摘要: 通过超声波辅助的方法，在较短时间内合成大量粒径可控的ZIF-67材料.利用XRD和SEM对合成的ZIF-67进行结构表征和形貌分析，并对其进行氮气等温吸脱附测试，结果表明：该方法制备的ZIF-67具有更高的结晶度、规整的菱形十二面体形貌，以及较高的孔隙度和比表面积.将其作为超级电容器电极材料，利用循环伏安、恒流充放电等电化学测试方法研究其电化学性能，结果表明：当电流密度为0.5 A/g时，超声波辅助合成的ZIF-67比电容为93 F/g，大于静置条件下合成的ZIF-67；当电流密度为1 A/g时，超声波辅助合成的ZIF-67充放电循环1000次后，其电容保持率为98.6%，具有优异的循环稳定性.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.
