Structural Characterization and Electrochemical Performance of Apricot Kernel-Based Activated Carbons for Supercapacitors
(Amer Chemical Soc, 2025) Onyilmaz, Elif; Onal, Yunus; Oz, Erdinc
Rapid industrialization and population growth have intensified global energy demands, emphasizing the need for sustainable and efficient energy storage systems. This study investigates the utilization of oil-extracted apricot kernels as a biomass precursor for activated carbon synthesis. Through carbonization and activation, two samples (ASE3 and ASE5-T) were produced and characterized using XRD, FTIR, Raman spectroscopy, SEM/EDX, BET analysis, and electrochemical testing. Among the samples, ASE3 demonstrated superior structural and electrochemical properties, highlighting its potential for energy storage applications. Structural studies revealed a micropore-dominated structure with hierarchical porosity, optimizing ion transport and charge storage. This approach provides a sustainable solution to waste management and paves the way for cost-effective alternatives to traditional energy storage materials. Future studies should explore the long-term cycling stability, the potential for industrial-scale production, and hybrid system integrations for energy storage solutions.
