摘　　要：Halide perovskite nanocrystals are potential catalysts for CO_(2) photoreduction,while,the strong radiative recombination and insufficient stability limit their catalytic performance and application.Herein,we report that layered double hydroxide nanosheets activate CsPbBr_(3) nanocrystals(CLDH)for enhanced photocatalytic CO_(2) reduction.These CLDH heterojunctions show the remarkably enhanced CO_(2) photoreduction performance;without cocatalyst and sacrificial agent,the average electron consumption rate of CLDH(49.16μmol·g^(−1)·h^(−1))is approximately 3.7 times higher than that of pristine CsPbBr_(3).Also,CLDH catalyst exhibits a robust stability after ten cycles over 30 h.
