A radially controlled ZnS interlayer on ultra-long ZnO–Gd₂S₃ core–shell nanorod arrays for promoting the visible photocatalytic degradation of antibiotics

Abstract

shell-layered (∼40 nm) ZnO-ZnS core-shell structures, respectively. The core-shell geometry and the shell-wall thickness with maximized contact interface afforded increased light absorption in the visible region and effectively retarded the recombination rate of the photoinduced charge carriers by confining electrons and holes separately, thus providing advantages in terms of the degradation of the pharmaceutical residue tetracycline and the industrial pollutant 4-nitrophenol in wastewater.
