| Özet |
| Hydrogen energy is widely regarded as one of the most promising alternatives to fossil fuels. This study focuses on the synthesis of an environmentally friendly zwitterionic polymer catalyst, Poly(Quaternized-2-diethylaminoethyl methacrylate) (P(Q-DMA)), was synthesized and evaluated for the first time as a metal-free catalyst in NaBH4 methanolysis for hydrogen production. Owing to its zwitterionic nature, P(Q-DMA) was designed to interact synergistically with methanol and sodium borohydride through multiple mechanisms, including ion–dipole, ion–ion, and hydrogen-bonding interactions. The structure–function relationship was investigated using surface analysis (BET, SEM and Zeta), chemical characterization (FTIR, TGA), and kinetic modeling. Systematic optimization revealed high catalytic efficiency, achieving a hydrogen generation rate (HGR) of 443.4 mL H2 min−1 gcat−1 and a mass-specific HGR of 8868 … |
