Metal-organic framework derived carbon-based composites and their utilization in electrochemical power sources
Original language description
Metal organic frameworks (MOFs) are defined as microporous crystalline solids constructed from metal ions or metal-oxo clusters crosslinked with an organic linkers.1 The use of different metal precursors and adjustable carbon-containing linkers allows for tuning the final properties of MOF materials.2 Moreover, MOFs can be employed as precursor templates for porous and highly homogeneous carbon-based composite materials and metal oxides.3 MOF derived composite materials based on porous carbon and transition metal oxides are nowadays featured as promising components in electrochemical power sources. In this work we describe a microwave-assisted synthesis of metal organic framework based on manganese and cobalt with the use of biphenyl-4,4´-dicarboxylic acid as a linker. The utilization of microwaves enables focused heating of reaction mixture and thus the reaction time is reduced. Obtained MOF products (Mn-Bpdc, Co-Bpdc) were transformed to hybrid carbon based composites with metallic cobalt or manganese(II) oxide via heat treatment in an atmosphere of nitrogen. Finally, we tested a potential application of MnO-carbon and cobalt-carbon composites in Lithium-sulfur batteries and Sodium-ion batteries, respectively.
