摘　　要：采用化学共沉淀法在金红石型Ti O2表面包覆Zn O,制备了纳米Ti O2/Zn O复合紫外线屏蔽粉体。利用XRD、TEM等手段对所得的样品进行了表征,得出相对最佳制备条件为:(NH4)2CO3为沉淀剂,m(Zn O)∶m(Ti O2)=1∶1,反应温度为80℃,在400℃下煅烧2 h,此条件下制备的纳米Ti O2/Zn O复合粉体具有较好的纳米效应。The surface of rutile nano- Ti O2 was coated by Zn O through chemical coprecipitation to prepare Ti O2/Zn O nano- composite powders with UV- shielding ability. The obtained samples were characterized by XRD and TEM. The suitable condition for preparation was given：（NH4）2CO3used as precipitant, m（Zn O）∶m（Ti O2） = 1 ∶1, the reaction temperature 80 ℃, and calcination at 400 ℃ for 2 h. The Ti O2/Zn O nano- composite powders prepared under this condition exhibit anticipated nanometer effects.
