| 제목 | Fast charge transport at the interface of core–shell structured Au@CdS and densely packed TiO2 nanofibers for visible light-induced H2 production |
| 초록 | Photocatalytic H2 generation has attracted significant attention because of its great potential for low-cost and clean H2 production. here, we prepared a core–shell structured Au@CdS on TiO2 nanofibers (Au@CdS/TNF) for H2 production under visible (λ ＞ 420 nm) irradiation. The relative comparison of Au-deposited CdS/TNF (Au/CdS/TNF) and P25 revealed that the H2 production on Au@CdS/TNF was significantly enhanced than Au@CdS/P25. These results can be attributed to the synergistic effect of the core–shell structured Au@CdS and the compact structure of TNF. The core–shell structured Au@CdS may inhibit the formation of CdSO4 from CdS and the Au core could transfer electrons from CdS to TiO2 without any screening effect for light absorption by CdS. Moreover, interparticle electron transfer is more favorable for TNF than P25 due to the well-aligned TNF framework. Reference: S.-I In et al. Appl. Catal. B Environ, 166 (2015): 423-431. |
