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 C T /Cu-BTC, Ti C T /Fe,Co-PBA, Ti C T /ZIF-8, and Ti C T /ZIF-67) that combine the advantages of MOFs and MXenes to enhance stability and improve conductivity. Subsequently, 3D hollow Ti C T /ZIF-67/CoV O composites with excellent electron- and ion-transport properties derived from Ti C T /ZIF-67 were synthesized. The specific capacitance of the Ti C T /ZIF-67/CoV O electrode was 285.5 F g , which is much higher than that of the ZIF-67 and Ti C T /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.
在本研究中,我们提出了一种通用方法来合成均匀的三维(3D)金属碳化物、氮化物和碳氮化物(MXenes)/金属有机框架(MOFs)复合材料(Ti C T /Cu-BTC、Ti C T /Fe,Co-PBA、Ti C T /ZIF-8和Ti C T /ZIF-67),该方法结合了MOFs和MXenes的优点,以提高稳定性并改善导电性。随后,合成了具有优异电子和离子传输性能的3D中空Ti C T /ZIF-67/CoV O复合材料,其源自Ti C T /ZIF-67。Ti C T /ZIF-67/CoV O电极的比电容为285.5 F g ,远高于ZIF-67和Ti C T /ZIF-67电极。本研究为设计和合成具有可定制结构和组成的MXene/MOF复合材料及复杂中空结构以用于各种应用开辟了一条新途径。
