摘要：A hybrid system of carbon nanotubes （CNTs） coated with poly （amidoamine） （PAMAM） dendrimer- encapsulated platinum nanoparticles （Pt-DENs） and glucose oxidase （GOx） was prepared through the layer-by-layer （LbL） self-assembly approach and then used as anode in enzyme-based biofuel cells （BFCs）. The assembly process was monitored by C-potential measurement, and the as-resulted Pt-DENs/CNTs nanocomposites were characterized by transmission electron microscopy （TEM）. The performance of electrodes modified by Pt-DENs/CNTs was also investigated by electrochemical impedance spectroscopy （EIS） and cyclic voltammetry （CV）. We found that the Pt-DENs]CNTs could enhance the electron trans- fer between the redox centers in enzyme and the electrode surfaces. Furthermore, by employing the Pt-DENs/CNTs modified electrodes as anode, the enzyme-based BFCs operated in a solution containing glucose generated an open-circuit voltage of approximately 640.0 mV and a maximum current density of about 90.0 μA/cmx, suggesting that Pt-DENs/CNTs may serve as an alternative anode to previously used noble metals in BFC applications.
