Metal-organic framework-based nanomaterials have the potential to be used for energy applications, due to their controllable morphology and structure, large surface area, and various other multifunctional characteristics. They are made up of systematically structured and adjustable organic links and metal ions, or groups of metal ions that provide uniformity and well-defined active site conformation. This book addresses the current challenges and cover the design and fabrication approaches, for nanomaterials based on metal organic frameworks for energy generation and storage technologies. The effect of synthetic diversity, functionalization, ways of improving conductivity and electronic transportation, tuning-in porosity to accommodate various types of electrolyte, and the criteria to achieve the appropriate pore size, shape, and surface group of different metal sites and ligands are explored. The effect of integration of other elements, such as second metals or hetero-atomic doping in the system, to improve catalytic activity and durability, are also covered. This is an important reference source for materials scientists, engineers and energy scientists looking to further their understanding of how metal organic framework-based nanomaterials are being used to create more efficient energy conversion and storage systems.
