condition.

ABSTRACT: The bis(trifluoromethylsulfonyl)imide anion is widely used as an ionic liquid anion due to its electrochemical stability and wide electrochemical potential window at aerobic conditions. Here we report an innovative strategy by directly oxidizing bis(trifluoromethylsulfonyl)imide anion to form a radical electrocatalyst on platinum electrode at anaerobic condition. The in situ generated radical catalyst was shown to catalytically and selectively promote the electrooxidation of methanol to form methoxyl radical, in which the formation potential was drastically decreased with the existence of bis(trifluoromethylsulfonyl)imide radical. The electrochemically generated radical catalyst not only facilitates the oxidation of methanol but also provides good selectivity. The unique double layer struc
