Designing efficient semiconductor-based photocatalysts for hydrogen production is a challenging but promising prospect in energy conversion. Herein, a novel Z-scheme CdS/NH2-MIL-125(Ti) heterojunction is successfully fabricated through a facile solvethermal method. The detailed characterizations reveal that CdS nanoparticles are in-suit archored on NH2-MIL-125(Ti) nanoplates. Benefited from the intrinsic band alignment and intimate contact of two species, this established structure gives a positive effect regarding charge separation. In consequence, the optimal CdS/NH2-MIL-125(Ti) nanocomposites exhibit excellent photocatalytic performance with hydrogen evolution rate of 6.62mmol·h-1·g-1 under visible light illumination, which was 3.5 times higher than that of the pristine CdS. We believe that this work will provide a new avenue to develop high-efficiency heterojunction catalyst for solar-driven energy conversions and other application.

NH的结构2 -MIL-125(Ti)的/ CdS的Z-方案异质结的高效光催化ħ 2进化

设计用于生产氢的高效的基于半导体的光催化剂在能量转换中是具有挑战性但有希望的前景。本文中,通过一种简便的热解方法成功地制备了一种新型的Z-方案CdS / NH 2 -MIL-125(Ti)异质结。详细的特征表明,CdS纳米粒子适合在NH 2 -MIL-125(Ti)纳米板上进行射孔。得益于两个物种的固有能带对齐和紧密接触,这种确定的结构对电荷分离产生了积极影响。因此,最佳的CdS / NH 2 -MIL-125(Ti)纳米复合材料表现出优异的光催化性能,氢释放速率为6.62mmol·h -1 ·g -1在可见光照射下,是原始CdS的3.5倍。我们相信这项工作将为开发用于太阳能驱动的能量转换和其他应用的高效异质结催化剂提供一条新途径。
