摘　　要：在最佳条件下(TiCl3 0.15 mol/L NaCl饱和溶液,170℃,4 h,含O添加剂/Ti摩尔比1/10)用水热法在玻璃基板上制备TiO2材料。SEM和XRD技术表征结果说明,生成的TiO2晶体为金红石型。与尿素相比,加酸性含O添加剂不能生成TiO2纳米棒阵列薄膜,但能生成的TiO2微米球或微米花,微米球或花由纳米棒自组装而成。加中性含O添加剂所生成的TiO2材料的形貌最差。The TiO2 materials were fabricated on the glass substrates at the optimal conditions （TIC13 0.15mol/L NaCl saturated aqueous solution,70℃ ,4h,molar ratio of O-additive/Ti 1/10）.The products are characterized by SEM and XRD techniques which revealed that the as-prepared TiO2 crystals are rutile. Compare with the urea,the TiO2 thin films cannot be fabricated but can only the TiO2 microspheres or microflowers be prepared by adding the acidic O-additives,the microspheres or flowers are large scale of assembed of TiO2 nanorods. When adding the neutral O-additives,the morphology of the as-prepared TiO2 materials are the worst.
