摘要
能源短缺问题受到越来越多的关注,急需发展清洁和可再生能源.近几十年来,一种新型的功能性金属有机骨架(MOFs)材料,因其具有周期性的网状结构、大空隙率和比表面积,在电化学元器件比如超级电容器的材料制备方面有非常可观的应用前景.文中主要通过热溶法制备了不同金属有机骨架材料及其衍生碳材料,并对MOFs材料进行了XRD和红外光谱表征来分析其合成情况;对其碳化物的相关电化学性能进行测试,来检验MOFs系列材料应用于超级电容的可能性.测试结果表明:文中成功制备出了Co-MOF、Ni-MOF和Co-Ni-MOF,碳化物的电化学性能为Ni-MOF优于Co-Ni-MOF优于Co-MOF,其中Ni-MOF碳化物的放电比容量达到了63.3(mA·h)/g,说明MOFs系列碳化物电容性能优异,具有广阔的应用前景.
The problem of energy shortage is concerned by a increasing number of people.We need a technological revolution to develop clean and renewable energy.In recent decades,a new type of functional metal organic framework(MOFs)material has been found to have periodic network structure,large porosity and specific surface area,so it has a considerable application prospect in the preparation of electrochemical components such as super capacitors.In this study,different metal organic framework materials and their derived carbon materials were prepared by hot-melt method,and the synthesis of MOFs materials was tested by XRD and IR,and the electrochemical properties of carbides were tested to examine the possibility of MOFs series materials applied to supercapacitors.The results show that CO-MOF,Ni-MOF and Co-Ni-MOF have been successfully prepared.The electrochemical property of the carbide of Ni-MOF is better than that of Co-Ni-MOF and the latter is better than that of Co-MOF,and the specific discharge capacity of Ni MOF carbide is 63.3(mA·h)/g.Therefore,the application prospect of MOF series carbon materials in capacitance is very broad.
