介晶(mesocrystal)是一类由纳米晶以结晶学有序的方式自组装而成的纳米粒子超结构,通常可以显示类单晶的电子衍射行为。介晶形成过程对经典结晶的挑战及其颗粒聚集体的独特结构特色具有的潜在应用促使人们对其广泛的研究。本文主要综述了介晶的制备方法、性能和应用研究的最新进展,其中合成方法主要包括共沉淀法、水热法、溶剂热法、拓扑转变法、电化学法和溶解再结晶方法,性能和应用方面主要介绍了介晶的催化性能、电化学性能、光电性能和生物医学应用。本文着重讨论了介晶的形成过程和介晶的结构-性能关系,指出了目前介晶的制备、性能和应用研究中存在的科学问题,并展望了其发展方向。
Mesocrystal is a type of nanostructured nanostructured nanostructured nanostructured nanostructures that are self-assembled in a crystallographic and orderly manner. The potential applications of mesogen formation to the challenges of classical crystallization and the unique structural features of the aggregates of particles have led to their extensive study. In this paper, the recent progress in the preparation, performance and application of mesogens are reviewed. The synthesis methods include coprecipitation, hydrothermal, solvothermal, topological transformation, electrochemical and recrystallization methods, Application mainly introduces the mesogenic catalytic properties, electrochemical properties, optoelectronic properties and biomedical applications. This paper focuses on the formation of mesogens and the structure-property relationship of mesogens. It also points out the current scientific problems in the preparation, properties and application of mesogens, and points out its development direction.
