The heterostructures of different two-dimensional (2D) materials have garnered significant attention recently as emerging energy conversion and storage systems. Combining highly conductive and surface-active 2D MXenes with multifunctional 2D layered double hydroxides (LDHs) can leverage the constructive properties of both 2D materials. The synergistic interactions at the interface of MXene/LDH heterostructures enable them to exhibit commendable electrochemical performance and alleviate the disadvantages of the individual components. By comprehending the interfacial interactions between these two 2D materials, the structural, electronic, and morphological properties of the hybrid can be optimized. To this end, in addition to the discussions of the established synthetic methods for MXene/LDH hybrids, this article critically reviews their growth mechanism and factors influencing the morphology and chemical properties of the composites. Furthermore, the electronic interactions at the MXene/LDH heterointerface and their role in enhancing the electrochemical properties favorable to energy applications are systematically discussed. Finally, the key challenges and prospective research guidelines are provided to encourage further research to explore the synergistic effects of 2D/2D MXene/LDH hybrids in building better energy conversion and storage systems.
