摘要：
Herein, an extremely simple l-alanine-assisted pyrolysis method was proposed for the construction of a novel hierarchically porous hybrid of Fe(4)N-Fe supported on N-doped carbon nanobelts and Ketjen black carbon (denoted as Fe(4)N-Fe@N-C/N-KB). It has been found that the participation of l-alanine in pyrolysis can dramatically increase the total pyridinic-N/graphitic-N content in Fe(4)N-Fe@N-C/N-KB, which is peculiarly conducive to the enhancement of ORR performance. The in-site formation of the Fe(4)N-Fe heterojunction via the thermal reduction and decomposition of Fe(3)N as well as the intr...
