Investigation of alcohols oxidation on silver as an electro-catalyst in alkaline solution by electrochemical method

In this research, oxidation of different alcohols (methanol, ethanol, 1-propanol, 2-propanol, ethylene glycol, glycerol, 1-bothanol and 2-bothanol) was studied in alkaline medium on silver catalyst surface by cyclic voltammetry method. The results show that some of the alcohols in the presence of alkaline solution exhibit excess oxidation on silver electro-catalysts, as evidenced by their higher peak current densities, lower onset potentials and better anti-poisoning properties which originated from the tailored geometric and electronic structures of silver.
