Abstract
(2.5-fold) was achieved through incorporation of the NBs, along with the introduction of microporosity, which significantly improved ion diffusion kinetics relative to previous methodologies. FTIR analyses confirmed the rise in oxygenated functional groups, mostly C-O entities, which improved the surface reactivity of GO@NBs. XRD confirmed the increase in crystallinity as well as greater crystal size in GO@NBs, while SAXS confirmed the structural integrity as well as material porosity. Air NBs, therefore, impact the physicochemical properties of GO extensively and reveal significant opportunities for energy storage, catalysis, and remediation.
