摘  要: 使用廉价的日常废棉纺织物作为原材料,通过碳化处理制备了一种新颖的、生物相容性的、多孔的、高导电性的、低成本的碳化棉织物(CCTs)电极,并且用于微生物燃料电池(MFCs)的阳极材料.采用场发射扫描电子显微镜(FESEM),X射线衍射(XRD),拉曼光谱(Raman),傅里叶变换红外光谱(FTIR),X射线光电子能谱(XPS)和BrunauerEmmett-Teller(BET)等方法进行表征.表征结果显示,CCT-1000电极的表面比较粗糙,比表面积为209.64 m^2·g^(–1),大大增强了电极与细菌之间的相互作用,从而增加了细菌在电极上的负载量,促进了细菌胞外电子传递(EET).使用CCT-1000阳极的MFC的输出功率为738±20 m W·m^(–2),比使用商业碳毡阳极的MFC的输出功率提高了43%.另外充分利用廉价的废棉纺织物,可以大大降低MFCs的成本,同时减少环境污染问题. A new biocompatible, porous, high conductive and low-cost electrode, carbonized waste cotton textiles(CCTs) was developed as anode electrode materials for membraneless microbial fuel cells(MFCs). The CCTs are characterized by using Field emission scanning electron microscopy(FESEM), X-ray diffraction(XRD), Raman spectroscopy, Fourier transform infrared spectrum(FTIR), X-ray photoelectron spectroscopy(XPS) and BrunauerEmmett-Teller(BET) method. The results show that the CCT-1000 electrode provides a low electrical resistivity(7.56 Ω·sq^(–1)) and a large surface area(209.64 m^2·g^–1) for bacterial growth, hence greatly increasing the loading amount of bacterial cells and facilitating the extracellar electron transfer(EET). The MFC using the CCT-1000 anode delivers a power output of 738±20 m W·m^2, which is 43% higher than that of commercial carbon felt anode with the same configuration and non-catalyst modification. Moreover, making full use of the cheap electrode and membraneless configuration can greatly reduce cost of MFCs.
