Abstract
The present invention relates to an electrochemical cell based on an aqueous Zn∥NOsystem with a nano-NiO catalyst deposited as gas diffusion cathode, a metallic Zn foil as anode and a ZnClaqueous solution as electrolyte. Importantly, the electrolyte can efficiently capture NO, then convert it to NOand eventually to the value-added NH, while simultaneously producing electric power. The obtained electrochemical cell exhibits bifunctional activity and stability (>100 h) towards reversible NOreduction and evolution reactions. A high cell-level energy density of 553.2 Wh·kg/1589.6 Wh·Lfrom pouch cells (2.4 Ah) has been achieved. As an additional green feature, the produced NOby the Zn∥NOcell is subsequently converted to NHby a self-power mechanism, thereby servicing multiple key conversion steps in the nitrogen cycle all within a single device, paving the way to scalable, highly integrated solutions.
