“…[197a] Inorganic glass membranes have also been studied in practical applications owing to their strong acid and alkali corrosion resistance, low cost, excellent mechanical ability, and facile synthesis. [200] Samy and co-workers designed a photocatalytic reactor by combining CNTs/MOF-808 and glass plates, and achieved excellent degradation of carbamazepine and diazinon. [201] Through the optimization of operation parameters, the effective removal (93%) of pollutants in the actual agrochemical wastewater can be maintained for a long duration.…”

State‐of‐the‐art Fenton‐like reactions are crucial in advanced oxidation processes (AOPs) for water purification. This review explores the latest advancements in heterogeneous metal‐based catalysts within AOPs, covering nanoparticles (NPs), single‐atom catalysts (SACs), and ultra‐small atom clusters. A distinct connection between the physical properties of these catalysts, such as size, degree of unsaturation, electronic structure, and oxidation state, and their impacts on catalytic behavior and efficacy in Fenton‐like reactions. In‐depth comparative analysis of metal NPs and SACs was conducted focusing on how particle size variations and metal‐support interactions affect oxidation species and pathways. The review highlights the cutting‐edge characterization techniques and theoretical calculations, indispensable for deciphering the complex electronic and structural characteristics of active sites in downsized metal particles. Additionally, the review underscores innovative strategies for immobilizing these catalysts onto membrane surfaces, offering a solution to the inherent challenges of powdered catalysts. Recent advances in pilot‐scale or engineering applications of Fenton‐like based devices have also been summarized for the first time. The paper concludes by charting new research directions, emphasizing advanced catalyst design, precise identification of reactive oxygen species, and in‐depth mechanistic studies. These efforts aim to enhance the application potential of nanotechnology‐based AOPs in real‐world wastewater treatment.This article is protected by copyright. All rights reserved

Photocatalysis with TiO2 semiconductors is one of several potential methods for removing Methylene Blue (MB) that is environmentally friendly, relatively cheap, and effective. The capability of TiO2 photocatalysts for degrading MB can be improved by modifying the morphology of TiO2 into nanotubes and adding anthocyanin sensitizers. The objective of this study was to investigate the effect of anthocyanin sensitizer addition for TiO2 nanotubes on MB removal using a combined process of electrocoagulation and photocatalysis. TiO2 nanotubes were prepared through an anodization method with a glycerol electrolyte containing NH4F of 0.5%w/v and water of 25%v/v. The cathode and anode used in the electrocoagulation process were 316 stainless steel and aluminum, respectively. The characteristics of the resulting TiO2 nanotubes were analyzed using SEM-EDX, UV–Vis DRS, and XRD analyses. The results showed that the electrocoagulation at a pH of 10 and a voltage of 50 volts resulted in an MB removal efficiency of 57.88%. In the photocatalysis process, sensitizer addition can increase the MB removal efficiency from 19.71% to 29.06%. Furthermore, a combined process of electrocoagulation and photocatalysis without and with sensitizer addition resulted in MB removal efficiencies of 59.66% and 64.30%, respectively.
