Abstract

ABSTRACT

In this study, N‐ZnO/g‐C
3
N
4
/GO nanocomposites were successfully fabricated via the coprecipitation method. Characteristics of synthesized photocatalysts were analyzed using FTIR, XRD, FESEM, EDX mapping, TEM, and PL. The photocatalytic performance of the synthesized nanoparticles was evaluated for the degradation of methylene blue (MB) under visible light. The N‐ZnO/g‐C
3
N
4
/GO nanocomposite exhibited significantly enhanced performance, achieving 91% MB degradation within 60 min, whereas pure ZnO degraded only 25.38% after 90 min. Incorporating the synthesized photocatalysts into the dynamic membrane had a significant effect on the rejection rate of MB and permeation flux. While the pure PES membrane rejected only 30% of MB, the self‐forming dynamic membrane (SFDM) and precoated dynamic membrane (PCDM) containing the nanocomposite achieved > 85% and ~98% degradation within 15 and 10 min, respectively. These results demonstrate a strong synergistic effect between the photocatalyst and the dynamic membrane, leading to substantially improved dye removal and permeation performance.
