摘要
Abstract In this study, we propose a versatile method for synthesizing uniform three‐dimensional (3D) metal carbides, nitrides, and carbonitrides (MXenes)/metal–organic frameworks (MOFs) composites (Ti 3 C 2 T X /Cu‐BTC, Ti 3 C 2 T X /Fe,Co‐PBA, Ti 3 C 2 T X /ZIF‐8, and Ti 3 C 2 T X /ZIF‐67) that combine the advantages of MOFs and MXenes to enhance stability and improve conductivity. Subsequently, 3D hollow Ti 3 C 2 T X /ZIF‐67/CoV 2 O 6 composites with excellent electron‐ and ion‐transport properties derived from Ti 3 C 2 T X /ZIF‐67 were synthesized. The specific capacitance of the Ti 3 C 2 T X /ZIF‐67/CoV 2 O 6 electrode was 285.5 F g −1 , which is much higher than that of the ZIF‐67 and Ti 3 C 2 T X /ZIF‐67 electrode. This study opens a new avenue for the design and synthesis of MXene/MOF composites and complex hollow structures with tailorable structures and compositions for various applications.
