摘　　要：Developing photocatalyst with high activity,superior stability and prominent selectivity for CO_(2)conversion is of great importance for the target of carbon neutralization.Herein,3 D dahlia-like NiAl-LDH/CdS heterosystem is developed through in-situ decoration of exfoliated CdS nanosheets on the scaffold of NiAl-LDH and the on-spot self-assembly.The formation of a hierarchical architecture collaborating with well-defined 2 D/2 D interfacial interaction is constructed by optimizing the ratio of CdS integrated in the formation of the heterojunction.The light-harvesting capacity of NiAl-LDH/CdS is improved by this unique scaffold,and the charge transfer between NiAl-LDH and CdS is effectively facilitated by virtue of the unique 2 D/2 D interface.As a result,the 3 D hierarchical NiAl-LDH/CdS heterosystem presents 12.45μmol g^(-1)h^(-1)of CO production(3.3 and 1.6 folds of pristine NiAl-LDH and CdS) with 96% selectivity and superior stability.This 3 D hierarchical design collaborating with 2 D/2 D interfacial interaction provides a new avenue to develop ideal catalysts for artificial photosynthesis.
