Bases play an important role in the glycine electrooxidation mediated by TEMPO and Ni(OH)2. A trend of 2,4,6-collidine > 2,6-lutidine>3-picoline > pyridine was observed in TEMPO mediated glycine electrooxidation. The catalytic activity of Ni(OH)2 mediated glycine electrooxidation is highest in KOH, followed by NaOH and LiOH. Acid neutralization, base assisted deprotonation and the interaction between bases and catalysts result in base effects.
