Synthesis of Metal-Organic-Framework Derived Materials for Energy Storage Applications

Abstract

With the progress in industrialization, the scarcity of resources and environmental pollution is growing fast. On the one hand, carbon dioxide produced by the ordinary combustion vehicle is a major source of global warming, where the fuel cars are accounted to consume a huge amount of oil resources. On the other hand, as the world has realized the importance of environmental protection, the development of a low carbon transportation system has become an important solution. The electric vehicle has brought a lot of benefits, such as environmentally friendly, clean and no pollutant emissions. As a result, it might be regarded a potential new energy vehicle that has piqued the interest of consumers, industry, and researchers. Supercapacitors were also known as ultra-capacitors are being evaluated as one of the viable energy storage choices for future generations. These gadgets have been found to be useful in a range of applications, namely powering hybrid electric/electric automobiles and other electrical and electronic devices that enable energy to perform. Supercapacitors are the most flexible devices, widely used for supplying electrical energy quickly and in applications that need a long shelf life. As a result, there are considerable market demands for supercapacitors' development, and long-term advancement is necessary for their successful improvement and commercialization. New electronic and optoelectronic gadgets have recently grown on the market, requiring more dependable power sources with higher energy density and longer duration. Owing to their, pollution-free nature, stability, and high power density, supercapacitors have emerged as feasible options for energy storage. Traditional supercapacitors' poor energy density prevents them from being widely used, leading researchers to look into new forms of supercapacitors with better performance. Increasing the electrochemical performance of supercapacitors through the development of innovative electrode materials has been a major focus of study in recent decades. Asymmetric supercapacitors (ASCs) made consisting of two different electrode materials xi have a large working voltage window, enabling them to substantially increase energy density. In this research work, asymmetric super-capacitors electrode (ASCs) has been fabricated using Metal-Organic-Frameworks (MOF) derived mixed metallic oxides @CC as a positively charged electrode and MOF-derived nanoporous carbon (NPC) based material as a negatively charged electrode by a cost-effective hydrothermal method. The substantial materials are zinc-cobalt nitrates and 2-methylimidazole. The hydrothermal method is used to produce all samples.
