英文摘要： Yolk-shell nanostructures have been paid numerious attention for their excellent performance and important applications in the fields of energy, catalysis and so on. This project aims at further designing and synthesizing yolk-shell nanostructured cataltysts based on our previous work. In this project, we will develop some new facile and controllable routes to fabricate metallic, semiconductor and hybrid yolk-shell nanostructures, and modify this nanostructures to optimize the catalytic performance according to the need. Besides, we will also deeply explore the catalytic mechanism of the yolk-shell nanostructures to guide the further design and synthesis of this kind of nanostructured catalysts. Therefore, this project will supply several new controllable methods to prepare yolk-shell nanostructures and some yolk-shell nanostructured materials with highly catalytic performance and controllable fuctions. In addiiton, we can bring some new chances for the fields of energy, organic catalysis and so forth, such as using the much cheaper reagent chlorobenzene for Heck/Suzuki carbon coupling reactions instead of iodobenzene, resolving the CO-tolerance of electrocatalysts for the direct alcohol fuel cells, and the separation of catalysts etc. Moreover, this project can help us understand the catalytic performance in na
