摘要： An aerobic method for oxidizing an alkane is disclosed herein. At least a portion of a surface of a platinum working electrode is activated at an interface between the platinum working electrode and an ionic liquid electrolyte (i.e., 1-ethyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, 1-propyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, 1-pentyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, 1-hexyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, 1-heptyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, 1-octyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, 1-nonyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, and 1-decyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imidem, and combinations thereof). An interface complex is formed at the interface. An alkane gas is supplied to the interface. The alkane adsorbs at or near the interface complex. The alkane gas in the presence of oxygen is supplied to the interface. While the alkane gas in the presence of oxygen is supplied to the interface, a positive electrode potential is applied to the platinum working electrode, which causes a reactive oxygen species formed at the interface to catalyze oxidation of the adsorbed alkane to form a reaction product.
