| 摘 要： | 根据蚕丝丝素蛋白等电点约4.5的特性,以CdCl_2·2.5H_2O和CH_3CSNH_2为原料,将CdCl_2用明胶包覆后置于定制的丝素膜反应器中,在pH=6条件下制得纳米 CdS。经 UV、AFM表征,CdS的平均粒径为 5～10 nm,其对活性染料 KD-8B有较好的光催化降解活性。

| Abstract: | Since the isoelectric point of the silk fibroin protein is about pH =4.5, and a cadon exchanger can be fixed with the silk membrane above pH =4.5, Nano-sized CdS was synthesized by Cd2+ ion through silk fibroin protein membrane. Their structures were characterized by UV,AFM. It is showed that CdS nanoparticles have a uniform particle size of 5 -10nm and nanometer CdS has a good photocatalytic activity through photocatalytic degradation experiments |
