FeCo合金多面体微/纳米结构的设计、合成及其在对硝基苯酚还原中的应用

In recent years, FeCo alloys or intermetallic compounds micro-/nanomaterials have been paid numerous attentions because of their excellent properties and applications in the fields of magnetic fluids, biotechnology/biomedicine, magnetic resonance imaging, data storage, environmental remediation, catalysis, and so on. This project aims at further designing and synthesizing of a series of polyhedron-like FeCo alloy micro-/nanostructures based on our preliminary works. Here, we will develop some new simple and controllable routes to prepare polyhedron-like FeCo alloy micro-/nanostructures. Especially, we will also deeply explore the catalytic mechanism of the polyhedron-like FeCo alloy micro-/nanostructures to guide the further design a synthesis of this kind micro-/nanostructures and some of them with high catalytic activity and stability. Therefore, this project will supply several new controllable processes to obtain polyhedron-like FeCo alloy micro-/nanostructures and some of them with highly catalytic performance and controllable functions. Furthermore, we can bring some new changes for the organic catalysis, such as p-nitrophenol reduction. This project can help us understand the catalytic performance in micro-/nanoscale from atomic/molecular scale. In a word, this project is very important in both of the theoretical research and practical applications.
