| description | This study describes the synthesis of delafossite, CuFeO<sub>2</sub>, as a primary photocatalytic material for hydrogen generation. A photoelectrode, CuFeO<sub>2</sub>/CuO/Cu, was prepared by combusting a Cu foil dipped in FeCl<sub>3</sub> in ambient air. This photoelectrode showed excellent optical behavior for the hydrogen generation reaction from sewage water, producing 90 µmol/h of H<sub>2</sub>. The chemical structure was confirmed through XRD and XPS analyses, and the crystalline rhombohedral shape of CuFeO<sub>2</sub> was confirmed using SEM and TEM analyses. With a bandgap of 1.35 ev, the prepared material displayed excellent optical properties. Electrochemical measurements for H<sub>2</sub> gas generation were carried out using the CuFeO<sub>2</sub>/CuO/Cu photoelectrode, comparing the effect of light and dark and monochromatic wavelength light. The electrode exhibited significant enhancement in light compared to dark, with current density (J<sub>ph</sub>) values of −0.83 and −0.1 mA·cm<sup>−2</sup>, respectively. The monochromatic light also had a noticeable effect, with the J<sub>ph</sub> value increasing from −0.45 to −0.79 mA·cm<sup>−2</sup> as the wavelength increased from 640 to 390 nm. This system is cheap and durable, making it a promising solution for hydrogen gas fuel generation in the industry. |
