Supporting Information available onlineThe direct electrochemical synthesis of NH 3 from nitrogen and water vapor without the use of a fossil carbon source is highly desired. This synthesis is a viable option to store energy and produce fertilizer precursors. Here, a new Pt-free membrane electrode assembly is presented. An electrochemical membrane reactor demonstrates the feasibility of co-generating NH 3 and H 2 directly from nitrogen and water vapor at ambient conditions. An unprecedented high NH 3 -specific current efficiency of up to 27.5% using Ti as cathodic catalyst is reported. The co-generation can be tuned by the balance of process parameters.
