Experimental studies were done in aqueous solutions of sodium and potassium based electrolytes using a cathode [Zinc (Zn) and Tin (Sn)] and a common cobalt oxide (Co3O4) anode electrocatalyst. The influence of reaction with electrolyte concentration for the both catalysts was shown clearly with respect to time. The selected electrocatalysts were able to reduce CO2 to formic acid (HCOOH) along with high BG dye removal. With Sn as cathode, the maximum BG dye removal was obtained...
