Supported metal nanoparticles are widely used as catalysts in the industrial production of chemicals, but still suffer from deactivation because of metal leaching and sintering at high temperature. In recent years, serious efforts have been devoted to developing new strategies for stabilizing metal nanoparticles. Recent developments for preparing sinter-resistant metal-nanoparticle catalysts via strong metal-support interactions, encapsulation with oxide or carbon layers and within mesoporous materials, and fixation in zeolite crystals, are briefly summarized. Furthermore, the current challenges and future perspectives for the preparation of highly efficient and extraordinarily stable metal-nanoparticle-based catalysts, and suggestions regarding the mechanisms involved in sinter resistance, are proposed.
负载型金属纳米粒子作为催化剂被广泛应用于化工产品的工业生产中，但仍存在金属浸出和高温烧结导致的失活问题。近年来，人们致力于开发新的策略来稳定金属纳米粒子。本文简要综述了通过强金属-载体相互作用、氧化物或碳层包覆以及介孔材料内负载、沸石晶体固定等方法来制备抗烧结金属纳米粒子催化剂的最新进展。此外，还提出了制备高效、超稳定的基于金属纳米粒子的催化剂所面临的挑战和未来展望，并对抗烧结机制提出了建议。
