Formamide Electrosynthesis from Methanol and Ammonia in Water over Pr-Doped MnO.

A rare earth element doping strategy is reported to boost the activity and enhance the stability of MnO for selective formamide production through electrocatalytic oxidation coupling (EOC) of methanol and ammonia. MnO doped with 1% Pr was selected as the best candidate with an optimized formamide yield of 211.32 μmol cm h, a Faradaic efficiency of 22.
