详细技术说明

We have developed a very high-efficiency electrochemical process for generating ammonia, either as a gas or in solution. We have identified a novel family of nanostructured electrocatalysts, which, combined with a novel electrolyte, together provide a very significantly increased efficiency of reaction. Our new electro-catalysts selectively and efficiently catalyse reduction of nitrogen (N2) to ammonia (NH3). These new catalysts overcome the problems associated with previous electrocatalysts that do not have high enough efficiency, catalytic activity and stability for an economically feasible N2 reduction process. In addition, our patented electrolyte medium offers the advantage of elevated solubility for N2 gas, increasing the concentration of nitrogen at the electrolyte / electrode interface, contributing to increased efficiency at ambient temperature and pressure. The system makes use of atmospheric nitrogen or potentially could use nitrogen generated as a product from ammonia fuel cells.
