报告题目：纳米结构催化剂的设计和性能研究
摘要：纳米结构材料具有纳米尺度的结构单元和微米以上尺度的分级多孔结构。这些材料中的纳米结构单元带来了高比表面，丰富的表面官能团；而分级多孔结构提供了易于操作的机械性能，例如较好的强度，容易回收等，可望成为理想的多相催化剂。在催化研究中，我们针对纳米贵金属颗粒的分散度和稳定性、反应物种的定向扩散、反应体系的均匀混合等三个催化中的关键因素，设计了原位还原和核壳结构制备高分散高稳定性纳米结构催化剂、界面调控提高选择性、多级孔道结构实现择型催化、纳米磁子实现微滴内搅拌、浸润性梯度等新颖手段完成高效催化催化材料，表现出很好的催化性能，并应用在生物医药和香料等产业中的选择性加氢反应，生产高价值化学品。

报告题目：Metal-Organic Framwork NanoComposite Materials
摘要：Metal-organic frameworks (MOFs) have crystalline structures and are typically characterized by large internal surface areas, uniform but tunable cavities, and tailorable chemistry. MOFs have shown great promise for a variety of applications, including gas storage, chemical separation, catalysis and sensing. Particularly, the incorporation of functional materials, such as nanoparticles, small molecules, or even biomaterials, in MOFs has attracted great attention because of the benefits of the novel chemical and physical properties exhibited by certain classes of functional materials. In our group, we developed a serious of encapsulation strategies that allow many types of functional materials to be fully incorporated within crystals in a well-dispersed fashion. Our strategy relies on the successive adsorption of nanoparticles onto the continuously forming surfaces of the growing MOF crystals. The as-prepared hybrid materials exhibit both active (catalytic, magnetic, and optical) properties deriving from the incorporated functional materials and size- and alignment-selective behavior (i.e., molecular sieving and regioselective guest reactivity) originating from the well-defined microporous nature of the MOF component.
