ABSTRACT: This study reports a facile and novel synthesis of a graphite/reduced graphene oxide (graphite/rGO) hybrid material derived entirely from waste palm kernel shell (PKS). To the best of our knowledge, no previous work has successfully hybridized graphite and rGO from a common biomass precursor, nor established a clear analytical route to confirm their hybridization. In this work, PKS-derived graphite and rGO were physically integrated through a facile one-pot hydrothermal method, forming a well-bonded hybrid with enhanced interlayer compatibility. The hybridization was evidenced through energy-dispersive X-ray (EDX) elemental analysis, revealing an optimized carbon-to-oxygen ratio intermediate between that of pure graphite and rGO, confirming the synergistic bonding between sp2 and partially reduced sp3 domains. Morphological and structural characterization were also incorporated. This simple approach provides a sustainable and scalable pathway to develop carbon-based hybrid materials for advanced electrochemical applications such as lithium-ion batteries and supercapacitor due to the combined properties from both graphite and rGO attributes.
