分级ZIF衍生碳/Bi12O17Cl2异质结构协同调控电子动力学与光学性能,提升纯水体系中CO2光还原性能
Hierarchical ZIF-derived carbon/Bi12O17Cl2 heterostructures synergistically enhance electron dynamics and optical properties to boost CO2 photoreduction in pure water
摘要
Abstract
Conventional Bi12O17Cl2 photocatalyst suffer from narrow solar harvesting,weak CO2 adsorption and poor charge utilization.Herein,an intimate hierarchical heterojunction was constructed by embedding Bi12O17Cl2 ultrathin nanotubes into hierarchical Co-ZIF-derived porous carbon(Co-PC/BOC).Multi-cavity reflection within Co-PC nanocages and localized surface plasmon resonance of in situ generated Co3O4 domains synergistically enhance the light harvest ability of the Co-PC/BOC in the full spectral range.In pure water without any photosensitizers or sacrificial agents,the optimal composite exhibits a CO yield of 34.16 μmol g−1 h−1 with 100%selectivity,2.9-fold higher than bare BOC.In situ DRIFTS and photo/electrochemical characterizations demonstrate that Co-PC serves as a dual-function platform of plasmonic hot-electron injector and charge separation hub,whereas BOC provide abundant surface sites for *COOH formation and *CO cleavage.Our work highlights the promising potential of metal-organic frameworks and their derivatives in developing efficient artificial photosynthesis systems.关键词
