Synergistic effect of porphyrin and NiO in chitosan/graphene oxide aerogels for enhanced photocatalytic degradation of cationic and anionic dyes.

ABSTRACT: The need for clean water has driven the search towards better ways to remove pollutants from wastewater, especially dyes from industrial sources. In this study, we introduce a novel multifunctional aerogel composite CPGNiO(5%)PyP(1%), that brings together five carefully selected components: chitosan, polyvinyl alcohol, graphene oxide, nickel oxide nanoparticles, and a porphyrin-based photosensitizer. By combining these materials, we created a porous, light-responsive system that works exceptionally well under visible light. Using a range of techniques (FT-IR, XRD, SEM/TEM, UV-vis, and XPS), we confirmed the structure and interactions within the hybrid network. When tested against two common dyes, Victoria Blue R (cationic) and Reactive Black 5 (anionic), the composite achieved impressive r
