| description | This study highlights the utilization of the Cr<sub>2</sub>S<sub>3</sub>-Cr<sub>2</sub>O<sub>3</sub>/P2ABT nanocomposite photoelectrode for efficient and highly sensitive photon absorption, enabling the generation of green hydrogen through the production of hot electrons upon illumination. The nanocomposite is synthesized via a one-pot reaction using K<sub>2</sub>Cr<sub>2</sub>O<sub>7</sub> and 2-aminobenzene-1-thiol monomer, and the presence of Cr<sub>2</sub>S<sub>3</sub>-Cr<sub>2</sub>O<sub>3</sub> is confirmed by XRD and XPS analysis within the composite. The optical properties of the Cr<sub>2</sub>S<sub>3</sub>-Cr<sub>2</sub>O<sub>3</sub>/poly-2-aminobenzene-1-thiol composite exhibit wide spectral coverage from UV to IR, with a bandgap of 1.6 eV. The diverse morphological behavior observed in the composite correlates with its optical properties, with the cleft spherical particles of the pure polymer transforming into rod-like structures embedded within the polymer matrix. The generated hydrogen gas demonstrates an impressive efficiency of 40.5 mole/10.cm<sup>2</sup>.h through electrochemical testing. The current density (J<sub>ph</sub>) values are evaluated under different light frequencies using optical filters ranging from 730 to 340 nm, resulting in Jph values of 0.012 and 0.014 mA.cm<sup>−2</sup>, respectively. These findings present a promising avenue as green hydrogen for industrial applications, leveraging the potential of the Cr<sub>2</sub>S<sub>3</sub>-Cr<sub>2</sub>O<sub>3</sub>/P2ABT nanocomposite photoelectrode. |
