胶体晶体模板法是制备三维有序大孔材料的重要方法,其制备过程一般为:首先将单分散胶体微球组装成有序的胶体晶体形成模板;其次将前驱物填到模板间隙转化为固体骨架;最后去除模板得到相应3DOM材料。胶体晶体模板的制备、填充、去除是制备三维有序大孔材料的关键步骤,本文对此做了具体阐述并探讨了其中的几个影响因素,并论述3DOM材料的在催化、吸附领域的最新应用进展。
The colloidal crystal template method is an important method for preparing three-dimensional ordered macroporous materials. The preparation process is generally as follows: first, the monodisperse colloidal microspheres are assembled into an ordered colloidal crystal to form a template; secondly, the precursor is filled into the template gap to be converted into a solid Skeleton; Finally remove the template to get the corresponding 3DOM material. The preparation, filling and removal of colloidal crystal templates are the key steps in the preparation of three-dimensional ordered macroporous materials. This paper elaborates and discusses some of the influencing factors and discusses the newest 3DOM materials in the field of catalysis and adsorption Application progress.
