However, there are few studies on preparing stable large-sized one-dimensional Fe3O4 magnetic nanochains structure by a simple self-assembly method, and its application scope needs to be expanded urgently. In this paper, a large-size Fe3O4@SiO2 one-dimensional nanochains were synthesized and modified by means of different functionalization. On this basis, the application of one-dimensional nanochains in the flow injection chemiluminescence analysis was explored. Glucose oxidase was immobilized on the Fe3O4@SiO2 nanochains, which as a packed stationary phase, was successfully coupled with the flow injection system through the optimization of experimental conditions. As a result, a novel flow injection chemiluminescence analysis of glucose was developed. It has been proven that the one-dimensional nanochains-based packed stationary phase not only retains similar catalytic sites as the free magnetic particles, but also effectively overcomes the problem of poor fluidity of the free fixed phase. Therefore, it is expected to explore more high-performance flow injection analysis systems by strategies of the nanochain-immobilized enzyme-based packed stationary phase.","PeriodicalId":9794,"journal":{"name":"Catalysts","volume":"16 7","pages":"617-617"},"PeriodicalIF":0.0,"publicationDate":"2026-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148672239","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}

The use of microwave radiation in the process of material synthesis has a number of advantages, but also some disadvantages in comparison with the traditional hydrothermal synthesis method. The advantages and disadvantages of microwave synthesis of zeolites and zeolite-like materials are presented in the review. The use of microwave synthesis makes it possible to significantly reduce synthesis time, reduce energy costs, and obtain particles with a narrow distribution, usually in the nanoscale range (50–500 nm). The groups of zeolites considered include LTA, BEA, MOR, MFI, MEL, FAU, F, P, T, FER, ANA, MTT, ZSM–22, ZSM-48, SOD, SSZ-11, SSZ-13, SSZ-51, SSZ-54, and others. Among the zeolite-like materials synthesized using microwave radiation, mesoporous silicates MCM-41, SBA-15, alumophosphates, and metallaluminophosphates (AlPO-5, AlPO-11, AlPO-18, SAPO-5, SAPO-11, SAPO-34, SAPO-35) are considered. The proposed methods (microwave processing) significantly expand the range of methods for synthesizing new materials. These methods can reduce the synthesis temperature and affect the structure of the resulting materials. The proposed methods increase the likelihood of obtaining new nanomaterials and hybrid materials, as well as improving the properties of existing ones.","PeriodicalId":9794,"journal":{"name":"Catalysts","volume":"16 4","pages":"332-332"},"PeriodicalIF":0.0,"publicationDate":"2026-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.mdpi.com/2073-4344/16/4/332/pdf?version=1775379406","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147880114","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}

Herein, we synthesized a Cu-doped ZnIn2S4 (ZIS) catalyst with S-vacancy (Cun-VZIS) via hydrothermal synthesis, incorporating sulfur vacancies and directionally substituting copper ions for zinc ions. The experimental results elucidate the synergistically photocatalytic mechanism associated with the two types of defects. Both the sulfur vacancies within the structure and the copper doping sites lead to a reduction in the size of the ZnIn2S4 unit cell. The sulfur vacancy traps electrons, thereby mitigating the recombination of photogenerated carriers. Meanwhile, the copper ions optimize the carrier migration pathways, enhancing the overall carrier separation efficiency. Consequently, Cu1.5-VZIS demonstrates a stable and markedly enhanced photocatalytic hydrogen production activity, achieving a performance that is 7.5 times greater than that of pristine ZIS. Our study elucidates the effect of vacancy defects and ion doping on the photogenerated charge dynamics in ZIS, and paves a novel pathway for optimizing carrier dynamics through the concurrent utilization of both types of defects.","PeriodicalId":9794,"journal":{"name":"Catalysts","volume":"16 4","pages":"289-289"},"PeriodicalIF":0.0,"publicationDate":"2026-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.mdpi.com/2073-4344/16/4/289/pdf?version=1774433440","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147878761","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}

A continuous optimization of the hydrothermal and carbonization conditions was carried out for the preparation of α-MoC1−x. The biphasic molybdenum carbide catalysts were further achieved via vanadium doping with a phase transition of molybdenum carbide from α to β, which increased the specific surface area of the electrocatalyst.

To address these challenges, we introduced Cu as a promoter, resulting in the development of NiCu/ZSM-5 catalysts with significantly enhanced phenol selectivity and durability. Characterization studies revealed that Cu species form an alloy structure with Ni, which effectively suppresses the sintering of Ni nanoparticles during the catalytic process, thereby maintaining consistent performance over multiple reaction cycles. Furthermore, the Cu-Ni alloy demonstrated improved hydrogen activation capability while reducing overall H2 uptake, leading to a marked increase in phenol selectivity compared to the Cu-free Ni/ZSM-5 catalyst. As a result, the Ni1Cu1/ZSM-5 (Ni/Cu molar ratio = 1:1) catalyst achieved a lignin conversion of 69.8% and a phenol selectivity of 84.4%, with negligible performance degradation over 8 cycles.

(E) 2-(Furan-2-methylene)-3,5,5-trimethylcyclohex-1-one (1A) was obtained by selective hydrogenation of isophorone to obtain 3,3,5-trimethylcyclohexanone (TMCH), which was then subjected to aldol condensation with furfural.
