Research on Biofuel Cells Based on Novel Nanoporous Carbon Composites
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.
