Boron doped nanocrystalline diamond films (BDD) immobilized with photosensitive molecules have been studied as electrode material for reduction of nitrate in waste water. This process is one of the most important goals of the modern electrochemistry. The diamond thin films were deposited on silicon substrate by Hot Filament Chemical Vapour Deposition (HFCVD) technique. Manganese phthalocyanine has been used as photosensitive material for immobilization. The BDD electrode has been

The electrochemical properties have been studied by Cyclic Voltammetry (CV) at different experimental conditions in dark and under illumination. The results approve that the boron doped diamond electrode grafted with phthalocyanine serves as an efficient and stable electrode for nitrate reduction. The diamond electrode has wide potential range. The obtained results are promising for future electrochemical application.
