Özet

Hydrogen could be generated from both renewable and non-renewable sources of energy. Using

nonrenewable energy sources to produce hydrogen will result in greenhouse CO2 gas emissions and

cause global warming. Photocatalytic systems for generating hydrogen from solar energy have a great

deal of potential to solve the global warming problem because of the totally renewable green source of

sun and water. Because of its superior properties, such as a proper and narrow bandgap, better

chemical stability, non-toxic, photo-corrosion resistance, and suitable optimum conduction and valance

band potentials, the tin disulfide (SnS2) photocatalyst has great potential to be used for producing H2

from the splitting of water via solar energy. In this study, SnO2 powders were successfully thermally

sulfurized to SnS2 powders at 500°C for 24 hours under an Argon (Ar) atmosphere. The XRD analysis

verified the hexagonal SnS2 crystals. UV-vis spectroscopy was used to determine the band gap value

of the generated powder, which is 2.24 eV.
