dc.description.abstractThis study focuses on the optimization and characterization of a grass waste-derived catalyst, GW-Ni-Cat, for hydrogen generation via NaBH4 methanolysis, as well as its application in supercapacitors. Optimization experiments were conducted to determine the optimal conditions for acid concentration, metal concentration, carbonization temperature, and carbonization time. The catalyst was characterized using various techniques including FTIR, XRD, SEM, TEM, BET, and ICP-OES. Performance experiments demonstrated the catalyst's efficiency in hydrogen generation, with key factors such as catalyst amount, NaBH4 concentration, and temperature influencing the reaction kinetics. Reusability tests showed the catalyst's stability over multiple cycles. Electrochemical characterization revealed the suitability of GW-Ni-Cat as an electrode material for supercapacitors, with high specific capacitance values. Comparison with other bio-based supercapacitors demonstrated the superior performance of GW-Ni-Cat. Overall, this study presents GW-Ni-Cat as a versatile and efficient material for both hydrogen generation and energy storage applications. © King Fahd University of Petroleum & Minerals 2024.
