In this porphyrin, the Ir-motif acts as a triplet energy donor, while the porphyrin moiety serves as a singlet energy acceptor. An efficient Förster resonance energy transfer from the Ir-motif to the porphyrin moiety enables exceptional light-harvesting capabilities in the broad ultraviolet–visible region, a longer photoexcited state electron lifetime, and a higher photoluminescent quantum yield for T-Ir-ZnPF compared to ZnPF without the Ir-motif. Moreover, T-Ir-ZnPF exhibits inhibition of aggregation-caused quenching, resulting in suppressed nonradiative decay channels and consequently long-lived photoexcited states. The cocatalyst-free homogeneous photocatalytic hydrogen evolution (PHE) system of T-Ir-ZnPF produces a PHE rate (ηH2) of 5.34 mmol g⁻¹ h⁻¹. Under the same photocatalytic conditions, ZnPF did not produce hydrogen, while Ir-NH2 delivered a very low ηH2 of 0.20 mmol g⁻¹ h⁻¹. Since the Stern–Volmer quenching constant of T-Ir-ZnPF is higher than those of ZnPF and Ir-NH2, the photoexcited reduced T-Ir-ZnPF species are formed more readily by gaining electrons from triethylamine. Subsequently, a direct and fast electron transfer from the reduced T-Ir-ZnPF to protons leads to a high cocatalyst-free PHE.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 17","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/cctc.202500950","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144999094","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}

This work describes the first paradigm of a polyoxometalate (POM) compound, Na6V10O28·18H2O (1), that per se exhibits aqueous homogeneous electrocatalytic oxygen reduction reaction (ORR). Compound 1 is not only a well-known and versatile POM compound but has also been extensively studied as far as its biological activities are concerned. However, it was never known that it has the ability to perform electrocatalytic ORR. In literature, a limited number of studies exist regarding POM-based materials that have been immobilized within various nanomaterials and employed as heterogeneous electrocatalysts for the ORR. Compound 1 demonstrates remarkable electrochemical stability in solution, as confirmed by a prolonged (10-hour) constant potential electrolysis. Throughout this extended electrolysis, compound 1 maintains its integrity without undergoing decomposition or electrodeposition, which has been rigorously verified through various spectroscopic and microscopic analyses. The K-L plot derived from the RDE experiment reveals that the number of electrons transferred for this ORR is 2.7 (at a potential of −0.5 V vs. NHE). The use of rotating ring-disc electrode (RRDE) experiments and spectrophotometry techniques have confirmed the electrochemical generation of H2O2. Compound 1 is involved in a two-electron transfer reaction mixed with a four-electron transfer reaction, generating 53% H2O2 by two-electron oxygen reduction.","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 16","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144905446","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}

We address this critical limitation through an electrochemical-enzymatic hybrid system employing 1,1′-ethylene-2,2′-bipyridinium (DB∙+) as an artificial coenzyme for Candida boidinii formate dehydrogenase (CbFDH). This synthetic mediator demonstrates superior electrochemical regeneration at −0.65 V versus Ag/AgCl, maintaining unidirectional redox activity that exclusively drives CO2-to-formate conversion while eliminating parasitic reverse reactions. Our engineered three-compartment electrolyzer achieves spatial decoupling of DB∙+ regeneration from enzymatic catalysis, delivering six distinct current response cycles within 60 min and sustaining a formate production rate of 0.158 mM/min. System optimization at pH 6.3 yields a maximum formate concentration of 9.5 mM with 75.5% Faradaic efficiency. Mechanistic investigations reveal pH-dependent substrate specificity: HCO3− acts as a competitive inhibitor under alkaline conditions (pH 7.4), while CO2/H2CO3 serves as the exclusive enzymatic substrate at optimal pH 6.3. This work pioneers a paradigm for substituting biological cofactors with synthetic analogues, proposing a scalable architecture that harmonizes electrochemical potential regulation with enzymatic stereoselectivity for sustainable carbon utilization.

In particular, we provide a novel method to synthesize tungsten oxide catalysts by anodization of tungsten using an ionic liquid, [EMIN][BF4], as electrolyte in hydrodynamic conditions. We found that the use of appropriate hydrodynamic conditions (200–400 rpm) provides larger and more homogenous nanostructures with higher surface area. All this leads to better morphological and electrochemical properties. An excessive rotation during the synthesis (600 rpm) breaks the uniformity of the morphology of the nanostructures, thus hindering the photoelectrochemical performance. This way, the use of an optimized WO3 photoanode has shown excellent potential for photoelectrocatalytic water splitting. Moreover, these nanostructures also present good performance in the photoelectrocatalytic CO2 reduction, leading to the main formation of acetic acid, formic acid, and methanol. In fact, after only 6 h in continuous mode, a remarkable formic acid concentration of 190 µmol/L at 6 h has been obtained. Moreover, we have illustrated the great importance of the anode during the PEC reaction, significantly influencing the concentration of the obtained products owing to the electrons and protons transferred from the oxygen evolution reaction (OER).","PeriodicalId":141,"journal":{"name":"ChemCatChem","volume":"17 17","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://chemistry-europe.onlinelibrary.wiley.com/doi/epdf/10.1002/cctc.202500738","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144999095","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 partial reduction resulted in the formation of TiS2-x giving rise to Lewis acid centers. The Lewis centers interact with the polar protic solvent in the reaction medium, forming H+ moieties which facilitated the dehydration of fructose.

The activation energies (140–160 °C) for fructose dehydration and HMF etherification were 44.67 kJ/mol and 20.86 kJ/mol respectively, which were comparable to other Brønsted acid catalysts.

The findings demonstrate that reduced Ru-LaNiO3 catalyst achieved superior performance with 100% guaiacol conversion and a 75% selectivity toward cyclohexanol, compared to reduced Ru-NiTiO3, which achieved only 43% conversion and 25% cyclohexanol selectivity under identical conditions (240 °C, 30 bar H2, and 4 h). High-resolution transmission electron microscopic (HR-TEM) analysis reveals that LaNiO3-supported catalysts exhibit better metal dispersion and smaller nickel nanoparticle sizes compared to NiTiO3-supported counterparts. X-ray photoelectron spectroscopy (XPS) analysis shows that the reduction of nickel and noble metals is more facile on LaNiO3. Additionally, the O 1s XPS profile for reduced Ru-LaNiO3 indicates a higher proportion of lattice oxygen (OLat ∼ 79%) and a lower proportion of oxygen vacancies (OVac ∼ 21%) compared to other catalyst systems. The optimized OLat/OVac ratio is shown to be critical for the effective HDO of guaiacol. In situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) demonstrates a high HDO reaction rate using reduced Ru-LaNiO3 than reduced Ru-NiTiO3, with cyclohexanol formation attributed to the keto-enol tautomerization pathway.
