Integration of Lanthanide–Transition-Metal Clusters onto CdS Surfaces for Photocatalytic Hydrogen Evolution

摘要: 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 strategy enhanced hydrogen evolution by loading atomically precise 4f-3d Ln52 Ni56 on CdS photoabsorber surface. Interestingly, some Ni2+ ions in the were exchanged Cd2+ to form Ni56-x Cdx /CdS composites. Photocatalytic studies show that efficient multipath charge separation transfer from Eu52 cluster enable high visible-light-driven at 25 353 μmol h-1  g-1 . This work provides design highly active photocatalytic catalysts assembling heterometallic semiconductor materials.
