| 英文摘要 | Cadmium sulfide (CdS), is one of the superior visible-light driven photocatalysts, and has a prosperous and practical future in hydrogen (H-2) production from water splitting for addressing environmental problems, such as environmental contamination and energy shortage. But the inherent serious drawback of photocorrision always limits its photocatalytic performance. Here, we fabricated a layered nanojunction to enhance the H-2 generation of the surface-fluorinated TiO2/CdS-diethylenetriamine (F-TiO2/CdS-DETA) system. The loading of F-TiO2 nanosheets (NSs) with exposed {001} facets on inorganic-organic CdS-DETA nanobelts (NBs) greatly improves the interfacial contact. The layered nanojunction structure efficiently inhibits the charge carriers' recombination and enhances the H-2 production stability of CdS. At an optimal ratio of 30%F-TiO2, the F-TiO2/CdS-DETA composite exhibits the highest H-2 production rate of 8342.86 mu mol h(-1) g(-1), which is 6.6 times and 1.7 times as high as that of CdS nanoparticles and CdS-DETA NBs, respectively. The apparent quantum yield of the H-2 evolution system reaches 24.9% at 420 nm with a Pt cocatalyst. More importantly, the surface of the F-TiO2 nanosheets enriches a large amount of trapping centers of photogenerated holes, which can thus efficiently promote the charge carriers' separation and enhance the photocatalytic H-2 evolution of CdS-DETA. Also, the effective charges transfer route of F-TiO2/CdS-DETA is also demonstrated by a photoluminescence test and photocurrent response. This work provides an ideal model for the design of stable and efficient H-2 production photocatalysts. |
