Photocatalytic and Electrochemical properties of Metal Organic Frameworks and their Composites with Inorganic Semiconductors

Abstract

The thesis presents the work related to Metal Organic Frameworks and their composites with newlineinorganic semiconductors fabricated with nanoparticles their synthesis, Characterization, newlinePhotocatalytic and thermal studies. Metal-organic frameworks (MOFs) are a relatively new newlineclass of ordered porous solids that have been investigated for the past few decades. MOFs are newlinecrystalline coordination polymers composed of inorganic ions or ion clusters and organic newlinelinkers, forming complexes which then self assemble into one, two, or three-dimensional newlineframeworks. The organic ligands involved are sometimes referred to as Struts for example newline1, 4-Benzenedicarboxylic acid. MOFs can be used for gas storage, purification and newlineseparation as well as catalysis and sensing application. The MOFs area of research is of newlineparamount importance. The advantage and beauty of this class of materials is that by newlinecarefully choosing metal ions and organic ligands, it is possible to tailor the structures and newlinesizes of pores within the MOFs by designing appropriately. Because of the wide variety of newlinecoordination geometries offered by transition, lanthanide metal ions and the rich number of newlinestructures and reactive functionalities that can be incorporated into organic linkers via newlineorganic synthesis, MOFs provide a means to generate a diverse range of framework newlinearchitectures. An important and advantageous characteristic feature of MOFs is their [1] newlineextremely high surface areas and void volumes and pore openings ranging from 3Å up to newline20Å that become highly accessible to organic guests [2]. As such, MOFs represent a unique newlineclass of ordered porous materials having great potential as hosts in applications where pore newlinedimensions exceeding those of zeolites, is required. With the advent of a large body of newlinesynthetic protocols for preparing MOFs, researchers are now exploring the host-guest newlineContents/Abstract Photocatalytic and Electrochemical Properties of MOFs and Composites newlinePh.D Thesis (2019) xxii newlinebehavior of MOFs in many areas of Chemistry, with
