| 제목 | Enhancing the performance of a CuFeO2/Cu2O composite system photocathode for solar hydrogen production |
| 초록 | PEC water splitting is one of ideal processes to produce H2 with sunlight. There are various materials that can be used as photocatalyst for PEC water splitting like TiO2, WO3, and BiVO4. Among them, CuFeO2 is a promising p-type semiconductor as a photocathode with many desired properties including the small band gap 1.55 eV to utilize solar spectrum effectively. Moreover, CuFeO2 consists of earth abundant elements, so it has advantages for mass production. Unfortunately, CuFeO2 is insufficient material to be used alone because of its low activity and difficulties to synthesis. Here, the pure delafossite CuFeO2 is synthesized through sol-gel method, and its activity has increased by making composite system with copper oxide. Additionally, several post modification plans are introduced such as modifying delafossite thickness layer, adding protective layer to increase stability, and doping to improve conductivity. |
