La Doped

La-doped Titania powders were synthesized by sol-gel method. The influence of dopant on the phase transformation temperature, Phase compositions, chemical states, microstructures and the visible light absorbable range of titania were investigated, which were characterized by X-ray diffractometer (XRD), transmission electron microscopy (TEM), energy dispersion X-ray spectrum in scanning transmission electronic microscope (STEM-EDS) and UV-Vis spectrophotometer (UV-Vis). The results show that the dopant of La3+ significantly inhibited the phase transition and grain growth of TiO2.With the increasing of calcination temperature, the grain orientation of TiO2 are from clutter into order and the light absorption band edge of TiO2 are blue shift. La3+-doped titania precipitate La4Ti19O24 and the second phase precipitated on the surface of TiO2 with irregular spherical.

Cotton fabrics were treated by one-step sol-gel method. The pure silica hydrosol and phosphorus-doped hydrosol were prepared with the addition of a hydrophobic hexadecyltrimethoxysilane to decrease the surface energy of cotton fabric. The thermal properties and water repellency of treated cotton fabric were characterized by thermo-gravimetric analysis, micro combustion, limiting oxygen index, and contact angle measurement. The results showed that cotton fabric treated by phosphorus-doped silica hydrosol had excellent flame retardance, and the water repellence was apparently improved with the addition of hexadecyltrimethoxysilane.
