摘　　要：采用微波水热法,以TiCl3为前驱物,NaCl为矿化剂,添加CTAB作为表面活性剂,在170℃下反应2h,制备出了纳米TiO2微球,用X射线衍射和扫描电镜对微球的晶型与形貌进行研究。结果表明,微球为金红石型,直径为2～3μm,微球由纳米棒组装而成,纳米棒直径为50nm,长度为500nm。Using TiCl3 as precursor,NaCl as mineralizer,TiO2 nano-microspheres were synthesized by self-assembly at 170 ℃ for 2 h using microwave-hydrothermal method with the presence CTAB as the surfactant.XRD and SEM were employed to characterize the crystal structure and morphology of the microspheres.The results show that the spheres are rutile with the diameters of 2-3 μm.The sphere is composed of radially aligned nano-rods with the diameter of 50 nm and length of 500 nm.
