| Outline of Final Research Achievements |
The CNTs have good electrical/thermal conductivity and they are considered to be a potential candidate of the electrode materials for the electrical storage devices. We develop the hybrid electrodes with a three-dimensional network structure with CNT for graphene supercapacitors. The CNTs are in between the inter-layer space of graphene sheets as a spacer to prevent effectively restacking of graphene that often limits seriously the electrochemical performance of graphene supercapacitors. The CNTs also act as conductive binders between graphene sheets to improve the electrical conduction of the electrode. On the other hands, CNTs modified electrodes have the large specific surface area and the abundant functional groups and show specific catalytic action in the electrochemical reactions of certain substances. The high sensitivity, selectivity, and stability of the sensor demonstrated its practical application for a simple, rapid and economical determination of trace levels.
