Electrochemical Evolution of Pore-Confined Metallic Molybdenum in a Metal–Organic Framework (MOF) for Pseudocapacitors

Abstract

In this thesis metallic molybdenum nanoparticles confined in the nanopores of a zirconium-based MOF (Zr-MOF) MOF-808 are prepared by a self-limiting decoration of spatially isolated Mo(VI) sites on the hexa-zirconium nodes of MOF-808 followed by the electrochemical reduction of Mo(VI) to metallic Mo The obtained pore-confined Mo exhibits reversible redox activity in a neutral aqueous electrolyte and is served as the pseudocapacitive material for negative electrodes By introducing another MOF-based pseudocapacitive material that can be used for positive electrodes a manganese-decorated Zr-MOF-carbon nanotube nanocomposite as a demonstration the all-Zr-MOF-based asymmetric pseudocapacitors with an aqueous electrolyte are fabricated
