【摘要】：以大孔和超大孔为主的多孔材料因其独特的结构特性在催化、分离、能源、生物医学等领域具有重要的应用价值,但是其在孔结构的控制上仍然存在较大挑战,冰凝诱导法由于操作简单、孔结构容易调控而成为制备多孔材料的重要方法之一。本文从冰凝诱导法制备多孔材料的原理出发,对冰凝诱导制备多孔材料及结构调控、潜在应用、存在问题和展望几个方面进行评述,重点介绍了通过原料组成及浓度、颗粒尺寸、冷冻温度、冷冻速率、溶液环境等手段对孔尺寸及壁厚、孔方向、孔形态的调控,并指出冰凝诱导与其他方法相结合以及进一步功能化是其未来发展的主要方向。
[Abstract]:Macroporous and super-porous materials have important application value in catalysis, separation, energy, biomedicine and other fields because of their unique structural characteristics, but there are still great challenges in the control of pore structure. Ice coagulation induction method is one of the most important methods for the preparation of porous materials due to its simple operation and easy control of pore structure. Based on the principle of the preparation of porous materials by ice coagulation induction, this paper reviews the preparation of porous materials by ice coagulation induction, its potential application, existing problems and prospects, with emphasis on the composition and concentration of raw materials. Particle size, freezing temperature, freezing rate, solution environment, etc., regulate the pore size and wall thickness, pore direction and pore morphology. It is pointed out that the combination of ice coagulation induction and other methods and further functionalization are the main directions of its future development.
