层状材料的催化作用

Catalysis by layered materials

层状材料是一类具有规则层状结构的化合物,由于其层板上骨架阳离子的可替代性和层间离子的可交换性使其在催化领域用途广泛,其层板结构为开发具有高表面积、可调节孔径和体积的新型纳米材料提供了可能。介绍了近年来层状材料(层状钙钛矿、柱撑黏土和水滑石)在酸碱催化、光催化、环保以及生物精制等方面的应用及其研究进展。

Layered materials, with regular lamellar structure and special structural properties, i. e. , substitutability of the framework cations on the layers and exchangeability of the interstitial ions between the layers, provide possibilities for development of new nanosized materials with high surface area and adjustable pore size and volume. Latest application of layered materials （layered perovskite, pillared clays, hydrotalcite） in acid-base catalysis, photocatalysis, environmental protection and bio-refining was reviewed in this article .
