类沸石咪唑酯骨架化合物ZIF-67的超声波辅助快速合成及其超级电容性能研究
Research on ultrasonic assisted rapid synthesis of zeolitic imidazolate framework-67(ZIF-67) and its supercapacitor performance
摘要
Abstract
A large amount of size tunable zeolitic imidazolate framework-67 (ZIF-67) was synthesized in a shot time with ultrasonic assisted method.The structure and morphology of synthesized materials were characterized with XRD and SEM.Nitrogen adsorption-desorption technique was also used to characterize the synthesized ZIF-67.Results showed that the ZIF-67 prepared by this method had higher crystallinity,regular rhombic dodecahedral morphology,and higher porosity and specific surface area.As supercapacitor electrode materials,cyclic voltammetry (CV) and galvanostatic charge/discharge (GCD) measurements were carried out to test the electrochemical performance of synthesized materials.The results showed that ZIF-67 synthesized by ultrasonic assisted method delivered a specific capacitance of 93 F/g at 0.5 A/g,which was much higher than that of ZIF-67 synthesized under static condition.When current density was 1 A/g,the specific capacitance of ZIF-67 synthesized by ultrasonic assisted mehtod could be retained to 98.6％ of the initial value after 1000 cycles.demonstrating the excellent cycling stability.关键词
