Summary: The electrochemical performance of divalent (Mn, Fe, Zn) substituted NiCo2O4 nanorods, developed using a facile hydrothermal route, was investigated. Mn substitution showed the best performance among the divalent replacements, exhibiting a specific capacitance of 1272 F/g, an energy density of 35.77 Wh/kg, and a power density of 660.39 W/kg. Fe and Zn substitution resulted in lower capacitance compared to pure NiCo2O4, likely due to lower catalytic activity. Mn substituted NiCo(2)O(4) demonstrates the potential for high performance supercapacitor applications.

Summary: The conversion of plastic waste into high-value metal-organic framework (MOF) materials is an important research area for mitigating environmental and economic issues. MOFs have significant advantages as supercapacitor electrode materials due to their large surface area and high porosity. In this study, MOFs were successfully produced from PET bottles using a hydrothermal approach, and the Cu-MOF showed higher capacitance and diffusion contribution compared to Zr-MOF and Ti-MOF. Additionally, solid-state symmetrical supercapacitor devices using these MOFs exhibited excellent performance, particularly the Cu-MOF//Cu-MOF device with high energy density and cyclic stability.
