摘要
经过长期进化,生物质已经形成了复杂的分级胞状结构。这些结构为生物体生长和发育提供了传输水分和营养物质的快速通道。由生物质转化形成的高性能材料,不仅保持了材料本身的优良性质,而且还具有生物质的宏观形貌和微观结构特征。由于具有丰富的分级多孔结构和优良的机械性能,生物形态材料在催化、分离与吸附和高温尾气处理等领域具有广泛的应用前景。目前,各种不同类型的生物质已被广泛用来制备生物形态的高性能材料。本文结合国内外研究进展综述了生物形态材料的制备技术、材料种类以及应用情况。
Biomass exhibits complex hierarchical cellular structures due to the long-term evolution and development. These structures provide quick and effective passages for the transport of water and nutrition in the growth of living beings. Biomorphic high-performance materials converted from biomass possess not only excellent mechanical properties from themselves but also morphological and microstructural features similar to their source biomass. Due to the hierarchical porous structures with pore size ranging from nanometer to micrometer scale, these materials have potential applications in many fields such as heterogeneous catalysis, adsorption/separation, exhaust gas treatment and so on. Nowadays, different kinds of biomass have been employed to prepare biomorphic high-performance materials. The review introduces the recent progress in the preparations and applications of biomorphic materials.
