摘要 运用外加添加剂尿素的新技术,以水热法在玻璃基板上制备Ti O2微米球。采用SEM、TEM和XRD技术对产物进行表征,结果说明,生成的Ti O2晶体为锐钛矿型,Ti O2微米球的直径为2-3μm,它由大面积的Ti O2晶体自组装而成。制备产物的最佳条件是:0.15mol/LTi(SO4)2、Ti4+/添加剂摩尔比1/1、170℃、4h。 TiO_（2） microspheres were fabricated on the glass substrates via hydrothermal reaction by adding urea as additive.Scanning electron microscopy（SEM）,transmission electron microscopy （TEM） and X-ray diffractometry（XRD） are used to characterize these TiO_（2） microspheres,which confirm that the TiO_2 crystals are anatase.The diameters of the as-prepared microspheres are in the range of 2-3μm,which were a large scale self-assembly of TiO_（2） nanocrstals.Optimum synthesis conditions are 0.15mol/L Ti（SO_4）_2,Ti～（4＋）/additive=1/1,170℃,4h.
