Here we propose a new strategy in which two isomorphic metal organic frameworks (MOFs) [FJU-40-H (a) and FJU-40-NH2 (b)] are used to construct the core-shell material MOF@-MOF. This strategy based on nitrogen doping and specific surface has resulted in an N-doped porous carbon (NPC) material in a one-step thermal treatment in N2 atmosphere; this material displays high catalytic activity for the oxygen reduction reaction (ORR). The materials were analyzed by SEM, XPS, Raman, specific surface area, pore size distribution and electro chemical measurements. It was found that NPC derived from.the core-shell MOF@MOF can provide excellent catalytic ORR performance exceeding that of the single MOF. The onset potential is NPC-b@a-4h ( 0.068 V)>NPC-a@b-4h ( 0.075 V)>NPC-a-4h ( 0.109 V)>NPC-b-4h ( 0.113 V). Moreover, the results also show that the performance of NPC-b@a (n=4.15) is.better than that of NPC-a@b (n=3.32), which means the different nitrogen content of ligands inside and outside of the core affects the ORR properties.
