Abstract: Single-atom catalysts(SACs) have attracted much attention for their superior catalytic performance in various fields. It has been widely accepted that the selection of appropriate substrates is crucial to the fabrication and application of SACs. Layered double hydroxides(LDHs) have been developed as one of the promising substrates for single-atoms due to their unique adjustable supramolecular structures. In this review, we comprehensively sort out the research of SACs based on LDHs. By analyzing the characteristics of LDHs and the single-atoms, respectively, the preparation strategies of SACs by using LDHs are summarized. Their applications as efficient catalysts in electrocatalysis, photocatalysis and thermal catalysis are then discussed. Finally, we summarize the opportunities and challenges for the rational design and application expansion of SACs based on LDHs in the future.

Key words: Layered double hydroxide, Single-atom catalyst, Synthesis, Catalysis
