Here, the synergistic removal of NO and chlorobenzene was achieved through catalysis assisted dielectric barrier discharge (DBD) mechanism under different conditions. The experimental results suggested that the increase of specific energy density (SED) and the loading of CeO₂ strengthened the treatment of NO and chlorobenzene. A higher degradation efficiency of NO and a lower production rate of NO₂ were achieved after the introduction of chlorobenzene. The removal of chlorobenzene could also be benefited from this process, and the introduction of NO promoted CO₂ selectivity of chlorobenzene. The XPS and H₂-TPR analyses confirmed that the reaction between chlorobenzene and NO occurred by the assistance of Ce³⁺/Ce⁴⁺ redox cycle as well as the consumption and regeneration of chemically adsorbed oxygen. During the reaction, the oxygen vacancies (OVs) caused by plasma etching promote the redox cycle and alleviate the catalyst poisoning caused by chloride ions (Cl⁻). Furthermore, a comprehensive analysis of the resulting byproducts revealed phenol as the most significant intermediate in chlorobenzene degradation, while acetaldehyde emerged as the major product resulting from ring-opening processes of chlorobenzene. Utilizing chlorobenzene from flue gas subtly, this method presents a more sustainable alternative for NO reduction, showing promise for addressing industrial emission challenges.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"155 6","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144073623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Structural and morphological properties were investigated using XRD, SEM, BET, EDS, FTIR, and UV–DRS.

Scavenger tests confirmed photogenerated holes and hydroxyl radicals as primary reactive species. BiOCl-200-4 also retained 90.28% of its activity after five cycles, indicating good stability. Unlike previous studies, this work systematically optimizes synthesis parameters to control crystallinity, morphology, and facet exposure, achieving a dominant (001) orientation that improves photocatalytic efficiency.

Upon certain modification, Znln₂S₄ (ZIS) has been considered as a promising candidate for H₂ production via water splitting. In this study, non-metal doping and the formation of heterostructure were applied to synthesize Mo₂C (MC)/ZIS heterosystem and N-ZIS. Their H₂ evolution via water splitting was compared with TiO₂. After determining the optimal photocatalyst, both generations of total gases and individual gases (i.e., H₂ and CO₂) were maximized by studying different reaction conditions (i.e., photocatalyst concentration and type and dosage of sacrificial agent). Finally, the stability of the best photocatalyst at the optimal H₂ production conditions was investigated. Results show that the MC/ZIS was identified as the best photocatalyst. The optimal reaction conditions were determined to be: photocatalyst concentration of 0.015 wt%, methanol as the sacrificial agent, 20 vol% methanol dosage for 2 h reaction time, producing the highest evolution of total gases of 22,024 µmol/g_catalyst. It was also observed that the highest amount of H₂ evolution was obtained at 990 µmol/g_catalyst at 0.104 wt% concentration of photocatalyst and using 20 vol% methanol as a sacrificial agent for 2 h. For the stability of MC/ZIS, there were no considerable changes in the first two cycles. However, the amount of H₂ evolution was reduced by 26.78% after 3rd cycle.

However, its practical use is often hindered by issues such as low stability and reusability. In this study, CAT was effectively immobilized onto the onion inner epidermis (OIE) via adsorption and cross-linking techniques, aiming to improve its catalytic activity, stability and reusability. The optimization of the immobilization process was carried out by evaluating key factors, including CAT concentration, OIE quantity, adsorption duration, and cross-linker concentration. The immobilized CAT exhibited a significant improvement in thermal stability, retaining 50% activity at 60 °C compared to 30% for the free enzyme. Similarly, it displayed enhanced pH stability, maintaining 70% activity at pH 5.5 and pH 8.5, while the free enzyme retained only 50% and 60%, respectively. Kinetic studies revealed a higher V_max (2.26 × 10⁻⁴ µmol H₂O₂/min) and lower K_m (3.36 mM) for the immobilized enzyme, indicating improved catalytic efficiency and substrate affinity. The immobilized enzyme preserved 40% of its activity after 28 consecutive uses and retained 30% activity following 30 days of storage, demonstrating its long-term stability. This study demonstrates that immobilized CAT on OIE is a promising biocatalyst for agricultural and food industries, where it can be utilized for H₂O₂ detoxification, food preservation, and wastewater treatment. The use of OIE as a low-cost, natural carrier further supports the development of sustainable and eco-friendly biocatalytic systems for industrial applications.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"155 6","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144074156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conversely, the production processes of these materials, together with the selection of diverse nitrogen doping strategies and the underlying mechanisms, remain subjects requiring further investigation. This experiment employed the molten salt method for the synthesis of MXenes. This approach is beneficial as it effectively mitigates the influence of fluorine groups on the electrochemical characteristics of MXenes. A study was conducted on the effects of doping with two distinct nitrogen sources: urea and lithium nitride. The microstructures and electrochemical characteristics were analyzed to ascertain the most effective preparation and nitrogen doping methods. The Ti₃AlC₂ precursor was specifically etched with CoCl₂ in a eutectic salt solution of KCl and LiCl to produce Ti₃C₂. Subsequently, lithium nitride was selected as the nitrogen source, resulting in the synthesis of MXenes with enhanced hydrogen evolution reaction performance. The studied HER cathode material exhibited a distinctly defined layered structure with significantly increased interlayer gap. This led to an increased surface area and a higher density of active sites. The electrochemical test findings indicated an overpotential of 82 millivolts at a current density of 10 milliamperes per square centimeter, with a Tafel slope of 120.4 millivolts per degree. The electrochemical impedance spectroscopy (EIS) analysis revealed that the series resistance (Rs) is 1.571 Ω, indicating a low value. The charge transfer resistance (Rct) was measured at 78.56 Ω, corroborating the superior performance.

The overpotential of TNT/SnO₂/IrO_x at a current density of 10 mA cm^− 2 was 220 mV, which is 69 mV and 93 mV lower than that of directly loaded TNT/IrO_x (289 mV) and TNT/IrO₂ (313 mV), respectively.
