Graphene Applied in Production of Recyclable Electrodes
Tehran, Iran | Posted on December 13th, 2014The ability to be used a few times by polishing the surface of the electrodes is the most important advantage of the product. Medical and diagnosis clinics and electronics industries can employ the results of the research.
One of the problems in normal modified electrodes is their need to be modified all the time. Therefore, electrodes that are modified in volume manner should be used to solve this problem. Carbon ceramic electrode is one of these electrodes. In this research, graphene was used in the structure of sol-gel instead of graphite to modify chemical and physical properties and increase the performance of carbon ceramic electrode.
The recyclable modified electrode can be used in the production of electrochemical sensors and biosensors. The sensitivity of sensors increases due to the use of graphene instead of graphite.
In this research, graphene was used for the first time in the structure of sol-gel-based electrodes. Graphene has many advantages over graphite and carbon nanotubes. It is a semi-conductor with zero band gap, and therefore, it has extraordinary high electrical conductivity. In addition, it has very desirable mechanical strength (about 200 times of steel) although it is very light.
Based on the results, the produced electrochemical sensor has high sensitivity, low detection limit and appropriate repeatability. It also has lower potential for the electrocatalytic oxidation of ascorbic acid in comparison with carbon ceramic electrode.
Results of the research have been published in Microchimica Acta, vol. 181, issue 15-16, 2014, pp. 1879-1885.
