Electrochemical Synthesis of Green Ammonia: Prospects and Challenges
Owing to the rapid depletion of non-renewable energy sources, worldwide research is inclined towards the development of alternative approaches with a long-term vision of a sustainable society. In this advent, green hydrogen/green ammonia plays a dominating role towards a safe, reliable and electrified future. Although to meet the practical demands of ammonia, the Haber–Bosch process is the sole option, it deviates from the goal of a “netzero” society. This calls for the electrochemical approach and we have thus keenly focused to develop versatile materials to achieve significant ammonia production using nitrogen reduction reaction (NRR). We have also developed a full NRR electrolyzer on a laboratory scale with state-of-the-art catalysts and opened up an avenue of how energy consumption could be minimized that in turn brings about a better energy-efficient ammonia synthesis. The fundamental relationships between electronic structure, adsorption energy, and apparent activity towards NRR with the goal of providing a better understanding of these emerging research directions will be described.
