Synthesis and Assessment of Novel Co-AAP-MOF as a Highly Effective and Reusable Photocatalyst for the Degradation of Organic Pollutants

Abstract In this study, a porous cobalt-based photocatalyst, Co-AAP-MOF, was fabricated via solvothermal process. The synthesized photocatalyst was characterized to examine its structural and morphological features using FTIR, UV–Vis, PXRD, SEM, EDX, and TEM. The photocatalytic efficacy of the synthesized catalyst was examined under xenon lamp irradiation utilizing Crystal Violet (CV) and Congo Red (CR) as model pollutants. Multiple experimental parameters, including dye concentrations, pH levels, exposure duration, and amount of Co-AAP-MOF, were tuned to attain optimal degradation results. Photocatalytic performance evaluations demonstrated that the photocatalyst could efficiently degrade the organic dyes with photocatalytic degradation efficiencies of 97% and 99% for CV and CR dyes, respectively. The bandgap energy of Co-AAP-MOF, as determined by UV–vis spectrum analysis, is 2.45 eV. These findings indicate that Co-AAP-MOF is an effective photocatalyst for the in-situ degradation of CR and CV dyes from wastewater, exhibiting exceptional photostability for over four cycles. Co-AAP-MOF inhibited AChE activity by 68.28 ± 0.02% and IC50-8.22 ± 0.07 µg/mL indicating its higher anti-Alzheimer’s activity.
