Fabrication of (GO_x/Pt-DENs)n/CNTs Nanocomposite and Their Electrochemical Properties for Anode in Biofuel Cell

摘要

In this paper, a method of carbon nanotube coated with the dendrimer encapsulated platinum nanoparticles (Pt-DENs/CNTs ) was introduced, and the properties of enzyme electrode modified by the Pt-DENs/CNTs were investigated. The formation of the self-assembled (GOx/Pt-DENs)_n/CNTs construction was explored by high resolution transmission electron microscopy (HRTEM). And the results indicated that the uniform growth of the layer-by-layer nanostructures onto carboxyl-fanctionalized CNTs. The electrochemical properties of the enzyme anode modified by (GOx/Pt-DENs)_n/CNTs, which act as biofuel cell anode, was studied by electrochemica measurements.
