“…The effectiveness of the photocatalysis procedure for the synthesized material was tested under both acidic and basic pH conditions, with the degradation performance reaching up to 92 % at the final dye concentration. [51] Similarly, by assessing the photocatalytic degradation efficiency of maxilon blue dye under UV light irradiation, Hashim et al [52] described the photocatalytic action of the (Ag, Pd)/ZnO NPs. The experimental findings demonstrated that increasing the Ag and Pd doping improved the photocatalytic efficacy of the ZnO NPs.…”

“…When compared to Ag/ZnO or Pd/ZnO NPs, the (Ag, Pd)/ZnO NPs showed better photocatalytic effectiveness, which may be explained by the transfer of photogenerated e À from ZnO to Pd and Ag, lowering the likelihood of recombination and photoluminescence intensity. [52] The same author investigated the degradation of MXB GRL dye pollutants under UV light irradiation. According to these findings, the synthesized ZnO/Fe 2 O 3 nanocomposite exhibited good photocatalytic activity when exposed to UV light.…”

The most essential task in the twenty‐first century is to fight the alarming growing pollution in the aquatic body in which effluent of one of the most colouring dye categories called maxilon dye is a major contributor. This review thus specifically focuses on the use of nanoparticles (NPs) for photocatalytic degradation of maxilon dye contaminants in water bodies. The work empirically presented the performance evaluation of NPs in degrading maxilon dyes under light irradiation alongside the underlying operational photocatalytic degradation mechanism. The stability of NPs was also critically analyzed by looking at the regenerability and reusability of expended NPs. From the study, it was discovered that ⋅OH and O2⋅ played a vital role in the genesis of the oxidizing capacity of NPs for the photocatalytic breakdown of maxilon dye. Moreover, it was found that the degradation performance of most NPs is greater than 80 % and the shortest degradation period is < 1 hour with pseudo‐first‐order (PFO) being the most common kinetic best‐fit to describe the adsorption process that occurred shortly before and during the degradation operation. At the end, knowledge gaps were identified in the area of regenerability, the lifecycle analyses of nano‐photocatalyst fabrication and utilization, cost analysis for industrial scale‐up, maxilon dye ecotoxicological study, and degradation pathways. The findings of this study can open up insightful innovation for readers and industries that are interested in pursuing zero water insecurity.

“…Recently photocatalysts based on Ag have been developed as effective photocatalysts for pollutant degradation [13,14].Although both materials show great potential, due to recombination of the e -/h + pair [15][16][17], they do not operate with high photocatalytic e ciency. The goal of this research work was to use the catalyst Ag-ZnO/Fe 2 V 4 O 13 to study the mineralization of MO dye by photodegradation using a technique different from the approaches mentioned above.…”

Novel Ag encapsulated nanocompositesZnO/Fe2V4O13 (AZF) were synthesized with various wt% of the silver (from 1.0 to 2.5 wt% of Ag) by photo-deposition method using UV-A light. The nanostructure of the AZF was explored by various characterization techniques. Surface functional group was confirmed by FT-IR spectra, the crystalline nature of the material revealed by XRD patterns. Furthermore, surface morphology and optical properties of the composites were analyzed by SEM, HR-TEM UV-DRS and PL respectively. The photoactivity was tested against Methyl Orange (MO) degradation under UV light. The stability of the catalyst was confirmed by reusability measurements. Suitable degradation pathway was proposed based on intermediates obtained during degradation analyzed by GC-MS. Trapping experiments confirmed that super oxide radical anion (O2·–) has been consider as a most active species for this degradation process. Mineralization is confirmed by measurements of chemical oxygen demand (COD).
