摘要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(R-g), has been successfully determined by Shull-Roess method. The main peak of M( R-g) at 25degreesC is located at 2.3 nm, corresponding to a spherical diameter of 5.9nm, while it increases to 3.2 nm at 80degreesC, corresponding to a spherical diameter of 8.2 nm. 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.
