Topic of Research Seminar: Metal-organic Framework derived electrocatalyst for water-splitting application
Abstract: Metal-organic frameworks (MOFs) have garnered significant attention over the past two decades due to their unique composition of inorganic metals and organic ligands as the fundamental building blocks forming crystalline structures. Metal-organic frameworks are crystalline, having a large surface area, high porosity and a maximum number of unsaturated sites metals. Moreover, the large pore size of the MOF permitted the guest or functional material into their cage dynamically enhance the catalysis activity MOF materials have been used as a catalyst across a diverse spectrum of applications, including gas adsorption and storage, separation processes, catalytic reactions, dye adsorption, drug delivery systems, electrode material development, and serving as carriers for various nanomaterials. Among the various applications, a prominent role emerges in electrocatalysis for hydrogen production via water splitting. An eco-friendly water splitting (electrolysis) process comprises two basic reactions that is; Hydrogen evolution reaction (HER) in which pure hydrogen evolved at the cathode, and Oxygen evolution reaction (OER) in which oxygen and hydrogen evolve at an anodic surface. During the process, a large amount of energy is required to split the water molecule; therefore process faces sluggish kinetics. MOFs can be efficient catalysts due to their versatile potential for water-splitting applications. So, Metal-organic Frame work-based catalyst is designed by conjugation of transition metal with a linker and to enhance the stability of the catalyst, composites are designed by carbon-based material. This strategic combination aims to synergistically improve the material’s physical, chemical, and catalytic characteristics. The designed material’s morphology, crystallinity, specific surface area and function group are examined by XRD, SEM, BET and FTIR. The Electrochemical activity of the catalysts are determined by Cv, LSV, EIS and Chronopotentiometry.
