|
摘要
以L-缬氨酸和香兰素为起始原料,设计并合成了3种L-缬氨酸席夫碱金属配合物C_(13)H_(20)Fe~(2+)NO_6、C_(13)H_(20)Cu~(2+)NO_6和C_(13)H_(20)Sn~(2+)NO_6,采用1H NMR、MS(EI)和元素分析等表征其结构。以3种L-缬氨酸席夫碱金属配合物作为光催化剂,研究25℃下,C_(13)H_(20)Fe~(2+)NO_6、C13H20Cu2+NO6和C13H20Sn2+NO6催化剂在甲醇与水混合溶液中的亚甲基蓝降解性能。结果表明,3种催化剂对亚甲基蓝均有降解活性,其中,C13H20Sn2+NO6催化剂的亚甲基蓝降降解性能最好,预测这是一类潜在的环保性光催化材料。
Three novel photocatalytic materials( C_(13)H_(20)Fe~(2+)NO_6、C_(13)H_20Cu~(2+)NO_6 and C13 H20 Sn2 +NO6)were designed,synthesized with L-valine and vanillin as starting materials and characterized by1 H NMR,MS( EI),elemental analysis and so on. At 25 ℃,the degradation property of MB over the catalysts was studied in the mixed solution of methanol and water. The results showed that all of the catalysts had certain degradation activity to MB,respectively. C13 H20 Sn2 +NO6 had the best catalytic activity especially. We forecast they are a kind of environmental friendly photocatalytic materials.
