Fabrication of TiO2/MS (M = Pb, Zn) core–shell coaxial nanotube arrays and their photocatalytic properties

Abstract

In this work, TiO₂/MS (M = Pb, Zn) core–shell coaxial nanotube arrays were prepared by a simple method of liquid deposition using anodic aluminium oxide templates. The mechanism of the formation of TiO₂/MS (M = Pb, Zn) coaxial nanotubes is discussed here. Compared to bare TiO₂ nanotubes, TiO₂/PbS and TiO₂/ZnS composite nanotubes showed improved photocatalytic properties and analysis of such results was also conducted.
