Doped Titania

P-doped titania was synthesized by a one step hydrothermal method and sol-gel method, which is characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The samples prepared by hydrothermal method demonstrate higher photocatalytic activity toward the degradation of methylene blue under xenon lamp which has similar spectra to solar light, and also is much superior to that of the commercial P25. The as prepared P-doped titania shows a small particle size (the minimum reaches to 4.5 nm). In addition, the samples prepared by hydrothermal treatment could severely influence the crystal lattice structure. Morever, P-doped titania can further enhacnce the photocatalytic activity effectively, and hydrothermal treatment is a very suitable method for the synthesis of P-doped titania. This excellent performance could endow the as-prepared P-doped titania potential in purifying wastewater.

One Step

Multiwalled carbon nanotubes (MWCNTs) were synthesized using arc discharge method at a magnetic field of 430 G and purified using HNO3/H2O2. Transmission electron micrographs revealed that MWCNTs had inner and outer diameter of ~2 nm and ~4 nm, respectively. Raman spectroscopy confirmed formation of MWCNTs showing G-band at 1577 cm−1. ZnFe2O4 and ZnFe2O4/MWCNT were produced using one step hydrothermal method. Powder X-ray diffraction (XRD) confirmed the formation of cubic spinel ZnFe2O4 as well as incorporation of MWCNT into ZnFe2O4. Visible light photocatalytic degradation of methylene blue (MB) was studied using pure ZnFe2O4 and ZnFe2O4/MWCNT. The results showed that ZnFe2O4/MWCNT composite had higher photocatalytic activity as compared to pure ZnFe2O4. After irradiation for 5 hours in the visible light, MB was almost 84% degraded in the presence of ZnFe2O4 photocatalyst, while 99% degradation was observed in case of ZnFe2O4/MWCNT composite. This enhancement in the photocatalytic activity of composite may be attributed to the inhibition of recombination of photogenerated charge carriers.

Doped Titania

Phosphor-doped titania nanoparticles were synthesized by a one step hydrothermal method. These samples which prepared by hydrothermal method exist in anatase phase has much higher photocatalytic activity for methylene blue (MB) degradation. In addition, MB degradation performance of the hydrothermal ones is also superior to that of the commercial P25. The resulting materials were characterized by X-ray diffraction (XRD), nitrogen physical adsorption at 77 K, X-ray photoelectron spectroscopy (XPS), etc. It can conclude the hydrothermal method proves to be more suitable to improve the photocatalytic performance.
