Being conductive and flexible, MXenes, including transition metal carbides and nitrides, are expected to compete with, or even outperform graphene as 2D substrates serving in versatile applications. On the other hand, the extraordinary electrochemical activities of MXenes make them promising candidates as electrode materials in rechargeable batteries and supercapacitors, or as electrocatalysts in water splitting. However, MXenes are inclined to self‐restack due to hydrogen bonding or van der Waals interactions, which may lead to substantial loss of electroactive area as well as inaccessibility of ions and electrolytes. In this sense, hybridizing 2D MXenes and low‐dimensional inorganic nanostructures in elaborately designed architectures is of utmost significance, and provides a chance to integrate their unique properties in a complementary way. As such, this review is dedicated to highlighting recent progress in this regime, putting emphasis on the methods, structural and functional synergies, and energy‐related applications. Moreover, the present challenges and the future development directions are also discussed in depth.
