L-缬氨酸席夫碱金属配合物的合成及光催化性质

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C13H20Fe2+NO6、C13H20Cu2+NO6和C13H20Sn2+NO6,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,C13H20Fe2+NO6、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(C13H20Fe2+NO6、C13H20Cu2+NO6and C13H20Sn2+NO6) were designed,synthesized with L - valine and vanillin as starting materials and characterized by 1 H NMR,MS(EI),elemental analysis and so on.At 25 ℃,the degradation property of MB over the cata-lysts 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.C13H20Sn2+NO6had the best catalytic activity espe-cially.We forecast they are a kind of environmental friendly photocatalytic materials.
