The photocatalysts were characterized using XRD, SEM-EDS, and BET. The optimal performance was observed with a 0.5% Ag-TiO₂ concentration, achieving a degradation efficiency of 59% under 200 W UV light over 180 min of treatment. The effect of photocatalyst loading was then optimized, followed by an investigation of the synergistic effects of photocatalysis (PC) coupled with hydrogen peroxide (H₂O₂). The highest degradation efficiency of 94% was achieved at 0.01% v/v H₂O₂ with a synergistic coefficient of 24, within 60 min. Further enhancement was observed when combining PC, H₂O₂, and hydrodynamic cavitation (HC), achieving complete degradation of MO in just 3 min (1.5 passes) with a high synergistic coefficient of 42. The degradation process was represented as pseudo-first-order kinetics for PC alone and combined with H₂O₂, and a per-pass degradation model for HC. The impact of various scavengers on the photocatalytic process was examined, highlighting the crucial roles of hydroxyl radicals (•OH) and photogenerated holes (h⁺) in the degradation mechanism. The influence of anions and the water matrix on the reactive oxygen species (ROS) generation and efficiency, as well as the environmental fate of Ag-TiO₂ catalysts, is also discussed. This research underscores the importance of optimizing doped photocatalyst composition and operational conditions to maximize pollutant degradation efficiency, demonstrating significant advancements in advanced oxidation processes through synergy.</p>","PeriodicalId":22,"journal":{"name":"ACS Omega","volume":"10 21","pages":"21377–21390 21377–21390"},"PeriodicalIF":3.7,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsomega.5c00034","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144194164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, tetraphenylethene and triphenylamine were selected as the structural cores for constructing optical probes for Cu²⁺. The tetraphenylethene and triphenylamine groups were bonded to a ═N–N═ group, forming a probe structure. Additionally, there were two −OH groups near the ═N–N═ group, offering additional recognition sites to improve the sensing selectivity. The discussion covered the geometry, electronic transitions, optophysical properties, and spectroscopic behaviors toward copper(II). It was concluded that the −OH group improved the sensing selectivity by increasing the affinity between the probe and Cu²⁺. The electron donors in these dyes compromised the sensing selectivity but decreased the emission recovery time. The optimal probe (P1) decreased its emission quantum from 7.8 to 0.2% by Cu²⁺ and then recovered to 7.4% by CO within 529 s, with its emission spectrum well recovered. The emission recovery of P1 was sensitive to temperature, and a high temperature (40 °C) helped P1 emission recovery. The recognition principle was yielding a nonemissive adduct between the probe and Cu²⁺ with a complexation constant of 6.25 × 10⁷ L/mol. The sensing mechanism toward Cu²⁺ was revealed as the combination of static and dynamic sensing with Job’s plot, lifetime comparison, ¹H NMR, and IR comparison. The other four probes, having no −OH groups, exhibited poor sensing selectivity and lower emission recovery values.

Although previous studies have primarily examined the characteristics of organic matter, basin depositional environments, and individual geochemical parameters, detailed analyses of depositional microfacies remain limited. Furthermore, the integration of geochemical analyses with sedimentological characteristics has been insufficient, leading to a limited understanding of the factors controlling the organic matter enrichment in transitional shale. This study focuses on the Taiyuan Formation in the Carboniferous-Permian Palougou section of the Ordos Basin. By employing an integrated approach comprising petrological and sedimentological analyses, major and trace element geochemistry, total organic carbon (TOC) content measurements, kerogen maceral identification, and scanning electron microscopy (SEM), we reconstructed four critical paleoenvironmental parameters: depositional environment, paleosalinity, paleoredox, and paleoproductivity. The findings provide insights into paleoenvironmental controls of the mechanisms of organic matter enrichment in transitional shale. Petrological and sedimentological data reveal seven distinct sedimentary microfacies in the transitional shale: upper delta plain flood lake, lower delta plain interdistributary bay, supratidal wetland, supratidal dryland, and intertidal, subtidal, and clastic offshore environments. A depositional model encompassing shallow-water delta, tidal flat, and offshore environments has been established, and it is found that the sedimentary environments in the study area responded to high-latitude glacial cycles. The evolution of the sedimentary environment, driven by late Paleozoic glaciations, is the primary factor influencing organic matter enrichment in the transitional shales of the study area, as it directly affects both the source and preservation conditions of shale organic matter. Specifically, flood lake and supratidal wetland environments are identified as the most favorable for organic matter enrichment, followed by the distributary bay and subtidal environments.

Therefore, the effective removal of Cl^– from the desulfurization of ionic liquids is of great significance. This paper discusses the use of modified 717 resin for the removal of Cl^– from a desulfurization ionic liquid. First, the adsorption equilibrium, adsorption thermodynamics, and adsorption kinetics of the modified 717 resin for Cl^– were studied. The adsorption isotherm conforms to the Langmuir model, with an adsorption enthalpy of 1.971 kJ mol^–1, indicating that the process is a monolayer endothermic reaction. The adsorption kinetics follow a pseudo-second-order kinetic model, suggesting that the adsorption rate is controlled by chemical adsorption. Second, through dynamic adsorption experiments, it was determined that the optimal process parameters for Cl^– removal were: liquid flow rate of 2 mL/min, bed height of 10 cm, initial Cl^– concentration of 2300 mg/L, and reaction temperature of 45 °C. The dynamic behavior of the modified 717 resin in adsorbing Cl^– conforms to the Thomas model and the Yoon-Nelson model. Then, the equilibrium adsorption capacity of Cl^– of the modified 717 resin decreased by only 1.42 mg/g after five regeneration experiments, indicating that the resin has good renewability. Finally, the modified 717 resin removes Cl^– from the actual desulfurization ionic liquid with good results.

In this study, performance comparisons between two industrially available biobased itaconate elastomers (BIE) and commercial solution-polymerized styrene–butadiene rubber (SSBR) indicated that BIE/silica exhibited higher dry sliding/rolling friction coefficients. It is attributed to the superior frictional damping efficiency of side ester groups in BIE compared to styrene and vinyl moieties in SSBR. In addition, to address the inherent challenges of low cross-linking efficiency and network density caused by the molecular structure of BIE, an innovative dual cross-linking system was developed by combining amino-functionalized polysulfide (PDAS) with sulfur. This system simultaneously activated cross-linking reactions at both double bonds and diester groups, enabling efficient vulcanization of the elastomer. Systematic investigations were conducted to characterize the effects of the PDAS dosage on cross-linking density, filler dispersion, and dynamic/static mechanical properties. Validated with a high-performance tire formulation, BIE/silica with the dual-cross-linked system had reached the same level as SSBR/silica in terms of cross-linking density, mechanical properties (tensile strength: 17.4 MPa, elongation at break: 422%), and Akron abrasion resistance. It also showed balanced dynamic mechanical properties (tan δ = 0.744 at 0 °C and tan δ = 0.092 at 60 °C).
