“…Despite the high activity of homogeneous catalysts, the performance of any catalyst dissolved in water implies that ultimately the catalyst itself will become a secondary pollutant. Using solid, heterogeneous, recyclable, and waste-derived catalysts is crucial for preventing the generation of secondary pollutants 31 . These offer benefits like low toxicity, high efficiency, selectivity, short reaction times, and mild conditions for degrading dyes and pollutants.…”

Persistent environmental colored compounds, resistant to biodegradation, accumulate and harm eco-systems. Developing effective methods to break down these pollutants is crucial. This study introduces Ag-MIL-101 (Ag-MIL-101) as a composite and reusable catalyst that efficiently degrades specific colored organic pollutants (COPs) like Methylene blue (MB), 4-Nitrophenol (4-NP), and 4-Nitroaniline (4-NA) using sodium borohydride at room temperature. The MIL-101 was synthesized using Terephthalic acid (TPA) derived from the degradation of Polyethylene Terephthalate (PET) plastic waste, with the assistance of zinc chloride. To further investigation, the kinetics of degradation reaction was studied under optimized conditions in the presence of Ag-MIL-101 as catalyst. Our results demonstrated the remarkable efficiency of the degradation process, with over 93% degradation achieved within just 8 min. The catalyst was characterized using FTIR, XRD, FESEM, and TEM. In this study, the average particle size of Ag-MIL-101 was determined using SEM and XRD analysis. These methods allow us to accurately and precisely determine the particle size. We determined the reaction rate constants for the degradation of each COP using a pseudo first-order kinetic equation, with values of 0.585, 0.597 and 0.302 min−1 for MB, 4-NP, and 4-NA, respectively. We also evaluated the recyclability of the catalyst and found that it could be reused for up to three cycles with only a slight decrease in efficiency (10–15%). Overall, our findings highlight the promising application of Ag-MIL-101 as an effective catalyst for the degradation of COPs, emphasizing the importance of optimizing reaction conditions to achieve enhanced efficiency.

In the present era, a significant amount of research work is focused on eco‐friendly technologies and advanced liquid waste management strategies. Notably, industries primarily textile chemical processing sectors which are inherently involved with a wide array of dye usage, are integral focal points for these transformative endeavors. Against this backdrop, we have successfully synthesized an innovative photocatalyst with a remarkable capability to rapidly neutralize deleterious dyes within an astonishingly brief span of 4–6 minutes, facilitated by exposure to UV‐visible irradiation. Briefly, our approach entails the hydrothermal synthesis of a composite material based on zinc stannate (ZnSnO3) nanoparticles integrated with the copper‐decorated metal‐organic framework (ZnSnO3@H3BTC‐Cu MOF). The resulting material is endowed with a crystalline and porous architecture that confers a specific surface area measuring 437.25 m2 g−1, a value surpassing that of unadorned nano‐ZnSnO3 by a factor of approximately 15 (29.11 m2 g−1). Noteworthy beyond its enhanced surface features, the newly synthesized ZnSnO3@H3BTC−Cu MOF exhibits remarkable antibacterial efficacy against gram‐positiveS. aureusand gram‐negativeE. colibacterial strains. It might also be considered a stable photocatalyst to be used in wastewater treatment, as evidenced by the photoelectrochemical and photocatalytic investigation.
