“…The corresponding rate constants (k) and the squared correlation coefficients (R 2 ) are summarized in Table 2. The highest reaction rate constant was obtained when using the coated membrane under UV/H 2 O 2 , confirming that photo-Fenton reaction on the membrane was the primary factor for the enhanced degradation of SMX [24,25]. Figure 2b shows the TOC changes in the SMX solution under different reaction conditions.…”

“…A UVL 214-Watt lamp (Analytikjena Company, Beverly, MA, USA) provides a monochromatic UV 254 irradiation of 401 µW•cm −2 on the surface of the α-FeOOH-coated membrane. More detailed illustration of the photocatalytic membrane filtration was reported previously [24,25].…”

“…Moreover, combination of AOPs and membrane filtration has gained a great deal of attention recently as AOPs show synergistic roles in membrane filtration by enhancing pollutant degradation [18,19], improving filtration performance [20], and mitigating membrane fouling [21][22][23]. For example, our previous work [24,25] and a few others [26,27], heterogeneous photo-Fenton reaction was coupled with ceramic membrane filtration and increased the removal efficiency of 55 ± 5% and surface foulants (e.g., BSA and humic acid). Yang Guo developed a novel catalytic ceramic membrane with a coating layer of CuMn 2 O 4 particles that increased ozonation and filtration performances.…”

“…This improvement was ascribed to the surface-catalytic reactions between ozone and CuMn 2 O 4 particles that enhanced the ozone self-decompose to generate. Other reactive membrane systems (e.g., microwave-enhanced membrane filtration [29], photocatalytic ceramic membrane [24,25,[30][31][32], and electrochemical ceramic membrane [33][34][35][36]) were recently tested for their removal capabilities of various micropollutants including 1,4-dioxane, dyes, and drugs.…”

Pharmaceutical residuals are increasingly detected in natural waters, which made great threat to the health of the public. This study evaluated the utility of the photo-Fenton ceramic membrane filtration toward the removal and degradation of sulfamethoxazole (SMX) as a model recalcitrant micropollutant. The photo-Fenton catalyst Goethite (α-FeOOH) was coated on planar ceramic membranes as we reported previously. The removal of SMX in both simulated and real toilet wastewater were assessed by filtering the feed solutions with/without H2O2 and UV irradiation. The SMX degradation rate reached 87% and 92% respectively in the presence of UV/H2O2 for the original toilet wastewater (0.8 ± 0.05 ppb) and toilet wastewater with a spiked SMX concentration of 100 ppb. The mineralization and degradation by-products were both assessed under different degradation conditions to achieve deeper insight into the degradation mechanisms during this photo-Fenton reactive membrane filtration. Results showed that a negligible removal rate (e.g., 3%) of SMX was obtained when only filtering the feed solution through uncoated or catalyst-coated membranes. However, the removal rates of SMX were significantly increased to 67% (no H2O2) and 90% (with H2O2) under UV irradiation, respectively, confirming that photo-Fenton reactions played the key role in the degradation/mineralization process. The highest apparent quantum yield (AQY) reached up to approximately 27% when the H2O2 was 10 mmol·L−1 and UV254 intensity was 100 μW·cm−2. This study lays the groundwork for reactive membrane filtration to tackle the issues from micropollution.

“…This is well-explained by the fact that materials that have smaller size (crystallite size) are more reactive and exhibit enhanced physicochemical properties due to the larger exposed surface area. [16][17][18] This positions the nano-synthesized materials as better options compared to their bulky counterparts. Nanomaterials are thus dened as particles with at least one dimension on the nanoscale (1-100 nm), which are purposely structured on this scale so that their properties can be exploited according to their dimensions.…”

The Fenton reaction refers to the reaction in which ferrous ions (Fe2+) produce hydroxyl radicals and other reactive oxidizing substances by decomposing hydrogen peroxide (H2O2). This paper reviews the mechanism, application system, and materials employed in the Fenton reaction including conventional homogeneous and non‐homogeneous Fenton reactions as well as photo‐, electrically‐, ultrasonically‐, and piezoelectrically‐triggered Fenton reactions, and summarizes the applications in the degradation of soil oil pollutions, landfill leachate, textile wastewater, and antibiotics from a practical point of view. The mineralization paths of typical pollutant are elucidated with relevant case studies. The paper concludes with a summary and outlook of the further development of Fenton‐like reactions.
