there are two inequivalent Fe sites. In the first Fe site, Fe is bonded in a distorted bent 120 degrees geometry to two equivalent C atoms. A series of designed experiments disclosed that (1) N-doped carbon substrate, Fe/Fe3C nanocrystals or Fe–Nx themselves did not deliver the high activity; (2) the catalysts with both Fe/Fe3C nanocrystals and Fe–Nx exhibited the high activity; (3) the higher content of Fe–Nx gave the higher activity; (4) the removal of Fe/Fe3C nanocrystals severely degraded the activity; (5) the blocking of Fe–Nx downgraded the activity and the recovery of the blocked Fe–Nx recovered the activity.

In carbon steel, it either forms from austenite during cooling or from martensite during tempering. When the pyrolysis temperature reaches 600 °C, the as-obtained composite, Fe/Fe 3 C@NCNTs-600 can perform a maximum reflection loss of −46.0 dB at 3.6 GHz with a thickness of 4.97 mm and a qualified bandwidth of 14.8 GHz with the integrated thickness from 1.00 to 5.00 mm.
