Nonetheless, most of these crystals contain solvents or counter ions, and their effects during measurement or calculations are far from trivial. Therefore, synthesizing a solvent-free and neutral complex exhibiting polarization switching is highly desirable. Herein, we successfully observe directional charge transfer-induced electronic pyroelectricity in a solvent-free neutral cobalt complex, namely Co(teeda)(3,6-dbq)2 (teeda = N,N,N’,N’-tetraethylethane-1,2-diamine and 3,6-dbq = 3,6-di-tert-butylcatecholate or 3,6-di-tert-butylsemiquinonate). The charge transfer property is confirmed by magnetometry, infrared and UV-vis-NIR spectroscopy, and single-crystal X-ray diffraction (SCXRD) measurements. Furthermore, pyroelectric current is observed during the valence tautomerism (VT) process. Theoretical calculations demonstrate that the origin of polarization switching is mainly ascribed to the charge transfer. These results indicate that Co(teeda)(3,6-dbq)2 is a promising candidate for exploring new VT compounds that exhibit polarization switching.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142384477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microorganisms such as Escherichia coli (E. coli) are commonly used to produce hydrogen due to their high efficiency, wide choice of substrates, and fast growth rate. However, the hydrogenase in E. coli can only be activated to produce hydrogen under anaerobic conditions, which greatly limits its practical application as a hydrogen producing microorganism. Herein, we report a strategy to construct E. coli@ZIF-8 micro–nano reactors (MNRs), in which the metal–organic framework (MOF) shell serves as armour to provide E. coli with a hypoxic environment that activates hydrogenase and achieves hydrogen production even in air. The MOF shell of the E. coli@ZIF-8 MNR regulates the hydrogen production time by modulating oxygen transport, and thicker MOF shells can effectively delay oxygen diffusion, resulting in faster hydrogen production. Meanwhile, the survival rate of E. coli is improved with the increase of the MOF shell thickness, which is three times higher than that of pure E. coli when cultured in deionized water. This biohybrid system regulates microbial metabolism, which is promising for expanding the applications of microbial hydrogen production.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":6.1,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142384476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we synthesize a hierarchical core-shell CuS@CuSe catalyst, exhibiting a controllable selectivity from 67.5% for HCOOH at −0.5 V vs. RHE to 54.7% for C2H5OH at −0.9 V vs. RHE. The overlap-labeled transmission electron microscopy and in-situ Raman spectroscopy dynamically monitor the potential-dependent structural evolution from the pristine CuS@CuSe to CuS@Cu2Se with Se vacancies (Cu2Se-VSe). Density functional theory (DFT) calculations reveal that the generated Se-vacancies stabilize Cu+ sites with shortened Cu−Cu spacing of 2.46 Å, which not only increases affinities to the adsorbed *COOH and *CO species but also promotes the easier dimerization of *CO to form *OCCO (ΔG ∼ −0.50 eV) while suppressing its direct desorption to CO (ΔG ∼ +1.63 eV) or hydrogenation to *CHO (ΔG ∼ +0.74 eV) and *COH (ΔG ∼ +1.15 eV), which is believed to determine the remarkable ethanol selectivity. And, the rapid dissociation of water over the synergistic CuS sites kinetically accelerates the proton-coupling process. Such potential-dependent imperative intermediates associated with the bifurcated pathway are directly distinguished by isotope labelling in-situ infrared spectroscopy. This work confers the prospect of designing electrochemical reconstructed copper chalcogenides catalyst for tuning C1/C2 products selectivity in CO2RR technology.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142384503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ammonia generation rate over the Cu/WO2/C-BOB heterojunction is 477.5 μmol g-1 h-1 in deionized water without any sacrificial reagents under full solar spectrum, which is nearly 6.1 times greater than pure BiOBr. The synergistic effect of heteroatom doping, Z-scheme heterojunction and oxygen vacancies inhibits the recombination of photogenerated carriers and maintains their maximum redox capacity, providing more reaction sites and significantly improving the photocatalytic performance. In addition, the localized surface plasmon resonance effect (LSPR) of Cu NPs enhances light absorption and motivates high-energy hot electrons to produce additional oxygen vacancies. Meanwhile, we explored the charge transfer pathways and possible reaction mechanisms of the heterojunctions through experimental characterization and DFT calculations, which provided a new idea to synergistically utilize the LSPR effect and Z-scheme heterostructures for the design of efficient photocatalysts.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142384475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we report the first example of Δ/Λ configurational inversion of metal centers independent of the P/M conformational conversion. The helicate (NMe4)2[Eu2(LR)4], maintaining a constant P helical conformation, undergoes a local metal center configurational conversion from ΛΛ-(NMe4)2[Eu2(LR)4] → ΔΛ-(NMe4)2[Eu2(LR)4] → ΔΔ-(NMe4)2[Eu2(LR)4] upon increasing the content of CHCl3 in CH3CN. Associated with the conversion, the inversion of circularly polarized luminescence (CPL) activity took place with the luminescence dissymmetry factor (glum value) changing from −0.23 to +0.44. The understanding thus gained as to the solvent's impact on local chirality inversion enabled the design of CPL optical switches or sensors based on lanthanide helicates.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":6.1,"publicationDate":"2024-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142377280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pristine Cs2NaScCl6 crystals exhibited a pure blue emission band originating from the self-trapped excitons. Upon doping with Mn2+, the crystals exhibited a dual-band emission profile, consisting of both STE and Mn2+ emissions. To this end, the ratio of two bands was manipulated with Mn2+-doping concentration, rendering a wide color gamut from blue to red. Interestingly, co-doping with Sb3+ ions significantly enhanced the overall photoluminescence, boosting the quantum yield from 8.8% to up to 62.4%. Such an enhancement is attributed to an efficient energy transfer process from the STE to Mn2+ based on an investigation of photoluminescence lifetime.
