Abstract
In this work, the electrochemical performance of in-situ grown ZIF-67 nanosheets on nickel foam (ZIF-67@NF) is reported. The nanosheets were synthesized via a one-step hydrothermal method and characterized using different techniques to confirm their crystal structure, functional groups, and morphology. Electrochemical tests revealed that ZIF-67@NF delivered a high specific capacitance of 2195.23F/g at 1 A/g and retained 1000F/g at 10 A/g. The material demonstrated excellent cycling stability of 83.07% after 10,000 cycles at 10 A/g, showcasing its potential for high-performance supercapacitors.
本文报道了原位生长的ZIF-67纳米片在泡沫镍（ZIF-67@NF）上的电化学性能。通过一步水热法合成了纳米片，并使用不同的技术对其晶体结构、官能团和形貌进行了表征。电化学测试表明，ZIF-67@NF在1 a /g时具有2195.23F/g的高比电容，在10 a /g时保持1000F/g。该材料在10 A/g下循环10,000次后表现出优异的循环稳定性，达到83.07%，展示了其作为高性能超级电容器的潜力。
