摘要
The high efficiency of cathode catalyst used in the oxygen reduction reaction is a vital factor guaranteeing for the microbial fuel cells (MFCs). In this work, two novel nickel cobaltite@nanocarbon hybrids were rationally designed and successfully prepared as efficient cathode catalysts in air-cathode MFCs. Impressively, the achieved maximum power density of the MFCs equipped with NiCo2O4@MWCNTs cathode was about 356 mW m(-2), which is significantly higher than that of the MFCs with other cathodic catalysts. This work may provide not only the fundamental studies on nanocarbon-supported mixed-valent transition-metal oxides but also a new kind of promising alternative electrode in the technology of power generation from MFCs.
