Structure engineering and electrochemical applications of metal-organic framework-based materials
- Metal-organic frameworks (MOFs) are a class of crystalline porous solids consisting of metal ions or clusters coordinated to organic ligands. Because of their appealing features such as regular and adjustable pore size, large specific surface area, and diverse topologies and morphologies, MOFs are traditionally used in many applications including gas/vapor separation, gas storage, and catalysis. In the past decade, MOFs have been identified as a promising platform in electrochemical applications. The very recent advances in electrically conductive MOFs further enhanced the prospect of electrochemical applications for MOFs. Despite the increasing interest of applying MOF-based materials in many electrochemical applications, there is still much to be investigated, including the stability, particle size engineering, electronic property, and novel structure development for the next generation of MOF-based materials to promote their electrochemical applications. In this work, I explore the possibility of employing metal-organic framework (MOF)-based materials in electrochemical applications. Chapter 1 introduces the background and motivation of this thesis. Chapter 2 demonstrates the efforts to employ an Aluminum porphyrinic MOF for oxygen reduction reaction. Chapter 3 focuses on particle size study in oxygen electroreduction done by a Zirconium porphyrinic MOF with impressive stability in acidic electrolyte, which provides general guidelines for utilizing non-conductive MOF materials in electrocatalysis. Chapter 4 presents tuning the electronic properties of a series of conductive MOFs comprised of otcaaminophthalocynine ligands and divalent transition metals (Co, Ni and Cu) and then studied their electrocatalytic performances in oxygen reduction under basic condition. The remainder of the dissertation focuses on the design and synthesis of a 3D conductive MOF and its valence-dependent conductivity. These findings provide general guidelines for utilizing MOF materials in electrochemical applications.
