From Structure to Functional Implications: Investigation of the Melon-Like Framework of Graphitic Carbon Nitride for Li-S Batteries.

ABSTRACT: Graphitic carbon nitride (gCN) has emerged as a promising material for sustainable energy storage applications, photocatalysis, and sensors. Despite extensive research, its precise crystallographic structure remains controversial, particularly regarding the distinction between heptazine-based and melon-like frameworks. In this study, we investigate the structural characteristics of gCN synthesized using different precursors, urea and melamine. Comprehensive characterization, including X-ray diffraction (XRD), confirms that all samples exhibit a melon-like framework with P2₁2₁2 symmetry. This contradicts the widely cited but experimentally unsupported heptazine-based model. We further explore how precursor selection influences crystallinity, elemental compositio
