    Synthesis of SnS2 photocatalyst for photocatalytic hydrogen production
    (2022-06-30) OK, ALAADDİN CEM; SARIOĞLU, CEVAT; Ok A. C., Sarıoğlu C.
    Hydrogen could be generated from both renewable and non-renewable sources of energy. Usingnonrenewable energy sources to produce hydrogen will result in greenhouse CO2 gas emissions andcause global warming. Photocatalytic systems for generating hydrogen from solar energy have a greatdeal of potential to solve the global warming problem because of the totally renewable green source ofsun and water. Because of its superior properties, such as a proper and narrow bandgap, betterchemical stability, non-toxic, photo-corrosion resistance, and suitable optimum conduction and valanceband potentials, the tin disulfide (SnS2) photocatalyst has great potential to be used for producing H2from the splitting of water via solar energy. In this study, SnO2 powders were successfully thermallysulfurized to SnS2 powders at 500°C for 24 hours under an Argon (Ar) atmosphere. The XRD analysisverified the hexagonal SnS2 crystals. UV-vis spectroscopy was used to determine the band gap valueof the generated powder, which is 2.24 eV.
