Title: Synthesis, characterization of a novel material Co-ZSM5 for Supercacitor
Abstract:
Zeolite composites derived steam-assisted crystallization method as electrode materials for supercapacitor applications has not been extensively reported. Although Zeolites exhibit exceptional surface area, high porosity, and well-controlled structure, they present relatively low conductivity, hindering their successful application in supercapacitor electrodes fabrication. In this work, we report the synthesis of Zeolitic composites (ZSM5, HZSM5) by the facile impregnation method. Among the alternative materials that show great potential for electrode material application, sulphides, nitrides, metal oxides, and other conductors are attracting particular attention. Moreover, other conductors or pseudo materials (Materials based on zeolites) may exhibit low conductivity but have other remarkable advantages such as high specific surface and multiple oxidation states during the electrochemical process [1]. Enhancement of the specific capacitance in electrochemical double layer capacitors (EDLCs) is of high interest due to the ever-increasing demand for high power density energy storage devices. Zeolite templated carbon (ZTC) is a promising EDLC electrode material with large specific surface area and straight, ordered well-defined micropores[2].Furthermore, in electrochemistry, the application of Zeolites is somewhat limited because they have no redox metals in their structure. For this reason, it is therefore judicious to introduce or incorporate metals or metal oxides into the framework of the zeolite to initiate the retained activity[3]. So, we synthesized zeolite ZSM5 an then impregnate with cobalt and the obtained material was Co-ZSM5. We did some analysis as Bet, Sem, FTIR, XPS, XRD (will explained very well during the presentation). Then we did electrochemical analysis and we noticed that our novel material has a good specific capacitance compare to the literature and also maintained 98% retention after 5000 cycles. So, from this work, everyone who has a relation with supercapacitor will know that Co-ZSM5 is a good supercapacitor material. This will provide a practical solution to a problem that could simplify or make a designer’s job more efficient because from this work, many professors could also expand this field trying to synthesize other catalysts based on zeolite with another metals. This material could provide energy storage and source balancing when used with energy harvesters and improve load balancing when used in parallel with a battery.
