Özet
Catalyst efficiency is affected by inhomogeneous catalyst atom placement on the substrate, leading to nano-level aggregation and reduced performance. Research on single-atom catalysts aims to place them at the atomic level to maximize efficiency, but faces challenges and high costs. This study presents a cost-effective approach using polymeric phthalocyanine Co(II) complex (poly-CoPc) prepared by a simple method. Poly-CoPc shows superior catalytic activity by acting as a catalyst without requiring additional processing. Co(II) atoms in the polymer matrix are covalently coordinated into single atoms and inhibit nanoparticle growth. The poly-CoPc/PMS system outperforms Co3O4 and unsubstituted cobalt phthalocyanine, achieving 97.06% Rhodamine B degradation in 20 min. Furthermore, the poly-CoPc proves to be the most effective, with a degradation efficiency of 69.94% for tap water and 95.76% for seawater, producing predominantly 1O2. These results position poly-CoPc as a promising PMS activator for environmental treatment that surpasses metal oxide derivatives in terms of activity and properties.
