摘　　要：固体颗粒稳定的Pickering乳液不仅具有高的动力学稳定性,而且其所创造的纳微界面和纳微空间直接影响到催化反应过程,为发展高效绿色的两相催化反应提供了变革性机会.其核心科学问题可归结为纳微界面/空间构建、纳微界面/空间反应区域控制与反应性能调控,并建立三者之间联系.因此,本文系统阐述了固体催化剂界面活性与催化反应性能的关联,重点分析了纳微界面/空间区域调控对催化反应性能的影响,总结并讨论了基于纳微界面/空间提出的Pickering乳滴固定床连续流动催化概念及其催化应用.最后,对纳微界面/空间调控催化反应所面临的挑战和科学机遇进行了展望.The solid particle-stabilized Pickering emulsion not only exhibits high kinetic stability,but also creates the nano-/micro-interfaces or spaces that directly affect the catalytic reaction process,providing a transformative opportunity for the development of efficient green two-phase catalytic reactions.However,the current understanding of the key scientific problems is required to be solved in the field of catalysis,such as nano-/micro-interface or space construction,nano-/micro-interface or space reaction region control and reaction performance regulation,and the relationship between the three.Therefore,this paper presents a systematic description of the correlation between interfacial activity and catalytic performance of solid catalysts,focuses on analyzing the influence of nano-/microinterface or space regulation on catalytic performance,summarizes and discusses the concept of Pickering emulsion droplet immobilization based on the nano-/micro-interfaces or spaces of bed continuous flow catalysis and its catalytic applications.Finally,the challenges and scientific opportunities for nano-/micro-interface/space-controlled catalytic reactions are discussed.
