Çó·ÒëÒ»¶Î»°---------Ó¢ÎÄ£¬Ð»Ð»£¡ ×£ÖÐÇï¿ìÀÖ£¡ As the wire diameter decreases from the nanometer to the angstrom (atomic) scale, the surface to volume ratio increases dramatically. In respect of the atomic wires with a diameter of only about one unit cell, almost all the atoms are on the surface, which will significantly enhance the photocatalytic activities. We will first develop chemical synthesis methods for the ultrathin non-metal-doped TiO2 1D nanomaterials, which emphasize the formation and controlled condensation of precursors. Secondly, we will elucidate the effects of size and doping of the ultrathin wires on their photocatalytic properties in the visible region of the electromagnetic radiation. Finally, to improve the stability and reusability of the photocatalysts, we will use silica mesoporous materials or nafion membranes as a support to disperse the ultrathin wire based photocatalysts. |
