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 (Ti₃ C₂ T_X /Cu-BTC, Ti₃ C₂ T_X /Fe,Co-PBA, Ti₃ C₂ T_X /ZIF-8, and Ti₃ C₂ T_X /ZIF-67) that combine the advantages of MOFs and MXenes to enhance stability and improve conductivity. Subsequently, 3D hollow Ti₃ C₂ T_X /ZIF-67/CoV₂ O₆ composites with excellent electron- and ion-transport properties derived from Ti₃ C₂ T_X /ZIF-67 were synthesized. The specific capacitance of the Ti₃ C₂ T_X /ZIF-67/CoV₂ O₆ electrode was 285.5 F g^-1 , which is much higher than that of the ZIF-67 and Ti₃ C₂ 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.
