英文摘要： Hierarchical micro-/nanostructures with unique microscopic structures and levels exhibited considerably novel functions and enhanced effect due to their substantial intrinsic effect, nanoscaled effect and associative effect, and displayed a promising application prospect.In this project,we will focus on the controllable synthesis of bismuth-related hierarchical nanostructures firstly. On the basis of liquid phase reaction, different bismuth-related hierarchical micro-/nanostructures will be synthesized by varying reaction systems, reaction mode and reaction conditions. The formation mechanism and assembling process of the hierarchical nanostructurs under various conditions will be also discussed. Further investigation will be focused on the structure-property relationship between hierarchical structure and catalytic and adsorptive properties, so as to direct the structural design of hierarchical bismuth-related materials. Eventually, the regulation and control in spatial and dynamic process of hierarchically structural assembling will be achieved. The large-scale synthesis of bismuth-related hierarchical micro-/nanostructures with novel structure, uniform morphology and size, and excellent catalytic and adsorptive properties will be also realized. This project is not limited to the investigation of fabrication or application of hierarchical nanostructures, but covers three levels of materials research ranging from material design, structure-property relationship to controllable synthesis. Through the spiral-like ascending procedure containing material design, material synthesis and application, structure-property analysis, regulation and control of hierarchical structures assembling, structure and function optimization, the large-scale manufacturing and application of bismuth-related hierarchical structures with novel structure and superior properties could be achieved. This project will extend the range and depth of the studies of bismuth-related materials.
