  Article:   ELECTROREDUCTION OF CARBON DIOXIDE TO FORMATE ON BRONZE ELECTRODE.

Authors:  MARIA JITARU, MARIANA TOMA.
 
       
         
  Abstract:  
This paper presents our data on the electrochemical reduction of carbon dioxide, on bronze electrode (Sn85Cu15) in aqueous medium (0.2 M K2CO3), under CO2 atmosphere, (12-25)0C. The current efficiency for main product (formate) depends on the current density and was found to be up to 74% at high negative potential (> - 1.6 V/SCE), decreasing with operating time and with temperature increase (72-74% at 12 0C and 60-65% at 25 0C).
