Abstract:

 

This paper presents a comparative study of nanomaterial modified glassy   carbon paste electrodes (GCPEs) used as bioanodes in enzymatic biofuel   cells. The developed bioanode electrodes were obtained by modification of   composite GCPEs with glucose oxidase (GOx) and different nanomaterials like   manganese(IV) oxide nanoparticle (MnO22_{2} np) and aluminum titanate   (Al22_{2}O33_{3}-TiO2)2)_{2}) bimetallic nanostructure. These nanostructures   were utilized in a GCPE-based enzymatic bioanode construction for the first   time. P-benzoquinone mediator was used for the electron transfer between   enzyme redox center and bioanode electrode where glucose analyte was used as   substrate. A laccase-modified plain GCPE was used as biocathode electrode.   Then these electrodes were combined in a membraneless biofuel cell (BFC).   The power densities of single cell BFCs were 0.619 μμ\mu W cm−2−2^{-2} (at 34   mV) for the plain GCPE, 4.57 μμ\mu W cm−2−2^{-2} (at 76 mV) for the   GOx/MnO22_{2} np/GCPE, and 1.41 μμ\mu W cm−2−2^{-2} (at 36 mV) for the   GOx/Al22_{2}O33_{3}--TiO22_{2}/GCPE. As a result, it has been observed that   the MnO22_{2} np/GOx/GCPE exhibits the best power density. The current   density value of this bioanode has also been examined and found to be 99.21   μμ\mu A cm−2−2^{-2} in phosphate buffer solution (pH 7) with maximum open   circuit potential of 294 mV.
