Fundamental Investigations into the Metal-Organic Framework Redox-Hopping Charge Transport——Mechanisms and Improvement Strategies
Redox hopping is the dominant charge transport mechanism in many catalyst-modified metal-organic frameworks (MOFs). Previous studies have shown that ion diffusion is the rate-determining step of redox hopping, but the realization regarding to the fundamental mechanism of redox hopping in MOF is …

Functionalized Metal-Organic Frameworks for Water Oxidation Catalysis
… was anticipated to be primarily arose from redox hopping between RuTB active sites in the framework. In Chapter 3, RuTB-UiO-67 MOF thin films grown on conducting FTO substrate (RuTB-UiO-67/FTO) were synthesized to test their catalytic activity of electrochemical water oxidation. …

Investigations of Electron, Ion, and Proton Transport in Zirconium-based Metal-Organic Frameworks
… Additionally, we investigated in detail the redox-hopping electron transport mechanism previously proposed for MOFs, by utilizing the chronoamperometric response (I vs. t) of three metallocene-doped metal-organic frameworks (MOFs) thin films (M-NU-1000, M= Fe, Ru, Os) in two different …

Investigation of Charge Transfer in Metal-Organic Frameworks for Electrochemical Applications
… efficient charge transfer is a necessity. In redox-active MOFs, charge transfer can happen through redox hopping, i.e. site-to-site electron hopping coupled to diffusion of counter ions to balance electroneutrality. While the apparent diffusion coefficient (Dapp) has been employed to describe …

Investigations of Electron Transport Properties in Metal-Organic Frameworks for Catalytic Applications
… transport throughout the film was facilitated by redox hopping of electrons between the metal centers of the nodes and linkers. The ability to incorporate desired properties, such as pore functionalities or open metal centers, into frameworks makes them attractive for applications in separation of …

Zirconium-Based Metal-Organic Frameworks for Artificial Electrochemical Photosynthesis
… that charge transfer in MOFs can occur through a redox hopping mechanism in which the charge hops from redox center to redox center through space followed by the movement of a charge balancing ions. In Chapter 2, the charge transfer mechanism within the MOF is further investigated by utilization …
