Abstract:
Successful synthesis of three kinds of dynamically stable compounds by a simple grinding method is reported, giving Ag6 Mo7 O24 , Ag-BTC (Ag-MOF, BTC=benzene-1,3,5-tricarboxylic acid), and {Ag6 Mo7 O24 }@Ag-MOF metal-organic frameworks (MOFs). According to the electrochemical dynamic analysis, these materials have pseudocapacitor behavior and high capacitance. The unique nanorod structure of {Ag6 Mo7 O24 }@Ag-MOF provides more active sites, faster ion/electron transfer, and electrolyte diffusion pathways, resulting in excellent specific capacitance (971 F g-1 ) higher than the other compounds. {Ag6 Mo7 O24 }@Ag-MOF (glassy carbon electrode) also has an excellent rate ability (60.1 %) and long cycle stability (98 % retention after 5000 cycles). In addition, the fully symmetrical button battery (with nickel foam as the current collector) fabricated with {Ag6 Mo7 O24 }@Ag-MOF delivers an energy density of 11.1 Wh kg-1 at 600.1 Wh kg-1 coupled with excellent cycling stability (86.4 %) at 1.2 V. These results demonstrate a new simple grinding method to prepare polyoxometalate-based metal-organic frameworks (POMOFs) for high-performance materials.
