多相催化无疑是现代化学工业的关键技术。如今，大多数化学生产过程都是由固体催化剂催化的。因此，世界各地的研究人员尝试改进现有催化剂或开发全新催化剂也就不足为奇了。固体催化剂的性能取决于其组成，但在很大程度上也取决于形态特性。因此，颗粒形状和孔拓扑的控制是高性能催化剂的关键因素。近年来报道了许多有趣的方法，本文试图总结其中的一些方法。材料和制备程序的选择并不全面，但代表了一系列非常有趣的方法，包括自下而上的方法以及合成后修饰。
Heterogeneous Catalysis is undoubtedly a key technology in modern chemical industry. Nowadays, most processes in chemical production are catalyzed by solid catalysts. It is thus not surprising that researchers worldwide try to improve existing catalysts or to develop completely new ones. The performance of solid catalysts is determined by their composition but to a great extent also by morphological properties. Control of particle shape and pore topology are thus crucial factors for high performance catalysts. Many interesting approaches have been reported in recent years and the present contribution tries to summarize some of them. The choice of materials and preparation procedures is not comprehensive by a long way, but represents a selection of highly interesting approaches, including bottom‐up approaches as well as post‐synthesis modifications.
