Upon deprotonation, NO2-TRIADs form stable diamantane-like complexes with manganese, iron and nickel in atypical +4 oxidation state. These complexes were characterized by XRD analysis, NMR, Mössbauer spectroscopy, UV-Vis, FT-IR, HRMS, and elemental analysis. Theoretical analysis based on DFT calculations revealed a remarkable electron donating “α-effect” of the nitrogen atom in the N–O–M fragment that is responsible for the stabilization of the higher oxidation state of the metal in these complexes. Metal(IV) complexes of NO2-TRIADs exhibit high catalytic activity in oxidation reactions, in particular, in the aerobic conversion of thiols into disulfides (up to 98% yield) and oxidation of activated C–H bonds in diphenylmethanol and dihydroanthracene with mCPBA (up to 74% yield).

The hydrogen evolution rate of Zn-K-CN is 31.2 μmol, which is significantly higher than that of pure g-C3N4. Its apparent quantum efficiency (AQE) was up to 2.9 % at 420 nm. Significantly, the photocatalytic performance can remain stable for 12 h for four consecutive cycles. This remarkable performance can be attributed to the enlarged surface area, which provides a greater number of reactive sites, the narrow bandgap that enhances the absorption of visible light, and the negatively positioned conduction band edge, which facilitates hydrogen reduction.","PeriodicalId":71,"journal":{"name":"Dalton Transactions","volume":"32 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144097003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The underpotential deposited hydrogen (Hupd) tests and density-functional-theory (DFT) calculations further validate that the enhanced performance of Ru/C-220 stems from oxygen modification, which reduces and optimizes the *H adsorption energy at the Ru active sites.

Clayton, John S O Evans, Chris Greenwell, Russell Alan Taylor","doi":"10.1039/d5dt00694e","DOIUrl":"https://doi.org/10.1039/d5dt00694e","url":null,"abstract":"Magnesium-substituted microporous aluminophosphates (MgAlPOs) are tuneable framework materials that exhibit strong Brønsted acidity and have found great utility as catalysts for a wide variety of green transformations. Typically, refined magnesium salts, such as magnesium acetate, are the source of magnesium used in the synthesis of MgAlPOs. However, magnesium is classified as a critical raw material, thus finding alternative sources of magnesium remains an important endeavour. Here we demonstrate the use of struvite, a mineral which can form as a problematic waste material, as a viable source of magnesium for the synthesis of MgAlPO-5 (AFI framework). Exploration of synthesis conditions showed that using struvite over magnesium acetate as the Mg source led to increased chabazite (CHA) contamination when triethylamine was employed as the template. The CHA phase impurity could be reduced through synthesis optimisation, though not eliminated when struvite was utilised. Phase pure AFI from struvite and magnesium acetate was formed when N,N-methyldicyclohexylamine was used as a template, and the gel stirred during crystallisation. Electron microscopy revealed that the struvite derived MgAlPO-5 materials exhibit a distinct surface morphology featuring nanorod-like growths, presumably associated with the magnesium source, although the underlying cause remains unclear. Despite this we show that both materials are acidic (DRIFTS and CD3CN adsorption studies) and are active catalysts for the dehydration of ethanol to ethylene in the gas phase under flow conditions. In contrast, unsubstituted AlPO-5 shows limited acidity and negligible catalytic activity, validating the incorporation of magnesium into the framework from both magnesium sources. TEM-EDS maps also support this finding, showing a homogenous distribtution of Al, P and O (and Mg) for all materials synthesised. This work demonstrates that struvite can be used in MgAlPO synthesis, under optimised conditions, showing that repurposing this unconventional magnesium source is far from “a waste of time\".","PeriodicalId":71,"journal":{"name":"Dalton Transactions","volume":"61 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144088189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a novel type II heterojunction MOF-based composite BiOBr-Vo/MIL-101(Fe)-F was successfully constructed. The introduction of oxygen vacancies on BiOBr via a thermal calcination strategy, and in situ doping with F-modified MIL-101(Fe) using solvothermal method, facilitated the adsorption and activation of nitrogen in the photocatalytic nitrogen fixation. The fluorine modification in MIL-101(Fe) can effectively promote the separation of charge carriers, thereby further enhancing the photocatalytic efficiency. Photocatalytic experiments reveal that the BiOBr-Vo/MIL-101(Fe)-F (10 wt% doping) composite achieves an optimal nitrogen fixation rate of 80.9 μmolNH3⋅gcat-1⋅h-1 under visible light (≥420 nm), which is 2.8 times higher than that of the hybridised materials without F modification and 21 times higher than that of pristine BiOBr. The type II heterojunction also effectively suppresses the recombination of photogenerated electron-hole (e--h+) pairs, resulting in an efficient separation of the charge carriers and an enhanced photocatalytic activity for the reduction of nitrogen. Continuous stable catalytic activity over 8 cycles (lifetime ≥ 32 h) show a negligible activity loss, which is attributed to the robust coordination structure of the BiOBr-Vo/MIL-101(Fe)-F. This finding carries significant implications for the development of novel nitrogen reduction photocatalysts that exhibit both high efficiency and stability.","PeriodicalId":71,"journal":{"name":"Dalton Transactions","volume":"78 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144088188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
