摘要： The invention provides a cathode for the nitrogen reduction reaction, comprising an electrically conductive substrate and an electrocatalytic composition on the substrate, wherein the electrocatalytic composition comprises: a support material present in one or more crystalline phases; and metallic clusters dispersed on the support material, the metallic clusters comprising at least one metal selected from ruthenium, iron, rhodium, iridium and molybdenum, wherein at least 80 mass % of the support material is present in a semiconductive crystalline phase having a conduction band minimum energy below (more positive than) −0.3 V relative to the normal hydrogen electrode (NHE).
