Abstract
Glucose biofuel cells are considered a promising power supply with a competent long-term stability and power density. In this respect, novel modified electrodes were fabricated for biofuel cell based on electrochemical polymerization of organic monomer on glassy carbon electrodes. An investigation was carried out on the catalytic electrooxidation of glucose in alkaline media utilizing conducting polymer electrodes modified by incorporation of palladium-nanoparticles (PdNPs) and platinum-nanoparticles (PtNPs) onto poly(1,8-aminonaphthalene) (1,8-PDAN). SEM and EDX analysis depict the homogenous distribution of the metal nanoparticles onto the polymer film. The prepared Pd/PDAN/GC, Pt/PDAN/GC and Pt-Pd/PDAN/GC modified electrodes showed an excellent electroanalytical performance with an excellent operation/storage stability. The voltage response exhibited a linear relationship with increase in glucose concentration (2.0μM to 25.0mM), with a sensitivity of 160 μA/mM/cm2. Higher activity and stability of Pt-Pd/PDAN/GC composite electrode were observed. These versatile kind of modified electrodes render the potential candidates for developing a new generation of glucose biofuel cells.
