10.Summary of Research Results
|
Highly boron-doped diamond electrodes have received attention of several electrochemists and electroanalysts in the past few decades owing to their superior electrochemical properties that are significantly different from those of the other materials such as glassy carbon (GC), highly oriented pyrolytic graphite (HOPG) and metals, which have been used as electrode materials for many years. GC electrodes are conventionally used for the electrochemical applications due to their relatively wider potential window compared to other electrode materials such as platinum and gold. GC is mainly composed of sp2-type carbon and the electronic and electrochemical properties depend on several factors including microstructure and carbon-oxygen functional groups. The electrochemical properties of conducting diamond electrodes, composed of sp3-type carbon include, a wide potential window in aqueous and non-aqueous electrolytes, very low capacitance and extreme chemical stability. These properties prove the superiority of diamond over the other electrode materials for electrochemical applications. In this program, including fundamental studies and application of diamond in various fields were taken considered. The fundamental studies include the studies involving growth of polycrystalline diamond films and homoepitaxially grown diamond films using several dopants to obtain n-type and p-type diamond. These films thus obtained were characterized by use of several techniques for their use in electronics and electrochemistry. The other aspect proposed is the application of diamond in electroanalysis and electrosynthesis, as electrochemical detector making use of high over potentials for hydrogen and oxygen evolution, in vivo biosensor, electrochemical treatment of industrial wastewater and photoelectrochemical applications. |
