In response to the growing demand for sustainable and resource-efficient alternatives in synthetic chemistry, this study explores the untapped potential of Algerian coal as a renewable, nanostructured, carbon-rich material. Traditionally perceived as a fossil energy source, this indigenous and underutilized resource is revisited for its suitability in eco-friendly and advanced synthetic organic applications.

A comprehensive physicochemical characterization was carried out using Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD) with Rietveld refinement, Fourier Transform Infrared Spectroscopy (FTIR), and Raman Spectroscopy. The analyses revealed a heterogeneous, porous structure dominated by carbon (98.8%) and silica (1.2%), with nanocrystallites averaging ~18 nm in size. Raman spectroscopy confirmed the presence of both graphitic and disordered carbon domains—an ideal structural configuration for molecular adsorption, surface functionalization, redox reactivity, and catalytic activity.

These findings suggest a transformative role for Algerian coal as a sustainable feedstock in the design of porous nanocomposites, supramolecular carbon-based architectures, hybrid polymer systems, and smart functional materials. This study presents the first nanoscale investigation of this local raw material, opening new interdisciplinary perspectives for its integration into green synthetic processes and emerging materials chemistry.

By reimagining coal as a functional platform rather than merely a fuel, this research contributes to circular economy strategies and advances innovation within synthetic organic, environmental, and materials chemistry.
