Metal-organic framework modified carbon nanotubes for hydrogen production from formic acid with carbon dioxide capture and conversion.

ABSTRACT: The increasing demand for sustainable energy and the need to reduce carbon emissions have driven research into advanced materials for hydrogen production and CO₂ capture. This study presents a novel copper-based metal-organic framework (Cu-MOF) integrated with Multiwalled carbon nanotubes (MWCNTs) as a photocatalyst for hydrogen (H₂) generation and carbon dioxide (CO₂) capture. The composite's structural, thermal, and morphological properties were analyzed using FTIR, XRD, TGA, and SEM/EDS. Photocatalytic performance was evaluated using formic acid, yielding 11 mmol/g of gas with 75% H₂ purity, confirmed by gas chromatography. Post-reaction analysis revealed CO₂ capture and reversible photoelectrocatalytic behavior. The composite shows promise for scalable, sustainable hydrogen production
