摘要

以聚苯胺和硝酸盐为前驱体，采用热处理法制备了M-N-C（M=Fe，Co）材料，并将其作为厌氧流化床微生物燃料电池（AFBMFC）阴极催化剂。通过X射线衍射（XRD）、红外光谱（FTIR）、扫描电子显微镜（SEM）对催化剂进行晶型结构和表面形貌的表征。采用循环伏安法（CV）对催化剂的电化学性能进行考察，并应用于AFBMFC，考察了其对电池产电性能的影响。结果表明，使用Fe-N-C催化剂的微生物燃料电池稳定运行时，开路电压达到636.0 mV，功率密度达到166.82 mW·m-2，比使用Pt/C催化剂的微生物燃料电池的功率密度提高10%。表明Fe-N-C催化剂用做微生物燃料电池阴极催化剂具有潜在的应用前景。

Abstract

With polyaniline and metal nitrate as precursors

M-N-C (M=Fe

Co) catalysts were synthesized by heat treatment. The performance of the prepared M-N-C catalysts for cathode catalysts of anaerobic fluidized bed microbial fuel cell (AFBMFC) was examined. The prepared catalysts were characterized by X-ray diffraction (XRD)

Fourier transform infrared spectroscopy(FTIR)

and scanning electron microscope (SEM). The electrochemical characteristics were investigated with cyclic voltammetry (CV). Using the catalysts as the cathode catalysts for AFBMFC

the electricity generation performance of the AFBMFC was examined. The maximum power of AFBMFC operating with Fe-N-C cathode catalyst was 166.82 mW·m-2

10% higher than AFBMFC with Pt/C catalyst. The open circuit voltage was up to 636.0 mV. Fe-N-C as a microbial fuel cell cathode catalyst has good activity and broad prospect.
