摘要
本论文采用金属有机框架(MOFs)制备了新型纳米结构多壁碳纳米管(MWCNT)(MWNTs@MOFs-C 碳复合材料)作为高性能生物燃料电池(BFC)的电极载体.分别用黄素腺嘌呤二核苷酸型葡萄糖脱氢酶(FAD-GDH)为生物阳极和漆酶为生物阴极,锇配合物作为电子介体组装了MWNTs@MOFs-C碳复合材料生物燃料电池.得到基于MWNTs@MOFs-C碳复合材料的葡萄糖/O2生物燃料电池较高的最大功率密度 0.51±0.03 mW·cm-2 和开路电压 0.61 V.而生物燃料电池一周后能保持原功率密度的 57%.我们的发现将为以MWNTs@MOFs-C碳复合材料作为电极载体开发更高效的BFC开辟一条途径.
Abstract
In this thesis,a novel nanostructured multi-walled carbon nanotube(MWCNT)composite(MWNTs@MOFs-C carbon composite)was prepared to use metal-organic frameworks(MOFs)as the Electrode Support for high-performance biofuel cells(BFC).The MWNTs@MOFs-C carbon composite-based BFC was assembled with flavin adenine dinucleotide glucose dehydrogenase(FAD-GDH)as the bioanode,laccase as the biocathode,and an osmium complex as the electron mediator.The glucose/O2 biofuel cell based on the MWNTs@MOFs-C carbon composite achieved a high maximum power density of 0.51±0.03 mW·cm-² and an open-circuit voltage of 0.61 V.After one week,the biofuel cell maintained 57%of its original power density.Our findings pave the way for the development of more efficient BFC using MWNTs@MOFs-C carbon composites as electrode supports.
