【摘要】 作为胶体体系中最为常见的构建单元,纳米晶能够自发组装成周期性排列的超结构,又称"超晶体",是目前化学材料领域的一个前沿研究热点。为了实现纳米晶超晶体在不同领域特别是能源领域的应用价值,需要有效调控超晶体的组成、结构、界表面性质、介观形貌等。基于此,我们在传统溶剂挥发诱导组装的基础上相继发展了气液界面组装、团簇诱导组装、限域外延组装等组装技术,开发出了二维超晶体薄膜、一维链状超晶体、管状超晶体等,极大丰富了低维纳米晶超晶体的结构;此外,我们还提出了配体分子原位碳化策略发展了一系列碳包覆超晶体及其介孔石墨烯骨架衍生材料,进一步拓展了超晶体材料在能源领域中的应用。更多还原

【Abstract】 Nanocrystal(NC) supercrystals, self-assembled from colloidal NCs, represent an entirely new class of solidstate materials with unique collective properties arising from coupling interactions of the constituent NCs. In order to widen the range of applications for superlattice materials, it is desirable to precisely control their composition, structure, surface and interface properties, as well as mesoscopic morphologies. Over the past few years, we have put a considerable amount of efforts on the rational design of new functional materials by NC assembly, with a primary focus on energy-related applications. This talk will cover recent progress in our lab, ranging from the construction of low-dimensional supercrystals and their carbon-based derivatives to energy storage and conversion applications based on these well-defined superstructures.更多还原
