With the recent advances in nanoscience and nanotechnology, more and more nanoparticle catalysts featuring high accessibility of active sites and high surface area have been explored for their use in various chemical transformations, and their rise in popularity among the catalysis community has been unprecedented. The industrial applications of these newly discovered catalysts, however, are hampered because the existing methods for separation and recycling, such as filtration and centrifugation, are generally unsuccessful. These limitations have prompted development of new methods that facilitate separation and recycling of nanoparticle catalysts, so as to meet the burgeoning demands of green and sustainable chemistry. Recently, we have found that Pickering-emulsion inversion is an appealing strategy with which to realize in situ separation and recycling of nanoparticle catalysts and thereby to establish sustainable catalytic processes. We feel that at such an early stage, this strategy, as an alternative to conventional methods, is conceptually new for readers but that it has potential to become a popular method for green catalysis. This Concept article aims to provide a timely link between previous efforts and both current and future research on nanoparticle catalysts, and is expected to facilitate further investigation into this strategy.
随着纳米科学和纳米技术的最新进展，越来越多具有高活性位点可及性和高表面积的纳米颗粒催化剂被探索用于各种化学转化，并且它们在催化领域的受欢迎程度空前提高。然而，这些新发现催化剂的工业应用受到阻碍，因为现有的分离和回收方法，如过滤和离心，通常并不成功。这些限制促使人们开发新方法，以促进纳米颗粒催化剂的分离和回收，从而满足绿色和可持续化学不断增长的需求。最近，我们发现皮克林乳液反转是一种有吸引力的策略，可用于实现纳米颗粒催化剂的原位分离和回收，从而建立可持续的催化过程。我们认为，在这样一个早期阶段，作为传统方法的替代方案，该策略对读者来说在概念上是新颖的，但它有可能成为绿色催化的一种流行方法。这篇概念文章旨在为之前关于纳米颗粒催化剂的研究与当前及未来研究之间提供及时的联系，并有望促进对该策略的进一步研究。
