Noble metal nanocrystals have been widely used as active components in catalysis and chemical/bio-sensing. The sizes, structures, and shapes of noble metal nanocrystals are crucial to their electronic, optical, and catalytic properties. However, metal nanocrystals tend to lose their structural and morphological properties when they are subjected to thermal and chemical treatment. Therefore, stabilization of noble metal nanostructures remains a challenge. In this feature article, we present our recent efforts on the stabilization of noble metal nanocrystals, i.e., using inorganic and non-metal solids as supports and physical barriers, protecting the nanocrystal surface by a metal coating, and forming alloys with other metals. At the end of this review, we provide our perspectives on the future development of effective methods for nanocrystal stabilization.

稳定的贵金属纳米结构，用于催化和传感

贵金属纳米晶体已被广泛用作催化和化学/生物传感中的活性成分。贵金属纳米晶体的尺寸，结构和形状对其电子，光学和催化性能至关重要。然而，当金属纳米晶体经受热处理和化学处理时，往往会失去其结构和形态特性。因此，贵金属纳米结构的稳定化仍然是一个挑战。在这篇专题文章中，我们介绍了我们最近在稳定贵金属纳米晶体方面所做的努力，即使用无机和非金属固体作为载体和物理屏障，通过金属涂层保护纳米晶体表面，并与其他金属形成合金。在这篇评论的结尾，我们提供了有关纳米晶体稳定有效方法的未来发展的观点。
