Abstract

The pursuit of sustainable energy technologies demands advanced materials capable of addressing the limitations of conventional thermal energy storage (TES) systems. Traditional materials often suffer from low energy density, poor heat retention, and stability issues under cyclic operation, prompting the exploration of new hybrid systems. This work presents the synthesis, characterization, and theoretical analysis of a novel MXene/MIL-53(Al)-derived Al2O3/C composite designed for next-generation thermal energy storage and conversion. The combination of Ti₃C₂Tₓ MXene, known for its remarkable electrical and thermal conductivity, with the highly porous and thermally stable MIL-53(Al) framework, results in a synergistic material exhibiting enhanced structural and functional properties. Experimental analyses such as XRD, FTIR, SEM-EDX, XPS, and TGA confirm the successful integration of the two phases, revealing robust interfacial bonding and improved thermal stability up to 400 °C. Theoretical density functional theory (DFT) investigations further elucidate the electronic interactions at the MXene–MOF interface, indicating strong Ti–O–C and Al–O–Ti coordination and a narrowed bandgap that enhances charge transport and thermal conductivity. The hybrid composite demonstrates promising physicochemical performance compared with pristine MXene, highlighting its promise as a high-efficiency material for sustainable thermal management and renewable energy transfer and storage systems. This study doesn't include direct measurements of thermal conductivity or latent heat also the absence of pure MIL-53(Al) hydrothermal control experiment under identical conditions represents a limitation of this study. Consequently, the discussion of thermal energy application potential discussed is based on structural and thermal stability characteristics only.
