Abstract
We describe the preparation of laccase/single-walled carbon nanotube bioconjugates, their application for the modification of electrodes and application of the electrodes as cathodes for the catalytic reduction of oxygen in a hybrid biofuel cell with Zn anode. Carbon nanotubes functionalized with aminoethyl residues, activated and reacted with laccase show high bioelectrocatalytic activity and are promising for the biofuel cell applications. The power density of the cell was 1 mW cm− 2 at working voltage of 0.8 V. The open circuit voltage of this hybrid cell was as high as 1.5 V.
