摘要: 以碳微球作为硬模板、纳米Silicalite-1分子筛作为壳层，采用水热法合成了Silicalite-1空心球材料。采用XRD、SEM、FT-IR、N2吸附、29Si MAS NMR、TG、XPS等技术对催化剂的物相、形貌和性能等进行表征，发现该空心材料具有较高的结晶度、发达的多级孔道结构和丰富的表面羟基。与传统方法制备的Silicalite-1分子筛催化剂相比，Silicalite-1空心材料在环己酮肟Beckmann重排反应中表现出优异的催化性能，使环己酮肟的转化率达99%、己内酰胺的选择性达94%，同时催化剂保持极佳的稳定性。研究表明，Silicalite-1空心材料中具有的大量巢式硅羟基和末端硅羟基是Beckmann重排反应的主要活性位，且可通过简单焙烧再生实现羟基活性位的完全恢复。
