Nano-/micro-interface or space-modulated catalytic reactions

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-/micro-interface 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.
