“…A graph was plotted between ln (C ∘ /C) and irradiation time and L–H model was fitted to the graph (Figure 8). The results reveal that photocatalytic degradation of NBB dye obeys the pseudo‐first‐order kinetics, while to analyses, the L–H model for the photocatalytic degradation of NBB dye was validated by regression coefficient R 2 of 0.99697 That is near to 1, and hence, we can say that catalytic degradation by Ag–CuO/GO composites follows the pseudo‐first‐order kinetics for NBB dye 58–61 …”

The significance of utilizing photocatalysts to degrade toxic dyes and microbes has grown in recent years. It has been demonstrated as a successful method for utilizing light through hybrid photocatalysts to break down harmful organic molecules. This study aims to investigate the potential applications of CuO–Ag/rGO nanocomposites in environmental remediation. The nanocomposites were synthesized by incorporating Ag and CuO nanoparticles onto rGO nanosheets via hydrothermal method. The nanocomposites that resulted were thoroughly characterized using various analytical techniques to determine their chemical structure, morphology, crystallinity, and photocatalytic application. The degradation efficiency of naphthol black blue (NBB) dye under visible light irradiation was used to assess the photocatalytic performance of the nanocomposites. It was revealed that 80.2%, 90.3%, and 97.3% of NBB dye degraded as a result of enhanced photocatalytic activity of synthesized CuO–Ag/rGO. The research provides valuable insights into the design and development of advanced nanomaterials for efficient and sustainable wastewater treatment applications.

“…[18,20,21] Hence, the appearance of magnetite Fe 3 O 4 with low toxicity and high surface area can solve this issue by easily separating under an external magnetic field. [22] Aabid Hussain Bhat et al proposed the Fe 3 O 4 /ZnO photocatalyst can easily be separated from the solution by using a bar magnetic. Moreover, the photocatalytic efficiency remained after undergoing four cycles of recycling, which is much better than the bare ZnO.…”

The utilization of metals and metal oxides as photocatalysts is a common method for treating dye contamination. Titanium dioxide nanoparticles (TNPs) are well known for their effectiveness as a photocatalyst in ultraviolet regions, while the inclusion of silver nanoparticles (AgNPs) can improve the photocatalytic properties of the nanocomposite materials in visible light. However, the TNPs and AgNPs are difficult to collect for reuse in water treatment due to their limited dispersion. Henceforth, this work recommended a novel photocatalyst based on hydrotalcite Mg−Al, magnetic Fe3O4 nanoparticles (FNPs), AgNPs, and TNPs prepared using the co‐precipitation method. Additionally, organic silane was first time used as a coupling agent to combine the components together. Consequently, the obtained products were applied for the degradation of methylene blue (MB) under natural sunlight. The characteristics of the synthesized nanocomposites were determined using infrared spectroscopy, vibrating‐sample magnetometer, X‐ray diffraction, dynamic light scattering, and scanning electron microscopy methods. The degradability of MB under sunlight was investigated using ultraviolet‐visible method. Moreover, the antibacterial activity and cytotoxicity of these nanocomposites has been tested and discussed.
