Efficient visible-light photocatalytic H2 generation of TiO2 by CuPc modification |
| 초록 |
The advantage of copper Pc (CuPc) deposition onto titanium dioxide (TiO2) semiconductor photocatalyst for enhanced hydrogen generation under irradiation at the visible-light range has been investigated. The deposition loading varied with different mass of CuPc. The resulting CuPc/TiO2 composite photocatalysts were characterized by using transmission electron microscopy (TEM), electron energy loss spectroscopy (EELS), ultraviolet-visible diffuse reflection spectroscopy (DRS), and energy dispersive X-ray spectroscopy (EDS). The photocatalytic hydrogen evolution was investigated for CuPc/TiO2 under visible-light irradiation (＞420nm). The photocatalytic analysis revealed that the CuPc layer was crucial for higher hydrogen gas evolution. This result demonstrated CuPc/TiO2 as a highly efficient visible-light photocatalyst for hydrogen-gas evolution. |
