摘要
以结晶四氯化锡(SnCl4.5H2O)和乙酸钡[Ba(CH3COO)2]为原料,以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BaSnO3光催化剂,并研究了其对亚甲基蓝溶液的光催化性能。结果表明:在可见光照射下,BaSnO3光催化剂对亚甲基蓝溶液有明显的光催化降解作用。当催化剂浓度为40mg/L,反应时间为100min时,降解率可达93%以上。
The nanoparticles of BaSnO3 were prepared by a co-precipitation method using Ba（CH3COO）2 and SnC14 · 5H20 as materials, the organic base tetramethyl ammonium hydroxide [N（CH3）4OH] as a mineralizer. Its photocatalytic activity for the methylene blue was investigated. When the catalysts of Cube BaSnO3 nanoparticles were irradiated by the visible light, the photo- degradation of methylene blue could reach to 93% as the concention of photocatalysts was 40mg/L and the reaction time was 100min.
