Poly(dibenzo[b,d]thiophene-S,S-sulfone), known as P10, boasts excellent hydrogen evolution rate(HER) due to the hydrophilicity of its sulfone group. However, its major drawback is its poor stability in reaction solutions, impacting photocatalyst durability. In this study, a method of synthesizing polymer nanoparticles was chosen to enhance stability compared to bulk polymer and thereby improve the durability of photocatalysts. As a result, the stability of the photocatalyst was improved, and a significantly reduced photocatalyst size was achieved compared to the existing polymer, which was advantageous for hydrogen evolution. Additionally, optical analysis was conducted to compare the different properties of the bulk polymer and the nanoparticles. Finally, the HER was measured and compared in both bulk and nanoparticle states. These results suggest that the photocatalyst nanoparticles can be a system that possesses both stability and hydrogen evolution capability.
