Maleic Acid Hydrogenation on Pt in Aqueous Acidic Solutions

3 MALEIC ACID HYDROGENATION ON Pt IN AQUEOUS ACIDIC SOLUTIONS 

Interestingly the electrochemical promotional effect was found only in the case of perchloric acid supporting electrolyte. No promotion effect was found in presence of strongly adsorbed anions (HS04 Cl ). 

This very interesting work is the first demonstration of NEMCA for a hydrogenation reaction in aqueous solutions. It is also the first demonstration of NEMCA in an acidic solution, as all previous electrochemical promotion studies in aqueous media were restricted to alkaline solutions. This work also underlines the importance of the supporting electrolyte and of the strength of adsorption of the anions in aqueous electrochemical promotion studies.
