Synthesis and Photocatalytic Performance of ZnIn2S4 Nanotubes and Nanowires

ZnIn2S4 nanotubes and nanowires have been selectively fabricated via a convenient one-step wet-chemical approach by using porous polycarbonate membrane as a hard template. The wall of nanotubes is as thin as 5 nm, and the diameter of them is 200 nm. Formation mechanism of ZnIn2S4 nanotubes and nanowires is also discussed according to the experimental results. The structure, morphology, and composition properties of the as-prepared samples were characterized using X-ray powder diffraction, UV-vis spectrophotometer, transmission electron microscopy, energy dispersive X-ray spectrometry, and scanning electron microscopy.
