The research for metal organic frameworks (MOFs)- and covalent organic frameworks (COFs)-based functional composites has attracted continuous attention due to their excellent synergistic properties. With the increasing interest in expanding the diversity and properties of multi-component framework materials, the commonness and uniqueness of MOFs and COFs build a bridge for the potential development of meritorious MOFs-COFs composites. This minireview comprehensively introduced the recent development of MOFs-COFs composites from their syntheses to enhanced applications. Starting from the preparation methods, MOFs-mediated MOF@COF composites and COFs-mediated COF@MOF composites fabricated under various synthetic conditions are introduced, respectively. Furthermore, the enhanced application performance of the MOF@COF composites and COF@MOF composites in catalysis and their potential applications in adsorption and separation, energy storage and sensing are summarized. Followed by the above discussion, we further highlight the opportunities and challenges faced by MOFs-COFs composites. Altogether, this minireview is expected to provide inspiration for the development of the dazzling but embryonic MOFs-COFs composites.
