具有明确晶体结构的异金属稀土过渡金属(4f-3d)簇合物集成了多个金属中心，为实现协同催化效应提供了平台。在这里，我们提出了一种通过将原子上精确的4f-3d团簇Ln(52)Ni(56)加载到CDS光吸收表面来增强氢析出的策略。有趣的是，团簇Ln(52)Ni(56)中的部分Ni2+离子被Cd~(2+)交换形成了Ln(52)Ni(56-x)Cd(X)/CDS复合材料。光催化研究表明，在25353 molh(-1)g(-1)处，Cd S向Eu52Ni56-xCdx团簇的高效协同多路径电荷分离和转移使高可见光驱动的氢析出成为可能。这项工作为在半导体材料上组装异金属4f-3d团簇来设计高活性的光催化析氢催化剂提供了策略。
Heterometallic lanthanide-transition-metal (4f-3d) clusters with well-defined crystal structures integrate multiple metal centers and provide a platform for achieving synergistic catalytic effects. Herein, we present a strategy for enhanced hydrogen evolution by loading atomically precise 4f-3d clusters Ln(52)Ni(56) on a CdS photoabsorber surface. Interestingly, some Ni2+ ions in the clusters Ln(52)Ni(56) were exchanged by the Cd2+ to form Ln(52)Ni(56-x)Cd(x)/CdS composites. Photocatalytic studies show that the efficient synergistic multipath charge separation and transfer from CdS to the Eu52Ni56-xCdx cluster enable high visible-light-driven hydrogen evolution at 25353molh(-1)g(-1). This work provides the strategy to design highly active photocatalytic hydrogen evolution catalysts by assembling heterometallic 4f-3d clusters on semiconductor materials.
