Low-dimensional metal-organic frameworks (LD MOFs) have attracted increasing attention in recent years. Their unique properties, including ultrathin structures, fully exposed active sites, and tunable compositions make them excellent catalysts for CO₂ catalytic reduction. Even though numerous efforts have been attempted to modify the morphologies of LD MOFs, it is still highly important to explore the synthetic principles and catalytic properties of LD MOFs. In this review, various synthetic methods for preparing LD MOFs are summarized. The unique properties and applications of LD MOFs in CO₂ catalytic reduction reaction are introduced and discussed. Finally, several challenges and prospects of this emerging research field are proposed. The present review could provide a comprehensive understanding on the design and synthesis of LD MOFs for CO₂ reduction.
