Abstract

A visible-light-active CuInSe₂:Zn/g-C₃N₄/TiO₂ nanowire (NW) photoelectrode was prepared by in situ growth of g-C₃N₄ on the surface of TiO₂ NWs, followed by drop deposition of Zn-doped CuInSe₂ quantum dots (CuInSe₂:Zn QDs). It has a 2.205 eV band gap and can absorb visible light. The as-prepared ternary hybrid nanocomposite CuInSe₂:Zn/g-C₃N₄/TiO₂ NWs shows high photon absorption and photocurrent generation efficiency, as well as a high bactericidal effect on Staphylococcus aureus.
