(FexNi1−x)4N nanoparticles: magnetism and electrocatalytic properties for the oxygen evolution reaction

“…As an important type of functional material, transition metal nitrides (TMNs) exhibit unique electronic and catalytic properties 1,2 and have widespread application in the fields of energy storage and conversion, [3][4][5][6] microwave absorption, 7,8 industrial catalysis [9][10][11][12] and so on. Compared with cobalt-based or Ni-based nitrides, iron nitrides such as x-Fe 2 N, e-Fe 3 N, g 0 -Fe 4 N, a 00 -Fe 16 N 2 , and so on, are attracting much more attention because of their various crystal structures, abundant resources and excellent magnetic properties.…”

“…[13][14][15] In particular, g 0 -Fe 4 N has become a research hotspot in the fields of spintronic devices and magnetic energy storage due to its advantages of a high saturation magnetization (208 emu g À1 ) which is close to that of a-Fe (218 emu g À1 ), and its unique crystal structure which is similar to that of anti-perovskite. 3,[16][17][18][19][20] In general, g 0 -Fe 4 N has a facecentered cubic structure, which is equivalent to embedding a nitrogen atom in the center of the octahedron of the face-centered cubic g-Fe, which endows it with metal-like properties. 14,21,22 In addition, g 0 -Fe 4 N has attracted increasing attention in the field of electrochemical catalysis due to its special metal-like properties, and many composites associated with g 0 -Fe 4 N have been found to be efficient catalysts for the oxygen evolution reaction (OER) and oxygen reduction reaction (ORR).…”
