Engineering Asymmetric MOF Composites toward High-Efficiency Catalytic Reactions

Asymmetric metal-organic framework composites (AMOFs) have garnered increasing attention due to their distinctive functional properties, demonstrating considerable promise in catalysis, particularly as micro- and nano-structured catalysts. Nevertheless, a systematic understanding of AMOFs remains limited, especially regarding material selection and application-driven structural design. Moreover, achieving controllable synthesis of these materials continues to pose significant challenges. In this review, we present a comprehensive classification system and outline the core synthetic strategies for AMOFs. We also highlight their representative catalytic applications over the past decade. This work aims to enhance the understanding of AMOFs development, advance their catalytic applications, and identify key challenges in synthesis and design, along with potential directions for future optimization.
