The activation of CH bonds using an EmimAc/MWCNTs composite: a comparison of the composite used as electrolyte and electrode in aqueous media

An EmimAc/MWCNTs composite was prepared and characterized through SEM and TEM . The MWCNTs were well dispersed after combining with alkaline EmimAc . The activity of the composite was demonstrated by CV and controlled potential electrolysis. The composite could be used independently as electrolyte or electrode and showed excellent activity toward the electro-oxidation of the C H bond of benzylic systems, and did so at a lower oxidation potential than when using EmimAc or MWCNTs . After modification, the pH value of the composite was adjusted to the acid range, and the yield of aldehyde adducts obtained through electro-oxidation improved.
