我们设计并成功制备了一种以Zn 1-xCdxS为介导界面的ZnS/CdS三维介孔异质结构。我们首次设计并成功制备了一种具有介导Zn 1-xCdxS界面的ZnS/CdS三维介孔异质结构，该界面可作为载流子传输通道。的H2-生产率和稳定性的异质结构，涉及两个硫化物显着，同时提高了通过一个简单的后退火方法的界面状态的仔细修改。在最佳工艺条件下制备的CdS样品在可见光下的产氢速率为106.5 mmol h-1 g-1，是以乙二胺和去离子水为溶剂制备的CdS的152倍和966倍。该优异的H2-产生速率对应于CdS基光催化剂中的最高值。此外，该异质结构显示出良好的光催化稳定性超过60小时。
We designed and successfully fabricated a ZnS/CdS 3D mesoporous heterostructure with a mediating Zn1–xCdxS interface. We designed and successfully fabricated a ZnS/CdS 3D mesoporous heterostructure with a mediating Zn1–xCdxS interface that serves as a charge carrier transport channel for the first time. The H2-production rate and the stability of the heterostructure involving two sulfides were dramatically and simultaneously improved by the careful modification of the interface state via a simple post-annealing method. The sample prepared with the optimal parameters exhibited an excellent H2-production rate of 106.5 mmol h–1 g–1 under visible light, which was 152 and 966 times higher than CdS prepared using ethylenediamine and deionized water as the solvent, respectively. This excellent H2-production rate corresponded to the highest value among the CdS-based photocatalysts. Moreover, this heterostructure showed excellent photocatalytic stability over 60 h.
