| 摘 要： | 以钛酸四正丁酯((C4H9O)4Ti)水解沉淀的钛羟基氧化物和硝酸锶(Sr(NO3)2)为反应原料,以氢氧化钾(KOH)为矿化剂,以乙二醇((HOCH2)2)为溶剂,经200℃溶剂热反应得到了由纳米颗粒自组装形成的SrTiO3片状纳米结构。分别用XRD、SEM、TEM表征SrTiO3粉体的物相结构和微观形貌。通过光催化降解罗丹明B(RhB)对比研究了乙二醇溶剂热合成的纳米颗粒自组装SrTiO3片状纳米结构和水热合成的SrTiO3粉体的光催化性能,结果表明,乙二醇溶剂热合成的SrTiO3自组装片状纳米结构具有更加优异的光催化性能。

| Abstract: | Strontium titanate(SrTiO3) nanosheets self-assembled by nanoparticles were successfully synthesized by ethylene glycol solvothermal reaction route with titanium oxide hydroxyl as reaction materials and potassium hydroxide(KOH) as mineralizer at 200℃.The composition and morphology of the synthesized powders were investigated using XRD,SEM and TEM.The photocatalytic activities of the samples synthesized by hydrothermal and solvothermal method were studied through recording the degradation of Rhodamine B(RhB) in UV.The result shows that the SrTiO3 self-assembly nanosheets perform better photocatalytic activities. |
