Herein, hexagonal/cubic ZnIn2S4 (ZIS) heterojunction catalysts were synthesized via a solvothermal method for the selective oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-diformylfuran (DFF). The results demonstrated that the constructed heterojunctions effectively promoted carrier separation. The optimal catalyst achieved an HMF conversion rate of 88.8% and a DFF yield of 86.6% within 1 h in the open air. X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) characterizations confirmed the successful fabrication of the composite phase structure and revealed a porous spherical morphology. Equivalent circuit fitting of electrochemical impedance spectroscopy (EIS) data indicated that the hexagonal/cubic heterojunctions possessed the lowest charge transfer resistance (Rct = 5825 Ω), which effectively reduced interfacial charge transfer resistance and accelerated the transport of photoinduced carriers. Radical quenching experiments and electron paramagnetic resonance (EPR) spectroscopy identified superoxide radicals (·O2−) as the primary reactive species. Meanwhile, density functional theory (DFT) calculations elucidated the formation of the built-in electric field and the charge transfer mechanism. This work’s construction of Type-II ZIS heterojunctions effectively addressed the issue of rapid carrier recombination in pristine ZIS materials, providing a feasible strategy for biomass valorization.","PeriodicalId":9794,"journal":{"name":"Catalysts","volume":"16 1","pages":"69-69"},"PeriodicalIF":0.0,"publicationDate":"2026-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.mdpi.com/2073-4344/16/1/69/pdf?version=1767785827","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147892009","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}

However, it is generally inactive in many catalytic reactions due to a lack of active sites. In this work, we report a new strategy, combining vapor-assisted synthesis with acid treatment to create abundant active sites in UiO-67(Zr), resulting from defects. The effects of some synthetic parameters were systematically investigated. As a result, an optimized material named UiO-67(Zr)-V-0.5FA-H, obtained by acid-treating UiO-67(Zr) and prepared with the addition of 0.5 mL formic acid via a vapor-assisted method, exhibited outstanding catalytic performance in the oxidation of dibenzothiophene (DBT), which can completely oxidize DBT in 9 min at 30 °C using H2O2 as the oxidant. The calculated turnover frequency reached 150.4 h−1, surpassing those of most reported Zr-MOFs catalysts. In addition, it is demonstrated that UiO-67(Zr)-V-0.5FA-H is a heterogeneous catalyst and can be reused without obvious activity loss.","PeriodicalId":9794,"journal":{"name":"Catalysts","volume":"16 1","pages":"70-70"},"PeriodicalIF":0.0,"publicationDate":"2026-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.mdpi.com/2073-4344/16/1/70/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147886193","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}

There is therefore a dire need for efficient methods of tetracycline removal. To this end, we constructed a series of super-small-sized BiVO4 composites with different loading amounts of 5 wt%, 10 wt%, 15 wt%, 20 wt%, and 25 wt% on SiO2 support by a hydrothermal–calcination method for efficient photocatalytic degradation of tetracycline. XRD and SEM results revealed that these composites all exhibited good crystallinity and well-dispersed morphologies. Particularly, the 20 wt% BiVO4@SiO2 of this series of composites showed superior photocatalytic performance, with 84.1% efficiency in tetracycline degradation, higher than any of its counterparts. This can be explained by its wide light-absorption range and high charge-separation efficiency, as confirmed by UV-Vis absorption spectra and quenched fluorescence spectra. This work offers a new method for the design and construction of tetracycline degradation photocatalysts.","PeriodicalId":9794,"journal":{"name":"Catalysts","volume":"16 1","pages":"63-63"},"PeriodicalIF":0.0,"publicationDate":"2026-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.mdpi.com/2073-4344/16/1/63/pdf?version=1767616257","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147906807","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 study, shape-specific CeO2 nanocrystals (nanorods, nanocubes, and nanoparticles) were successfully synthesized and employed as catalysts to study the structure-dependent behavior and reaction mechanism for one-step CO2 conversion to diethyl carbonate (DEC). Among the three catalysts, CeO2 nanorods (Ce-NR) exhibited the best catalytic activity in the synthesis of DEC from CO2 compared with CeO2 nanocubes (Ce-NC) and nanoparticles (Ce-NP), which achieved the DEC production of 1.32 mmolDEC/gcat at 423 K and 5 MPa for 4 h. Comprehensive characterization further confirmed the enhanced activity of Ce-NR originated from the morphology effect, particularly the promotion of oxygen vacancies and Ce3+ species, which promoted reaction activity. Furthermore, the Ce-NR catalyst almost retained 1.32 mmolDEC/gcat DEC production of its initial activity after four cycles, underscoring its exceptional stability and promising industrial scalability. These findings provide fundamental insights to guide the rational design of efficient catalysts for CO2 activation and other critical transformations.","PeriodicalId":9794,"journal":{"name":"Catalysts","volume":"16 1","pages":"58-58"},"PeriodicalIF":0.0,"publicationDate":"2026-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.mdpi.com/2073-4344/16/1/58/pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147910168","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}

Currently, it is produced through the reaction of alkaline metallic acetylides and acetone, requiring expensive raw material and harsh reaction conditions.

Nucleophilic reactivity of CaC2 with acetone can be regulated by the activating effect of the ball mill, an appropriate activator, and a proton donor. High yield of MB (~94%) was obtained under synergistic action of TBAF·3H2O and acetylene, which represents a facile synthesis process of MB under mild conditions. MB exhibits good defoaming performance, and 2,7-dimethyl-3,5-octadiyn-2,7-diol is more promising, being an excellent non-ionic defoamer.

However, catalysts in the powder form usually suffered from the strong tendency to agglomerate and the intricate operation for recycling, which significantly limited their practical application. In comparison, monolithic catalysts with their high macroscopic operability and recoverability as well as impressive specific surface area have attracted tremendous attention in recent years. To address these issues, a monolithic Fe-based catalyst was prepared via in situ synthesis, using nickel–iron foam (NFF) as the substrate with cobalt (Co) incorporation. XPS analysis showed that Co doping enhanced the synergistic interaction among Fe, Ni, and Co, accelerating the redox cycle among species, thus improving electron transfer and laying a kinetic foundation for efficient peroxymonosulfate (PMS) activation. Quenching experiments and EPR indicated singlet oxygen (1O2) as the main reactive species; Co doping shifted the degradation pathway from radicals to non-radicals. Under optimized conditions (PMS: 0.08 mmol/L; catalyst: 1 cm2; initial Chlortetracycline (CTC): 50 mg/L), 95.7% CTC degradation was achieved within 60 min, and efficiency only dropped to 90.5% after 5 cycles.
