Hybrid layered double hydroxides-polypyrrole composites for construction of glucose/O2 biofuel cell.

Two layered double hydroxides, Zn2Cr-ABTS and Zn2Al-Fe(CN)6 LDH, were synthesized and characterized by x-ray diffraction and FTIR spectroscopy to confirm the intercalation of redox anions between inorg. layers. These redox active hybrid materials were used to elec. connect laccase (Lac) and glucose oxidase (GOx) in biofuel cell devices. Co-immobilization of hybrid LDH and enzymes was performed by entrapment in electropolymd. films of polypyrrole deposited on porous C tubular electrodes. Lac/Zn2Cr-ABTS cathodic electrode allows the electroenzymic redn. of O2, whereas the anodic electrode GOx/Zn2Al-FeIII(CN)6was used for the electroenzymic oxidn. of glucose. With a two compartment configuration, a max. power d. of 45 $μ$W cm-2was obtained at 0.2 V. [on SciFinder(R)]
