제목 | CdS nanograin sensitized Zr:Fe2O3 nanorod array for highly efficient solar-light-driven photoelectrocatalytic performance |
초록 | Well-defined CdS nanograins sensitized Zr:Fe2O3 nanorods with enhanced photoelectrocatalytic performance are synthesized on F-doped SnO2(FTO) using hydrothermal method. Owing predominantly to the appropriate band positions and charge collection in Zr:Fe2O3 nanorods, CdS/Zr:Fe2O3 heterostructure exhibit 1.7 times improved photocurrent density compared to Zr:Fe2O3. Unfortunately, CdS nanograins sensitized Zr:Fe2O3 nanorod arrays suffers from instability problem. Furthermore, Ni(OH)2 loading can boost the PEC performance of heterojunction and also acts as a protective layer that improves the stability of the Ni(OH)2/CdS/Zr:Fe2O3 electrode. Such enhanced PEC activity may be ascribed to the effective charge separation between CdS and Zr:Fe2O3 nanorods as well as increases the lifetime of holes due to Ni(OH)2. This work was supported by the BK21 plus program through the National Research Foundation (NRF). |
