Tóm tắt

An Al2O3 overcoated TiO2:N layer was synthesized using the solgel method. XRD, SEM and UV-vis measurements were used to study the structure and optical properties of the material. The XRD results indicated that the TiO2:N layer was identified only as an anatase phase. SEM images showed that the diameter of particles was around 15-30 nm depending on the NH(C2H4OH)2 concentration in the sol solution. UV-vis spectrums suggested that a TiO2:N/Al2O3 sample can absorb visible light. These results indicate that fabricated material degrades CO, NO better than Degussa P25 commercial TiO2 when exposed to natural light.
