Catalysts are important to the chemical industry and environmental remediation due to their effective conversion of one chemical into another. Among them, composite catalysts have attracted continuous attention during the past decades. Nowadays, composite catalysts are being used more and more to meet the practical catalytic performance requirements in the chemical industry of high activity, high selectivity and good stability. In this paper, we reviewed our recent work on development of composite catalysts, mainly focusing on the composite catalysts obtained from porous materials such as zeolites, mesoporous materials, carbon nanotubes (CNT), etc. Six types of porous composite catalysts are discussed, including amorphous oxide modified zeolite composite catalysts, zeolite composites prepared by co-crystallization or overgrowth, hierarchical porous catalysts, host-guest porous composites, inorganic and organic mesoporous composite catalysts, and polymer/CNT composite catalysts.
由于催化剂能有效地将一种化学物质转化为另一种化学物质，因此对化学工业和环境修复非常重要。其中，复合催化剂在过去几十年中一直受到持续关注。如今，为了满足化学工业中高活性、高选择性和良好稳定性等实际催化性能要求，复合催化剂的应用越来越广泛。在本文中，我们回顾了我们最近在复合催化剂开发方面的工作，主要集中在由沸石、介孔材料、碳纳米管（CNT）等多孔材料制备的复合催化剂上。讨论了六种类型的多孔复合催化剂，包括非晶态氧化物改性沸石复合催化剂、通过共结晶或过度生长制备的沸石复合材料、分级多孔催化剂、主客体多孔复合材料、无机和有机介孔复合催化剂以及聚合物/碳纳米管复合催化剂。
