Particle-stabilised or Pickering emulsions are versatile systems. In the past 10 years a new application has emerged in the field of catalysis to use them as vehicles to carry out catalytic reactions, allowing a more environmentally friendly process with high conversions and selectivities and important advantages for catalyst recovery. As the area has advanced rapidly, the intention of this review is to summarize the latest innovations being reported. An overview is given regarding the kinds of liquid phases comprising the emulsion system, the different types of solid particle stabilizers (whether they contain catalyst or not) and the catalytic reactions studied. A section describing methods for recovering the catalyst is also included, in which various stimuli are discussed. Finally, the importance of using Pickering emulsions to carry out reactions in flow and in multi-step cascade systems is highlighted with various examples to support the benefits of transferring this technology to industrial processes.
颗粒稳定乳液或皮克林乳液是多功能体系。在过去十年中，催化领域出现了一种新应用，即将它们用作进行催化反应的载体，从而实现更环保的过程，具有高转化率和选择性，并且在催化剂回收方面具有重要优势。随着该领域的迅速发展，本综述旨在总结所报道的最新创新成果。概述了构成乳液体系的液相种类、不同类型的固体颗粒稳定剂（无论是否含有催化剂）以及所研究的催化反应。还包括一个描述催化剂回收方法的部分，其中讨论了各种刺激因素。最后，通过各种实例强调了在流动体系和多步级联体系中使用皮克林乳液进行反应的重要性，以支持将该技术应用于工业过程的益处。
