Aloe vera-derived NiCo₂O₄ electrodes with improved cyclic efficiency for supercapattery applications.

ABSTRACT: Green synthesis is a sustainable and environmentally friendly approach for designing efficient electrode materials to meet the growing demand for supercapattery electrodes. In this work, Aloe vera-assisted synthesis of phase-pure spinel NiCo₂O₄ nanomaterial was achieved through a simple and eco-friendly route. Synchrotron XRD confirmed excellent crystallinity and phase purity, while FTIR identified characteristic metal-oxygen bonds together with Aloe vera-derived organic functionalities. FESEM and TEM provided morphological insights, while BET analysis, confirming mesoporosity with a surface area of 18.61 m² g^-1, and average pore diameter of ~ 14.7 nm. Synchrotron XPS revealed mixed Ni/Co oxidation states and abundant oxygen vacancies, which prom
