Although metal single atom catalysts (SAC) have been demonstrated to be effective in heterogeneous catalysis, establishing a scalable and cost-effective SAC support system remains an important challenge. Here, innovative ways to create materials that are entirely distinct from their parent characteristics for wastewater treatment and environmental challenges are proposed. Series of different molar ratio of Ag (0.01, 0.02, 0.03 and 0.04 wt%) were assigned to prepare Ag@CPAN composite and observe its impact application on photocatalytic degradation of 4-nitrophenol (4-NP) assisted by peroxymonosulfate (PMS) under visible light irradiation. The morphology and composition of the synthesized Ag@CPAN was characterized using a range of techniques. Several parameters were investigated that could influence degradation efficiency, including PMS concentration, solution pH, catalyst dosage, and initial 4-NP concentration. Under visible light irradiation, Ag@CPAN shows excellent photocatalytic performance of 4-NP, methylene blue, methyl red and RhB degradation. Ag@CPAN elucidates excellent catalytic performance while maintaining high stability up to 6 successive cycles and this backwards to synergistically effect between CPAN and Ag. Furthermore, provides an easy way to prepare a variety of SAC, and it is easily scalable with significant potential in catalytic applications.

Water pollution caused by water-immiscible pollutants such as BTXs has become a major concern for researchers in recent years. This study presents the synthesis of a hydrophobic photocatalyst, Ag-CuPc-ZnO/Silica Aerogel, prepared using sol-gel and impregnation methods for the degradation of oating benzene. The effect of different percentages of Ag on the photocatalyst performance was studied, and the optimal sample was tested in rectangular and cylindrical photoreactors. The physicochemical properties of the hydrophobic photocatalyst were analyzed using XRD, FESEM, FTIR, BET/BJH, PL, contact angle, and UV-Vis DRS. Our analysis showed that decreasing nanoparticle size led to an increased speci c surface area and decreased pore diameter. DRS analysis demonstrated that increasing Ag content led to a decreased bandgap and increased light absorption in the visible light region with CuPc addition. PL analysis indicated a signi cant decrease in electron-hole recombination with 5% Ag and con rms the e cient charge separation. The 5% wt. Ag sample achieved highest benzene photodegradation e ciency, while the rectangular photoreactor outperformed with superior degradation rates, STY, PSTY, and QY due to uniform light distribution and improved illumination. This study offers valuable insights on hydrophobic photocatalysts for degrading water-immiscible pollutants, emphasizing the need to optimize catalyst performance for e cient wastewater treatment.
