[交流] Chem. Soc. Rev. 最新综述:软、硬模板结合控制合成介孔-大孔材料已有11人参与

有序介孔材料是上世纪90年代迅速兴起的新型纳米结构材料，它一诞生就得到国际物理学、化学与材料学界的高度重视，并迅速发展成为跨学科的研究热点之一。有序介孔材料虽然目前尚未获得大规模的工业化应用，但它所具有的孔道大小均匀、排列有序、孔径可在2－50nm范围内连续调节等特性，使其在分离提纯、生物材料、催化、新型组装材料等方面有着巨大的应用潜力。文章18页，引文60篇，值得一读。
文章题目：Carbon nanotube-based heterostructures for solar energy application Controlling macro- and mesostructures with hierarchical porosity through combined hard and soft templatings
文章摘要：Rigid, porous objects and surfactants serve as powerful templates for the formation of mesoporous and macroporous materials. When both types of template are combined in a single synthesis, materials with intricate architectures and hierarchical porosity can be obtained. In this tutorial review, we explain how to conduct syntheses with both soft and hard templates; moreover, we describe methods to control the final structure present in the templated material. Much of the foundation for multiple templating lies in the study of materials made with only one type of template. To establish a foundation in this area, a description of hard and soft templating is given, delving into the templates available and the steps required for effective templating. This leads into an extended discussion about materials templated with both hard and soft templates. Through the use of recent examples in the literature, we aim to show the diversity of structures possible through multiple templating and the advantages these structures can provide for a wide range of applications. An emphasis is placed on how various factors—such as the type of template, type of precursor, heat-treatment temperature, confinement within a small space, and template–template interactions-impact morphology.
