Activated carbon/graphene composite electrodes with green polymeric binder for carbon dioxide reduction: Preliminary study

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 experiment, CMC an individual polymeric produce least amount weight loss (8.28%). To enhance adhesion, was mixed synthetic (PEI), which results in mass 1.86%. Furthermore, electrochemical analysis depicts that AC/GO-SA produces highest current rate (-7.8 mA/cm-2) throughout 30 min reduction process, 16.9% Faradaic efficiency. The experimental show facile, low-cost, eco-friendly design is promising for carbon dioxide reduction, thus, promote greener technology.
