摘要：

Catalysts play vital roles in energy and chemical industries. Precise design and regulation of catalysts' structure could improve their catalytic performance. Atomic layer deposition (ALD) is a gas-solid reaction technique that follows the saturated self-limiting theory, which has been regarded as one of the most efficient methods in tuning the composition, size and location of the active phases. In this review, we present a comprehensive summary of ALD in regulating the sizes and the surface/interface of activity phases, and the design of multi-functional core-shell structural and porous materials. The advantages of ALD enable the effective regulations of the catalyst's activity, selectivity and stability. However, the mechanism of ALD for the supports with complex structure has not been studied systematically, which should be the key point in the following researches. Moreover, to design well-organized and versatile catalysts to improve the catalytic activity and to acquire the reaction mechanism are also the research directions in the future. © 2021, Chemical Industry Press Co., Ltd.
