Facile synthesis of 3D flower-like Cu2-xSe nanostructures via sacrificing template method and the excellent antibacterial activities

Abstract

Three-dimensional (3D) flower-like Cu2-xSe film with hexagonal nanosheet hierarchical structure has been synthesized for the first time from a 3D flower-like CuO film precursor through a facile sacrificing template method at room temperature. The product was characterized and its formation mechanism was explored based on series of control experiments, combining with crystal structure analysis. The optical property and photodegradation activities of the Cu2-xSe film on three dye solutions were studied. Particularly, for the first time its antibacterial activities were explored. The results show that the 3D flower-like Cu2-xSe is assembled by numerous hexagonal nanosheets with thicknesses of about 50 nm. The flower-like Cu2-xSe displays excellent antibacterial activities to both staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). For the first time, the experimental results confirm that the antibacterial rate depends on the Cu(II) ions concentration which is closely related with the Cu2-xSe quantity and incubation time.
