摘要: AbstractIn order to extend the visible light response of ZnO, ZnO/CuS nanocomposite with heterostructure was prepared by a simple two-step hydrothermal synthesis. The as heterostructured characterised SEM, photoluminescence, ultraviolet–visible spectroscopy and X-ray diffraction. On other hand, chitosan is considered very promising natural biopolymer. It holds not only abundant resource low cost but also has excellent adsorption properties broad range organic pollutants some heavy metal ions. To improve nanocomposite, water soluble containing carboxyl groups synthesised graft copolymerisation. Surface modification carried out utilising self-assembly process between hydroxyl chitosan. Comparative tests before after surface were performed ...
