摘　　要：具有独特钙钛矿结构的钛酸锶由于其独特的光学性能已经受到广泛关注。本文尝试以廉价、无毒的铝化合物作为掺杂剂,进行铝掺杂钛酸锶光催化剂的合成。合成的干凝胶于500℃环境下煅烧3 h合成SrTiO_(3)光催化剂,表征结果显示:合成的光催化剂以立方钛酸锶型为主、部分无定形和部分金红石型TiO_(2)。Al元素掺杂改进了形貌且出现部分片状形貌。Strontium titanate(STO)has a unique perovskite structure.STO attractes much attention due to its unique optical properties.In this paper,we try to synthesize aluminum doped strontium titanate photocatalyst by using cheap and non-toxic aluminum compounds as dopants.STO photocatalyst was synthesized by calcination at 500℃for 3 hours.The characterization results showed that the STO was cubic strontium titanate with part of amorphous STO and rutile TiO_(2).Al doping improves the morphology and some lamellar morphology appears.
