“…A possible way to produce SO 4 •– from polymer-based TiO 2 photocatalysts, in addition to its activation in visible region, is the addition of oxidants like peroxymonosulfate (PMS) and persulfate (PS) to the system. Both PMS (HSO 5 – ) and PS (S 2 O 8 2– ) under effective irradiance (UV or heat) result in the formation of reactive radical species according to reactions and , respectively To the best of our knowledge, there has been a limited research on the oxidation mechanism of FQs by SO 4 •– , when oxidants were added to polymer-based immobilized TiO 2 /Ti films for photocatalysis under solar light irradiation.…”

This study is focused on the synthesis of a solar light driven novel poly(vinyl alcohol) (PVA)-assisted TiO 2 /Ti film via a facile one pot hydrothermal technique and then its photocatalytic applications by adding with peroxymonosulfate (PMS) for efficient degradation of ciprofloxacin (CIP). The key hydrothermal synthesis parameters like PVA-content, hydrothermal time (H T ), and pH were optimized. The best photocatalytic performance of the synthesized material was observed when prepared with the conditions of PVA = 8 mg, H T = 3 h, and pH = 2.62. Results showed that 98.3% of CIP was degraded within 60 min by PVA-assisted TiO 2 /Ti film with 0.5 mM PMS added, compared to 89.38% and 88.86% degradation with 0.5 mM persulfate (PS) and 0.5 mM hydrogen peroxide (H 2 O 2 ), respectively. The photocatalytic degradation of CIP by PVA-assisted TiO 2 /Ti film with PMS added was dependent on the [PMS] 0 and increased with increase in [PMS] 0 . The k app values at [PMS] 0 of 0.2, 0.5, 0.8, and 1.0 mM were 0.029, 0.0582, 0.068, and 0.128 min −1 , respectively. The photocatalytic degradation of CIP by PVA-assisted TiO 2 /Ti film with PMS added under solar light irradiation was highly dependent on the [pH] 0 as well as on the presence of coexisting anions like HCO 3 − , CO 3 2− , NO 2 − , Cl − , and SO 4 2− . Natural organic matter (NOM) retarded the photocatalytic degradation of CIP by PVA-assisted TiO 2 /Ti film with PMS added under solar light irradiation due to its strong scavenging ability toward • OH and SO 4 •−. The photocatalytic degradation of CIP by as-prepared photocatalyst under solar light irradiation was higher in Milli-Q water (k app = 0.0582 min −1 ) than tap water (k app = 0.0342 min −1 ) followed by river water (k app = 0.0259 min −1 ) and then synthetic wastewater (k app = 0.0212 min −1 ). The degradation products of CIP were investigated by UPLC-MS/MS, and accordingly degradation pathways were proposed. Moreover, the mineralization, ecotoxicity, and cyclic photocatalytic stability of the as-prepared photocatalyst were also investigated. These findings suggest that as-prepared PVA-assisted TiO 2 /Ti film with PMS added is a promising alternative for the treatment of wastewater containing antibiotics.

Recycling the Cathode Scrap of Spent Lithium-Ion Batteries as an Easily Recoverable Peroxymonosulfate Catalyst with Enhanced Catalytic Performance

The cathode in spent lithium-ion batteries (LIBs) has intrinsic properties and a unique sandwich-like structure and contains transition metals. Moreover, the transition metal-based catalysts frequently used in sulfate radical-based advance oxidation processes (SR-AOPs) entail a complex synthesis process, expensive mass production, and difficult separation and recovery. Here, we propose that a cathode scrap from spent LIBs can be directly recycled as stable and reusable SR-AOP catalysts. Compared with pristine LiMn 2 O 4 , the catalytic performance of the recycled active LiMn 2 O 4 component was enhanced by the prolonged lithiation/ delithiation cycles in situ. As a result, the cathode scrap shows high efficiency for peroxymonosulfate (PMS) activation, and the orthophenylphenol (OPP) degradation still reached 94.8% after 10 cycles. Multiple important properties of the recycled cathode scrap, such as the oxidation state, surface oxygen species, pore structure, and structure factors, were investigated in details. The pore in the coating further offers the chances for PMS to efficiently make contact with the interior active LiMn 2 O 4 and allow for the aqueous solution to diffuse to the interior Al foil, caused subsequently by the redox reaction of the Al foil. The synergistic effect between the Al foil and LiMn 2 O 4 -containing coating promotes the conversion of Mn(IV) to Mn(III) and electron transfer. The strong adhesion between the LiMn 2 O 4 -containing coating and Al foil through the binder enhances catalyst stability and endow the cathode scrap catalyst with easily recoverable characteristics. This work offers an attractive method for the recycling of spent LIBs and development of catalysts in SR-AOPs.

“…These findings presumably indicate that due to rapid corrosion and surface coverage of ZVA at pH = 3.0, poor model pollutant removals were achieved at pH = 3.0 [23,41,47,48]. In another study, 4 mg/L Al release was reported for Triton X-45 degradation with ZVA/PS under practically identical reaction conditions [60]. Al release rates increased by one order of magnitude when the reaction pH was decreased from 3.0 to 1.5.…”

Treatment of industrial contaminants with zero-valent iron- and zero-valent aluminium- activated persulfate: a case study with 3,5-dichlorophenol and 2,4-dichloroaniline

et al. 2021

Zero-valent iron (ZVI)- and zero-valent aluminium (ZVA)-activated persulfate (PS) oxidation procedure was applied to remove the industrial pollutants 3,5-dichlorophenol (3,5-DCP; 12.27 µM) and 2,4-dichloroaniline (2,4-DCA; 12.34 µM) from aqueous solutions. The effects of PS concentration and pH were investigated to optimize heterogeneous treatment systems. Negligible removals were obtained for both pollutants by individual applications of nanoparticles (1 g/L) and PS (1.00 mM). PS activation with ZVI resulted in 59% (1.00 mM PS; 1 g/L ZVI; pH 5.0; 120 min) and 100% (0.75 mM PS; 1 g/L ZVI; pH 5.0; 80 min) 3,5-DCP and 2,4-DCA removals, respectively. The ZVA/PS treatment system gave rise to only 31% 3,5-DCP (1.00 mM PS; 1 g/L ZVA; pH 3.0; 120 min) and 47% 2,4-DCA (0.25 mM PS; 1 g/L ZVA; pH 3.0; 120 min) removals. The pH decreases from 5.0 to 3.0 and from 3.0 to 1.5 enhanced contaminant removals for ZVI/PS and ZVA/PS treatments, respectively. Pollutant removal rates were in correlation with the consumption rates of the oxidants. Metal ion (Al, Fe) release increased in the presence of PS and with decreasing pH.
