Fe–N–C single-atom catalysts with an axial structure prepared by a new design and synthesis method for ORR
Abstract
FePc powder sublimates losing H atoms to form unstable fragments at 450 °C which self-assemble to form units with a double-layer structure. The self-assembly units are driven by argon gas at 70 °C to where the substrate is located and crystallize to form Fe-N5/C@G catalyst.
