In Situ Synchrotron Small Angle X-ray Scattering Studies of TiO2 Colloid at Elevated Temperature

  • The suspension colloids of the wide-gap semiconductor TiO2 nano-particles in aqueous solution at elevated temperature have been studied by in situ small angle X-ray scattering using synchrotron radiation.It is found that the Guiner plot of the scattering intensity shows an upward concave behaviour at lower scattering vectors,being representative of a polydispersive system.The size distribution of gyration radius of TiO2 nano-particles in aqueous solution,M(Rg),has been successfully determined by Shull-Roess method.The main peak of M(Rg) at 25°C is located at 2.3nm,corresponding to a spherical diameter of 5.9nm,while it increases to 3.2nm at 80°C,correspoding to a spherical diameter of 8.2nm.This size distribution of TiO2 nanoparticle in solution is useful to understand the photo-electron properties and the stabilities of the dye sensitised TiO2 nanoparticle solar cell.

Abstract: The suspension colloids of the wide-gap semiconductor TiO2 nano-particles in aqueous solution at elevated temperature have been studied by in situ small angle X-ray scattering using synchrotron radiation.It is found that the Guiner plot of the scattering intensity shows an upward concave behaviour at lower scattering vectors,being representative of a polydispersive system.The size distribution of gyration radius of TiO2 nano-particles in aqueous solution,M(Rg),has been successfully determined by Shull-Roess method.The main peak of M(Rg) at 25°C is located at 2.3nm,corresponding to a spherical diameter of 5.9nm,while it increases to 3.2nm at 80°C,correspoding to a spherical diameter of 8.2nm.This size distribution of TiO2 nanoparticle in solution is useful to understand the photo-electron properties and the stabilities of the dye sensitised TiO2 nanoparticle solar cell.
