| 摘 要： | 以硝酸锶Sr（NO3）2]和结晶四氯化锡（SnCI4·5H2O）为原料,有机碱四甲基氢氧化铵N（CH3）4OH]为矿化剂,采用共沉淀法制备SrSnO3纳米粒子。用XRD和IR对样品的物相和结构进行表征,并研究了对亚甲基蓝废水的光催化降解性能。结果表明:用该法在500℃煅烧1h时制备的纯立方相SrSnO3纳米晶粒在可见光照下具有良好的光催化性能。催化剂浓度为60mg/L,反应时间为100min时,降解率可达94%。

| Abstract: | Perovskite SrSnO3 nanoparticles were synthesised by co-precipitation method using Sr（NO3）2 and SnCl4 · 5H2O as materials and the organic base tetramethyl ammonium hydroxide N（CH3）4OH]as mineralizer.The phases and microstructure were characterized by XRD and IR.Its photocatalytic activity to the methylene blue was investigated.When the pure cubic phase SrSn03 nanoparticles synthesized at 500℃for 1h was irradiated by the visible light,the photo-degradation of methylene blue could reach to 9A%as the concentraion of photocatalyst was 60mg/L and the reaction time was 100min. |
