Abstract: In the present study, a few types of green polymer binder such as Xanthan gum (XG), Carboxyl methylcellulose (CMC) and Sodium alginate (SA) have been prepared with activated carbon-graphene oxide composite electrode (AC/GO). Throughout the experiment, CMC as an individual polymeric binder produce the least amount of the weight loss (8.28%). To enhance the adhesion, the binder was mixed with synthetic binder (PEI), which results in mass loss of 1.86%. Furthermore, the electrochemical analysis depicts that AC/GO-SA produces the highest current rate (-7.8 mA/cm-2) throughout the 30 min of reduction process, with 16.9% Faradaic efficiency. The experimental results show that a facile, low-cost, eco-friendly design of green polymer binder is promising for the carbon dioxide reduction, thus, promote a greener technology.
