In this study, a metal-containing hydrogen-bonded organic framework (HOF) of manganese coordinated with 2,2'-bipyridine-6,6'-dicarboxylate ligands, Mn(bda), interconnected through hydrogen bonding and π-π stacking is used as a heterogeneous OER catalyst (Mn(bda)-HOF) for acidic water oxidation and exhibits a considerable OER performance. Electrochemical results show that Mn(bda)-HOF displays a turn of frequency of 1 s<sup>−1</sup> at an overpotential of 870 mV. Meanwhile, this Mn(bda)-HOF shows an unusual pH dependence on performance, where the reaction rate increases with the decrease of pH. A comprehensive mechanistic study reveals that the charge transfer triggered coupling of two metal-oxo species Mn<sup>5+</sup>(O) is the rate-determining step, which leads to this unusual pH dependence on the OER performance.</div></div>","PeriodicalId":10151,"journal":{"name":"结构化学","volume":"44 3","pages":"Article 100535"},"PeriodicalIF":5.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143629971","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}

Consequently, the Ni<sub>3</sub>S<sub>2</sub>-WO<sub>3</sub>/NF presents a remarkably low potential of 1.38 V to reach 10 mA cm<sup>−2</sup> for UOR-assisted HER.
