英文摘要	A "Spontaneous bubble-template" method is fascinating in that bubbles are formed in situ during material processing and employed as a template for fabricating unique structures, which has not been reported in material science. It is sustainable, green and efficient in that no extra additives or post-treatment are used. Herein, novel metal-polymeric framework derived hierarchically porous carbon/Fe3O4 nanohybrids are prepared using a "spontaneous bubble-template" method by one-step carbonization. During the carbonization process, N and Co are self-doped on porous carbon in which in situ grown nano Fe3O4 is embedded (Fe3O4@N/Co-C). The as-prepared Fe3O4@N/Co-C displays a three-dimensional interpenetrating morphology (electrochemical active area: 729.89 m(2) g(-1)) with well-distributed Fe3O4 nanoparticles (20-50 nm) which are coated with a carbon layer (3-5 nm). Fe3O4@N/Co-C exhibits remarkable oxygen reduction activity in biofuel cells with a distinct output voltage (576 mV) and power density (918 mW m(-2)), which are 3.6% and 17.8% higher than those of Pt (0.5 mg cm(-2)), respectively. Besides biofuel cells, Fe3O4@N/Co-C may also have the potential for application in chemical fuel cells, since it demonstrates better oxygen reduction activity in electrochemical measurements. Thus, with the virtues of its low-cost, facile synthesis and large-scale preparation, Fe3O4@N/Co-C is a promising electrocatalyst for the oxygen reduction reaction and application in biofuel cells.
