| Özet |
| Fluoranthene-based hyper-crosslinked polymers (HCPs) were synthesized via Friedel–Crafts alkylation and evaluated as metal-free catalysts for hydrogen generation through NaBH4 methanolysis. Despite moderate hydrogen-generation rates relative to some polymeric systems, the catalysts exhibited distinct structure–activity behavior that could not be explained by surface area or heteroatom content alone. Notably, HCP-4 achieved the highest hydrogen-generation rate (31,200 mL H2 min−1 gcat−1 at 333.15 K), whereas HCP-1 showed the lowest apparent activation energy (23.6 kJ mol−1), indicating decoupled kinetic and textural contributions. Zeta-potential analysis revealed pronounced reaction-induced modulation of surface charge, identifying interfacial electrostatics as a dominant mechanistic factor governing hydride activation. These findings demonstrate that π-conjugated polymer architecture and … |
