近年来，Pickering乳液因其易于制备和强稳定性的特点引起了人们的广泛关注。与经典乳液不同，在Pickering乳液中，位于液体界面处的固体微粒或纳米颗粒被用作稳定剂，而不是表面活性剂，从而增加了液滴的寿命。此外，与由表面活性剂稳固的乳液相比，Pickering乳液具有更高的稳定性、更低的毒性和刺激反应性。因此，它们可以被认为是具有广泛用途的理想成分，如光催化和新材料的制备。此外，纳米颗粒的形貌对Pickering乳液的稳定性及其潜在利用率有很大的影响。在本文中，我们回顾了近年来关于Pickering乳液的一些研究成果，重点介绍了纳米颗粒的形态，如立方体、椭球体、纳米片、球体、圆柱体、棒状、花生状，如何影响这种乳液的类型和稳定性，以及它们在抗菌活性、蛋白质识别、催化、光催化和水净化等不同领域的应用。

In recent years, Pickering emulsions and their applications have attracted a great deal of attention due to their special features, which include easy preparation and enhanced stability. In contrast to classical emulsions, in Pickering emulsions, solid microparticles or nanoparticles that localize at the interface between liquids are used as stabilizers, instead of surfactants, to enhance the droplet lifetime. Furthermore, Pickering emulsions show higher stability, lower toxicity, and stimuli-responsiveness, compared with emulsions that are stabilized by surfactants. Therefore, they can be considered attractive components for various uses, such as photocatalysis and the preparation of new materials. Moreover, the nanoparticle morphology strongly influences Pickering emulsion stability as well as the potential utilization of such emulsions. Here, we review recent findings concerning Pickering emulsions, with a particular focus on how the nanoparticles morphology (i.e., cube, ellipsoid, nanosheet, sphere, cylinder, rod, peanut) influences the type and stability of such emulsions, and their current applications in different fields such as antibacterial activity, protein recognition, catalysis, photocatalysis, and water purification.
