| Özet |
| Four novel hyper-crosslinked polymers (HCP-1 to HCP-4) were synthesized via Friedel–Crafts alkylation using 4,4′-bis(chloromethyl)-1,1′-biphenyl as the crosslinker and various aromatic monomers including triphenylphosphine (TPP). These polymers were designed as metal-free catalysts for hydrogen generation via sodium borohydride methanolysis. Comprehensive characterization using FT-IR, XPS, BET, TGA, SEM, and zeta potential analyses confirmed that the materials possess thermally stable, porous networks with irregular morphologies and distinct surface charges. Under practical conditions, HCP-3 exhibited the highest catalytic activity with a hydrogen generation rate of 9857 mL H2 min−1 g−1 at 303.15 K and the lowest activation energy (Ea = 32.0 kJ mol−1). At elevated temperature (333.15 K), HCP-2 achieved the highest activity (37,200 mL H2 min−1 g−1), reflecting the strong influence … |
