High-Efficiency Photon-Capturing Capability of Two-Dimensional SnS Nanosheets for Photoelectrochemical Cells

Cost-effective, abundant, and non-toxic SnS nanosheet semiconductors can be used as water-splitting cells. Herein, a photoanode based on high-purity highly crystalline nanosheets was fabricated. We sodium thiosulfate (Na2S2O3·5H2O) stannous chloride (SnCl2·2H2O) the tin sulfur source materials, in place of SnCl4 H2S gas, respectively, which have been previous studies. This gas-free fabrication process represents new, environment-friendly method that reduce manufacturing cost nanosheets. The fabricated samples were characterized via X-ray diffraction, ultraviolet-visible spectroscopy, XPS, scanning electron microscopy, Raman analyses. XPS result indicated no Sn0 or Sn4+ S3 nanosheet; SnS. These results with XRD show has high phase purity crystallinity. Its direct optical band gap is 1.31 eV, its lattice parameters are similar to those standard nanosheet-based exhibited maximum saturation photocurrent 6.86 mA cm?2 at 0.57 V versus Ag/AgCl, stability. most effective for photocatalytic cell attained an increase surface area developed electrical conduction. attributed thermal annealing, eliminates nanoparticle imperfections. study confirms excellent candidates applications.
