Metal organic frameworks (MOFs) are the new class of porous materials linked by organic linkers (struts) and metal nodes or clusters.1 Their diverse morphological aspects, high porosity, tunable pore size (10-20 Å) and adjustable internal surface properties makes them a potential catalysts in sensor, separation & purification technologies, catalysis, drug delivery, gas & energy storage technologies.2 However, their low thermal stability and conductivity minimizes its use. Therefore, MOFs have appeared as a promising sacrificial templates/precursors to construct various micro/nanostructured materials for energy storage applications. MOF derived materials such as metal oxides/hydroxides, metal sulphides, carbons or composites can be prepared by post synthetic modification (PSM) of MOFs while retaining the shapes of the pristine MOFs.3 Among various transition metal oxides/hydroxides or sulphides, Ni, Co and Zn oxides/hydroxides or sulphides are considered to have potential application in energy storage technologies such as supercapacitor and fuel cells.4 On the other hand, MOF derived nanocomposites such as Co3O4/NiCo2O4, NixCo3-xO4/Graphene, Ni-Co-O@CFP//NPC etc. has been developed to increase their practical application. Moreover, taking into account the variety of MOF derived materials and their composites have a potential to provide active sites for reactive adsorption of electrolytes.5 In this presentation, I will discuss about the fundamental of MOFs/ MOF derived materials such as ZnCoS/N-rGO, ZnCdS/g-C3N4, NixCo3-xO4/Graphene and their application into energy storage system.
