چکیده انگلیسی
We have synthesized S (S4+)-doped and N (N3â)-doped TiO2 photocatalysts. S-doped and N-doped TiO2 loaded with Fe2O3 nanoparticles have also been prepared. These photocatalysts showed activity under a wide range of wavelengths of irradiation. Action spectra of photochemical reaction rate as a function of the incident light wavelength for oxidation of acetic acid on S-doped TiO2 was studied.The photocatalytic activities of S-doped and N-doped TiO2 photocatalysts loaded with Fe2O3 nanoparticles for oxidation of acetic acid in aqueous phase and acetaldehyde in gas phase are markedly improved compared to those of doped TiO2 without loading of Fe2O3 nanoparticles under a wide range of incident light wavelengths. The optimum amount of Fe2O3 nanoparticles loaded on S-doped TiO2 particles was different from that on N-doped TiO2 for oxidation of organic compounds. The relationship between reaction rate of photocatalytic oxidation of acetaldehyde on doped TiO2 loaded with Fe2O3 nanoparticles and amount of Fe2O3 nanoparticles is discussed.
