Graphene Oxide Templated Growth of MOFs with Enhanced Lithium-Storage Properties

Abstract

Mn-MOF/RGOn composites have been successfully synthesized by using terephthalic acid non-covalent functionalized graphene oxide (GO) sheets acting as efficient nucleation sites and structure-directing template to direct the growth of MOFs. The electrochemical performance of Mn-MOF/RGOn composites electrode was much better than that of the pristine Mn-MOF when used as a candidate anode material for lithium-ion batteries, benefiting from the synergetic advantages of RGO and Mn-MOF, improved electrical conductivity and mechanical flexibility of Mn-MOF. Especially, the Mn-MOF/RGO10 composite electrode maintains a reversible discharge capacity of 715 mA h g−1 with capacity retention of 98% after 100 cycles at 100 mA g−1, and also exhibits high discharge capacity of 485 mA h g−1 at 300 mA g−1, 432 mA h g−1 at 500 mA g−1 while still 348 mA h g−1 at 1000 mA g−1 after 500 cycles, which is drastically increased compared with pure Mn-MOF material as expected.
