Hydrogen Production from Formic Acid Decomposition Promoted by Gold Nanoparticles Supported on a Porous Polymer Matrix.

ABSTRACT: Formic acid (FA) is considered one of the most promising carriers of clean and safe dihydrogen. This study highlights the potential of using poly-(2,6-dimethyl-1,4-phenylene oxide) (PPO) as a support for AuNPs to produce H₂ through formic acid dehydrogenation (FAD). The developed synthesis method allows for precise control over the gold content by completely encapsulating AuNPs (4-6 nm) within the PPO matrix, ensuring a uniform distribution of nanoparticles with an active cubic morphology. In an aqueous solution (or a water/DMAc mixture), the catalyst exhibited high activity, generating H₂ without producing CO, underscoring its high selectivity for dehydrogenation. At 105 °C, the catalyst showed a TOF of 360 mol_FA·mol_Au ^-1·h^-1
