Synthesis And Characterization Of Electrodes N-Tio2Ti For Chemical Oxygen Demand Sensor With Visible Light Response Flow

Abstract There had been done a thin layer preparation of N-TiO2 nano-sized which is attached to the substrate Ti Plat. Preparation of thin layers films N-TiO2 was done by dip coating into the sol-gel prepared by reflux and then calcined at 4500C. Characterization was conducted towards the film by DRS XRD FTIR SEM and potentiostat. DRS measurement results indicated wavelength in the visible region XRD measurement showed that the resulting film was dominated by the N-TiO2 in the anatase form and has a crystal size crystallite size of 13.47 nm. While the results of the FTIR characterization indicated Ti-O bond -NO and Ti-N. Meanwhile SEM measurements show that small crystal size. Photoelectrochemical test with potentiostat by placing the film N-TiO2Ti as the working electrode produces light flow response to N-TiO2Ti. This system can be developed into a useful sensor for determining COD in a way that has never existed before.
