The Haber-Bosch process for NH3 synthesis is extremely energy intensive requiring a temperature of around 500 oC and a pressure reaching up to 300 atm. Therefore, the development of an alternative, sustainable, efficient, and a selective approach for reducing N2 to NH3 is of great importance. The current work explores the electrochemical route for reducing N2 to NH3 close to ambient conditions using an alkaline electrolyte. A major challenge for following this route is the development of an efficient electrocatalyst and effective electrochemical cell to yield a higher Faradaic efficiency for NH3 synthesis as the N2 reduction reaction (N2RR) competes with the hydrogen evolution reaction (HER) in the aqueous medium. Here we report the use of a carbon-supported Cu as the electrocatalyst for N2RR. The catalyst is synthesized by electrodepositing Cu from a copper (II) nitrate solution on a porous carbon paper and characterized by SEM, XRD, and XPS. We designed and fabricated a compact electrochemical cell to perform the electrochemical studies. The electrochemical cell accommodates a gas diffusion electrode (GDE) that acts as an interface between the continuously recycled aqueous electrolyte on one side and the constantly fed N2 gas on the other. The product distribution is determined by the in-situ GC analysis to monitor the HER and NH3 formation is measured by UV-Vis absorbance spectra of Nessler’s Reagent sparged with product gases. The effects of different operating parameters such as pH, temperature, catalyst loading, and gas and liquid flow rates are studied to determine the optimum operating conditions and kinetics of N2RR.
