Fabricating heterostructures enhances the photocatalytic performance of metal-organic frameworks (MOFs) due to their excellent light absorption and high efficient charge transfer capacity. In this study, we designed and implemented three-dimensional dendritic UiO-66-NH2@MIL-101(Fe) (UOML) heterostructures as catalysts for photocatalytic styrene oxidation. The UOML catalysts exhibited a well-matched band gap structure and efficient catalytic interface, leading to a remarkable photoexcited carrier separation and catalytic activity. Our results present a promising insight for synthesizing novel MOFs-based catalysts and their applications.
制备异质结构可增强金属有机框架材料（MOFs）的光催化性能，这归因于它们出色的光吸收能力和高效的电荷转移能力。在本研究中，我们设计并制备了三维树枝状UiO-66-NH2@MIL-101(Fe)（UOML）异质结构作为光催化苯乙烯氧化的催化剂。UOML催化剂表现出匹配良好的带隙结构和高效的催化界面，导致光激发载流子显著分离并具有催化活性。我们的结果为合成新型MOF基催化剂及其应用提供了有前景的见解。
