具有多孔分级微/纳米结构的工程半导体是获得高太阳光利用效率和强光催化性能的可行策略。在这项工作中，溶剂蒸发和形貌继承退火的铁基金属有机框架的集成策略，以制备多级尖晶石铁酸锌（ZnFe 2 O 4）微/纳米结构。分级ZnFe 2 O 4结构的形貌和孔隙率可以通过优化退火温度来调节。利用磁分离性能，将这些高度可见光响应的分级ZnFe 2 O 4微/纳米结构材料作为多功能光催化材料，分析了它们的光催化活性和重现性，并探讨了光催化机理。这项工作提供了一个可控的和通用的路线，构建新的分层半导体与特定的组成和有趣的结构。
Engineering semiconductors with porous hierarchical micro-/nanostructures is a feasible strategy to obtain high solar-light utilization efficiency and strong photocatalytic performance. In this work, an integrated strategy of solvent evaporation and morphology-inherited annealing for the Fe-based metal-organic framework was developed to prepare the hierarchical spinel zinc ferrite (ZnFe2O4) micro-/nanostructure. The morphology and porosity of the hierarchical ZnFe2O4 structures can be adjusted by optimizing the annealing temperatures. Benefitting from magnetic separation performance, these highly visible light-responsive hierarchical ZnFe2O4 micro-/nanostructures are demonstrated to be multifunctional photocatalytic materials, and their photocatalytic activity and reproducibility were analyzed, and the photocatalytic mechanism was also investigated. This work provides a controlled and generic route for constructing novel hierarchical semiconductors with specific compositions and intriguing structures.
