Article Description

Strategically engineering composite materials holds considerable importance in research for enhancing electrochemical characteristics in advanced energy storage devices. Within this context, we explored the potential of a heterostructured material as an electrode for high-performance battery-type electrodes for supercapatteries, individually evaluating the material's components. We synthesized MCM-41, functionalized-MCM-41, ZIF-8, and ZIF-8@NH-MCM-41 heterostructured material and examined the individual physicochemical characteristics to gain insights into their collective properties when combined. X-ray diffraction patterns confirmed the successful preparation of the heterostructure, while spectroscopic analyses indicated the possible chemical interactions of these materials. Also, nitrogen adsorption-desorption isotherms suggested a new porous architecture for the ZIF-8@NH-MCM-41 material, making it suitable and highly interesting for storage issues. ZIF-8@NH-MCM-41 material exhibited a high specific capacity (356.11 mAhg-1) with excellent retention. When used to create an asymmetric supercapacitor, the heterostructure showed an energy density of 48.43 Whkg-1 at a power density of 3113 Wkg-1 at 1 Ag-1. Even after 1000 cycles at 8 Ag-1, the material demonstrated excellent stability and potential for future applications. Thus, this work demonstrates the potential of heterostructured materials for high-performance supercapacitors, providing a viable route forward for energy storage applications.
