以硝酸锶[Sr(NO_3)_2]和结晶四氯化锡(SnCI_4·5H_2O)为原料,有机碱四甲基氢氧化铵[N(CH_3)_4OH]为矿化剂,采用共沉淀法制备SrSnO_3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SrSnO_3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%。 The strontium nitrate [Sr (NO_3) _2] and tin tetrachloride (SnCI_4 · 5H_2O) were used as raw materials and the organic base, tetramethylammonium hydroxide [N (CH_3) _4OH], was used as mineralizer to prepare SrSnO_3 Nanoparticles. The phase and structure of the sample were characterized by XRD and IR. The photocatalytic degradation of methylene blue wastewater was also studied. The results show that the pure cubic SrSnO 3 nanocrystals prepared by this method calcined at 500 ℃ for 1 h have good photocatalytic activity in visible light. The catalyst concentration of 60mg / L, the reaction time of 100min, the degradation rate of up to 94%.
