一个多世纪以来，金属介导的化学反应一直是一个重要的研究领域。近年来，人们越来越多地致力于通过优化活性催化剂的结构和化学环境来提高金属介导催化的性能，以实现过程的强化和可持续性。网络支撑催化剂使用固体（刚性或柔性）支撑，嵌入金属催化剂，理想情况下允许有效的前驱体进入催化位点，同时在反应后不需要催化剂分离步骤，催化剂浸出最少。本文综述了网络负载催化剂的最新进展，以提高各种金属催化反应的性能。我们详细讨论了在金属催化剂载体上实现均相催化和多相催化综合效益的不同策略。我们概述了这种混合催化剂在间歇和连续流配置中的独特的多功能性、可调性、性质和活性。此外，我们提出了潜在的未来方向，以解决当前柔性网络支持催化剂的一些挑战和缺点。
Metal-mediated chemical reactions have been a vital area of research for over a century. Recently, there has been increasing effort to improve the performance of metal-mediated catalysis by optimizing the structure and chemical environment of active catalytic species towards process intensification and sustainability. Network-supported catalysts use a solid (rigid or flexible) support with embedded metal catalysts, ideally allowing for efficient precursor access to the catalytic sites and simultaneously not requiring a catalyst separation step following the reaction with minimal catalyst leaching. This minireview focuses on recent developments of network-supported catalysts to improve the performance of a wide range of metal-mediated catalytic reactions. We discuss in detail the different strategies to realize the combined benefits of homogeneous and heterogeneous catalysis in a metal catalyst support. We outline the unique versatility, tunability, properties, and activity of such hybrid catalysts in batch and continuous flow configurations. Furthermore, we present potential future directions to address some of the challenges and shortcomings of current flexible network-supported catalysts.
