The morphology characterization of nitrogen and magnesium doped with titanium dioxide (TiO2) using field emission scanning electron (FESEM) for photocatalytic study

Abstract

Previous studies attempted to modify the electronic structure of TiO2 in order to broaden the sensitivity to visible light region from the UV light region to visible light region. In this matter, it is very important to identify the effect of parameters that will be affecting the production of photocatalyst as it will also eventually affect the photocatalytic activity. Some of the advantages of dopants are they are effective and efficient. Some of the parameters that could be identify are such as effect of metal and non-metal dopant, the dopant concentration, loading of photocatalyst during photocatalytic activity, calcination temperature during the heating treatment, initial concentration of pollutant and others. In this study, the parameters that will be studied are including type of dopant (metal and non-metal dopant), calcination temperature, and the dopant concentration. In this paper, the temperature was varied for 300°C, 500°Cand 700°C by using different weight percentage which are 0.5 wt. %, 0.7 wt. % and 0.9 wt. %. From FESEM result, shows the temperature affect the morphology of Nitrogen and Magnesium-Doped with Titanium Dioxide (TiO2).
