Effect of Calcination Temperature on Synthesis of N-Fe-TiO₂ for Photocatalytic Degradation of Methylene Blue under Visible Light

Abstract:

Effect of calcination temperature on the synthesis of N, Fe codoped TiO₂ for the photodegradation of methylene blue under ordinary visible lamps was investigated. The photocatalyst were prepared using solgel method where titanium isopropoxide was used as precursor of titania. The calcination temperatures were varied from 450 to 600°C. The prepared photocatalysts were characterized by using XRD, FE-SEM and FTIR to determine their physical properties. The results from XRD proved that photocatalysts calcined at 600°C possessed perfect properties in phase and crystal size. FE-SEM image analysis revealed the formation of the fine spherical particles and the FTIR analysis verified the presence of dopants at various calcination temperatures. The effectivity of photocatalysts was tested by performing a standard batch photocatalytic degradation experiment with methylene blue as a model pollutant under ordinary visible light. The result showed that N and Fe codoped photocatalyst calcined at 600°C (1.0 % N, Fe-TiO₂-600) yielded a maximum of 80.50% methylene blue degraded within five hours of irradiation time.
