However, water electrolysis, which is the primary technique for achieving large-scale and low-carbon hydrogen production, still suffers from high production costs and energy consumption. The key is to develop highly efficient electrochemical water splitting catalysts. In recent years, the preparation of electrocatalysts via plasma treatment has gained recognition for its rapid, eco-friendly, and controllable properties, especially in the optimization of nano-microstructure. This review comprehensively summarizes the impact of plasma treatment on the nano-microstructure of water electrolysis catalysts, encompassing dispersion enhancement, morphology modulation, surface functionalization, defect construction, and element doping. These impacts on the nano-microstructure increase the surface area, modify the pore structure, introduce active sites, and regulate the electronic environment, thereby promoting the water splitting performance of electrocatalysts. Finally, the remaining challenges and potential opportunities are discussed for the future development of plasma treatment. This review would be a valuable reference for plasma-assisted electrocatalyst synthesis and mechanism understanding in plasma impact on nano-microstructure.</div></div>","PeriodicalId":10151,"journal":{"name":"结构化学","volume":"44 3","pages":"Article 100520"},"PeriodicalIF":5.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143627943","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}

Here, we design and synthesize a new Zn-based metal azolate framework (MAF), MAF-40, with a three-dimensional (3D) honeycomb-like framework and 1D sugar-coated-berry type pore channels. By virtue of the strong coordination bonds and abundant trifluoromethyl groups embedded in the pores, MAF-40 exhibits excellent thermal stability (up to 400 °C) and acid-base stability (within a pH range of 3–11). Moreover, MAF-40 shows ultrahigh benzene selectivity (38.8) from the ternary benzene/cyclohexene/cyclohexane mixtures, attributed to the strong adsorption affinity from fluorine for benzene and markedly different guest diffusion limited by the small aperture, which are confirmed by computational simulations and infrared spectra. Thus, the results indicated that MAF-40 would be a candidate adsorbent for the separation and purification of benzene from C<sub>6</sub> cyclic hydrocarbons, and this work provides a new insight of synthesizing stable MOF materials for separating multicomponent chemical mixtures.</div></div>","PeriodicalId":10151,"journal":{"name":"结构化学","volume":"44 3","pages":"Article 100540"},"PeriodicalIF":5.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143629972","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}

The iron-doped MoS<sub>2</sub> catalysts have demonstrated potential in activating peroxymonosulfate (PMS) for environmental remediation, but they face challenges such as poor conductivity, limited electron transfer efficiency, and a scarcity of active sites. To address these issues, we successfully synthesized a nano-flowers FeS/MoS<sub>2</sub> composite derived from polyoxometalates (NH<sub>4</sub>)<sub>3</sub>[Fe(III)Mo<sub>6</sub>O<sub>24</sub>H<sub>6</sub>]·6H<sub>2</sub>O (denoted as FeMo<sub>6</sub>) as the bimetallic precursors. This synthesis strategy enhances the interaction between FeS and MoS<sub>2</sub>, thereby facilitating electron transfer. Notably, the introduction of sulfur vacancies in FeS/MoS<sub>2</sub> exposes additional Mo<sup>4+</sup> active sites, promoting the redox cycle of Fe<sup>2+</sup>/Fe<sup>3+</sup> and accelerating the regeneration of Fe<sup>2+</sup>, which in turn enhances PMS activation. Therefore, a catalytic oxidation system of FeS/MoS<sub>2</sub>/PMS is presented that primarily relies on SO<sub>4</sub><sup>·</sup><sup>−</sup> and ·OH, with <sup>1</sup>O<sub>2</sub> as a supplementary oxidant. This system exhibits exceptional degradation efficiency for p-chlorophenol (4-CP), achieving 100% degradation within 10 min over a wide pH range of 2.4–8.4. The robust performance and wide applicability of FeS/MoS<sub>2</sub> catalyst make it a promising candidate in advanced oxidation processes (AOPs) for environmental remediation.</div></div>","PeriodicalId":10151,"journal":{"name":"结构化学","volume":"44 3","pages":"Article 100543"},"PeriodicalIF":5.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143629973","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}
