The teams of LIU Jian at CAS DICP and LIANG Kun at the Institute of Superconducting and Electronic Materials, University of Wollongong, Australia, have tried defect engineered iron doping for electrocatalytic nitrogen fixation. Using an iron-doped Wolfram18049 catalyst in a nanoreactor, they achieved 24.7 μg / (h * mgcat) yields of NH3 and 20.0% Faraday efficiency at ambient temperature.
