Electrocatalytic hydrogen cycle with oxygen, carbon and nitrogen resources is of emerging interest for renewable energy and environment. ELEE focuses on developing efficient and high-performing electrocatalysis system for oxygen, carbon and nitrogen mediated hydrogen cycle via 1) designing reactive and selective electrocatalysts and electrolytes, 2) fabricating atomic- to large-scale electrode and system, and 3) developing on-line analytical techniques to identify reaction intermediates and products.
