| Abstract |
As demand in energy storage increases, it is inevitable to develop more efficient energy conversion/storage systems. Accordingly, low-cost and highly active catalysts for oxygen reduction reaction (ORR) and batteries are of a great interest. Porous carbon nanomaterials are attracting attention as promising substitutes for Pt-based ORR electrocatalysts with outstanding stability, high activity, and high electric conductivity. Furthermore, heteroatom doping is an efficient strategy for improving ORR catalytic activity of porous carbon nanomaterials. However, there are still remains a daunting challenge reduce the cost and complexity of synthetic process for heteroatom doped porous carbon materials. Herein, we describe a reliable and controllable synthesis method for low-cost and convenient preparation of nitrogen, sulfur-codoped porous carbon (NSPC). We synthesized a new metal-organic framework (MOF), S-modified Zn-MOF-74, which is highly porous and contains sulfur atoms dispersed homogeneously within the structure. NSPC synthesized by doping the nitrogen and sulfur precursor, thiourea, to S-modified Zn-MOF-74 showed comparable or even better catalytic performance for ORR compared with commercial Pt/C catalysts. |
