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 Ni on a CdS photoabsorber surface. Interestingly, some Ni ions in the clusters Ln Ni were exchanged by the Cd to form Ln Ni Cd /CdS composites. Photocatalytic studies show that the efficient synergistic multipath charge separation and transfer from CdS to the Eu Ni Cd cluster enable high visible-light-driven hydrogen evolution at 25 353 μmol h g . This work provides the strategy to design highly active photocatalytic hydrogen evolution catalysts by assembling heterometallic 4f-3d clusters on semiconductor materials.
具有明确晶体结构的异金属镧系元素-过渡金属（4f-3d）簇整合了多个金属中心，并为实现协同催化效应提供了一个平台。在此，我们提出了一种通过将原子精确的4f-3d簇LnNi负载在CdS光吸收剂表面来增强析氢的策略。有趣的是，簇LnNi中的一些Ni离子被Cd交换，形成了LnNiCd/CdS复合材料。光催化研究表明，从CdS到EuNiCd簇的高效协同多路径电荷分离和转移使得在25 353 μmol h g的条件下能够实现高可见光驱动的析氢。这项工作提供了通过在半导体材料上组装异金属4f-3d簇来设计高活性光催化析氢催化剂的策略。
