Özet
Air pollution caused by fossil fuels is the biggest problem humanity has ever created, and clean energy sources like hydrogen are seriously needed to solve it. Therefore, in this study, four phenanthrene-based hyper-crosslinked polymers (PTHCP-1–4) were synthesized via Friedel–Crafts alkylation and characterized by FTIR, BET, SEM, XPS, TGA, and zeta potential measurements. The BET surface areas ranged from 518.9 to 908.8 m2 g-1, with PTHCP-4 showing the highest value, while pore volumes varied between 0.24 and 1.60 cm3 g-1. SEM revealed uniform nanoscale particles for PTHCP-2 (mean size 54 nm) and aggregated morphologies for PTHCP-3/4. XPS confirmed incorporation of pyridinic-N (399.3 eV) and phenolic –OH groups, and TGA demonstrated high thermal stability with main degradation above 400 °C. Zeta potentials shifted from +36.3 mV (PTHCP-3) or −6.48 mV (PTHCP-1) to more negative …
