Preparation of Nanometer Cadimium Sulfide Particle through Silk Fibroin Membrane and its Photocatalytic Activity

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 char
