“…Generally, the conditions such as temperature, pH, catalyst loading, and concentration of PS/PMS affect the removal rate of substances. For instance, the degradation efficiency of bisphenol A (BPA) was shown to increase gradually (in a linear relationship) from 46.7 to 66.4 to 76.8 to 96.4 and 99.0% with the PS concentrations increased from 7.4 to 15 to 22 to 30 and 35 mM (Xu et al, 2019). However, the degradation rate of ketoprofen (KET) increased from 69.4 to 97.3 to 100% when the pH gradually increased from 3 to 7 to 10, respectively (Feng et al, 2017).…”

“…Some of the latest literature published revealing the kinetic mechanisms of typical organic pollutants during SR-AOPs is presented in Table 4. Overall, the degradation processes of (1) typical EDCs (such as bisphenol A, bisphenol F, and tetrabromobisphenol A) (Ji et al, 2016b;Hammouda et al, 2018;Xu et al, 2019) and 2PPCPs (such as ketoprofen, ibuprofen, carbamazepine, etc.) (Feng et al, 2017;Wang et al, 2019;Guo et al, 2020) fit well with the pseudo-first-order kinetics.…”

“…Electron transfer is the predominant mechanism of the reaction between SO − 4 • and aromatic organics. Taking the SR-AOP degradation of, for example, ketoprofen (Feng et al, 2017), bisphenol F (Hammouda et al, 2018), and bisphenol A (Xu et al, 2019), the attack or destruction of the benzene ring by SO − 4 • might be the main reason for their degradation. By comparison, hydrogen abstraction could easily occur during SO − 4 • reaction with saturated organic compounds (e.g., alkanes, alcohols, organic acids, ethers, and esters) (Zhao et al, 2016).…”

High levels of toxic organic pollutants commonly detected during domestic/industrial wastewater treatment have been attracting research attention globally because they seriously threaten human health. Sulfate-radical-based advanced oxidation processes (SR-AOPs) have been successfully used in wastewater treatment, such as that containing antibiotics, pesticides, and persistent organic pollutants, for refractory contaminant degradation. This review summarizes activation methods, including physical, chemical, and other coupling approaches, for efficient generation of sulfate radicals and evaluates their applications and economic feasibility. The degradation behavior as well as the efficiency of the generated sulfate radicals of typical domestic and industrial wastewater treatment is investigated. The categories and characteristics of the intermediates are also evaluated. The role of sulfate radicals, their kinetic characteristics, and possible mechanisms for organic elimination are assessed. In the last section, current difficulties and future perspectives of SR-AOPs for wastewater treatment are summarized.

“…To conclude whether the elimination is associated with photocatalytic reaction instead of dye sensitization, colorless BPA and Cr 6+ were used as target pollutants. BPA, as a xenon-estrogen, is widely used in the production of various polymer materials [5]. Herein, BPA was chosen as the non-dye pollutants to evaluate the photocatalytic ability of various cloths (Fig.…”

The development of effective and reusable photocatalysts with broad-spectra activity has attracted attention. Herein, we have constructed n-TiO 2 /p-Ag 2 O junction on carbon fiber (CF) cloth as an efficient and recyclable photocatalyst. With CF cloth as the substrate, TiO 2 nanorods (length: 1-2 µm) are prepared by a hydrothermal process, and the in-situ growth of Ag 2 O nanoparticles (10-20 nm) is then realized by chemical bath deposition route. The flexible CF/TiO 2 /Ag 2 O cloth (area: 4 × 4 cm 2) shows a broad and strong photo-absorption (200-1000 nm). Under the illumination of visible-light (λ > 400 nm), CF/ TiO 2 /Ag 2 O cloth can efficiently eliminate 99.2% rhodamine B (RhB), 99.4% acid orange 7 (AO7), 87.6% bisphenol A (BPA), and 89.5% hexavalent chromium (Cr 6+) in 100 min, superior to CF/Ag 2 O cloth (83.5% RhB, 60.0% AO7, 31.2% BPA and 41.8% Cr 6+). In particular, under the NIR-light illumination (980 nm laser), CF/TiO 2 /Ag 2 O cloth can remove 70.9% AO7 and 60.0% Cr 6+ in 100 min, which are significantly higher than those by CF/Ag 2 O cloth (19.8% AO7 and 18.9% Cr 6+). In addition, CF/TiO 2 /Ag 2 O cloth (diameter: 10 cm), as a filter-membrane, can effectively wipe off 94.4% flowing RhB solution (rate: ~ 1 L h − 1) at 6th filtering/degrading grade. Thus, CF/TiO 2 /Ag 2 O cloth can be used as a Vis-NIR-responded filtermembrane-shaped photocatalyst with high-efficiency for purifying wastewater.

BACKGROUND During the last few years, perovskite materials have been widely investigated as catalysts for peroxymonosulfate (PMS) and persulfate (PS) activation in advanced oxidation processes (AOPs) for the degradation of various pollutants. In the present work, a sequence of LaCoxNi1‐xO3 (x = 0, 0.25, 0.50, 0.75, 1) perovskite materials was synthesized by sol–gel method using glycolic acid ethoxylate lauryl ether anionic surfactant as soft template. RESULTS The physicochemical properties of the prepared materials were studied by several techniques, such as N2 porosimetry, Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy (ATR FT‐IR), X‐Ray Diffraction (XRD), X‐Ray Fluorescence (XRF), X‐Ray Photoelectron Spectroscopy (XPS), and Scanning Electron Microscopy (SEM). The catalytic activity towards phenolic degradation by persulfate (PS) activation was studied and, based on the reaction rate constant values, the order of increasing catalytic performance was LaCoO3 < LaCo0.75Ni0.25O3 < LaCo0.5Ni0.5O3 < LaCo0.25Ni0.75O3 < LaNiO3. The perovskites that exhibited optimal catalytic activity (i.e., LaCo0.25Ni0.75O3 and LaNiO3) were further evaluated for their stability, reusability, and catalytic mechanism. Finally, according to scavenging experiments, 1O2, SO4•‐, and •OH generated with 1O2 played the dominant role in phenolic degradation. CONCLUSION The substitution of Co by Ni in LaCoO3 materials showed an increase in their catalytic activity towards phenolic oxidation through persulfate activation. The results provide insights into the characterization and mechanisms of novel perovskite catalysts and their applications for the removal of organic pollutants by advanced oxidation processes (AOPs). Further studies improving the stability and reusability of the catalysts should be conducted. © 2022 Society of Chemical Industry (SCI).
