Abstruct: Amorphous carbon (a-C) based catalysts having higher oxygen reduction
reaction (ORR) activity and higher stability for ORR were realized by inserting
nitrogen atoms in the valleys of zigzag edges of sp2 cluster surface in
a-C. ORR activity could be controlled by varying sizes and volume density
of sp2 cluster. The maximum number of electrons of 2.82 for ORR was achieved.
The N-doped a-C catalysts have the activity of 4-electron O2 reduction
reaction. The catalytic activity was stable in long term (150 times) measurements.
Consequently, the N-doped a-C catalysts possesss ly, imes) measurements
higher stability for ORR.
