These near-isostructural analogs differ primarily in the coordination environment of the central metal: Sb has a coordination number (CN) of 4, while Bi exhibits a CN of 5. Notably, β-RbBiP₂S₆ is another form of a Rb/Bi/P/S compound with a 1126 stoichiometry. The β-phase, detailed in this work, is synthesized via direct combination, whereas the previously reported α-phase forms through a reactive Rb/Bi salt flux. The α- and β-phases also differ primarily by the Bi coordination sphere: α-phase Bi CN = 7; β-phase Bi CN = 5. RbSbP₂S₆ and β-RbBiP₂S₆ are both semiconductors. RbSbP₂S₆ has a bandgap of 2.68 eV while β-RbBiP₂S₆ has a bandgap of 2.06 eV. Neither material is congruently melting, but both have successfully been grown into large single crystals via slow cooling of the melt. Nonlinear optical (NLO) results in powder samples show that the symmetry breaking, which leads to lower dimensionality, also leads to significantly lower second harmonic generation (SHG) intensity (∼0.1x AgGaSe₂ for β-RbBiP₂S₆ vs ∼12x AgGaS₂ for α-RbBiP₂S₆). Third Harmonic Generation (THG) in powder samples show similar intensities (∼0.3x AgGaSe₂ for β-RbBiP₂S₆ and ∼0.1x AgGaSe₂ for RbSbP₂S₆). These are corroborated by single crystal SHG results for β-RbBiP₂S₆ (∼0.5x AgGaSe₂). The nonzero NLO coefficients <i>d</i>₁₄, <i>d</i>₂₅, and <i>d</i>₃₆ at 1550 nm fundamental wavelength are measured to be 9.5 ± 2.4, 17.2 ± 3.2, and 3.6 ± 2.3 pm/V, respectively. β-RbBiP₂S₆ has a comparable laser-induced damage threshold (LIDT) to AgGaSe₂ while RbSbP₂S₆ has a LIDT approximately 3x that of β-RbBiP₂S₆ attributed to its higher bandgap.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"27 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143666651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This material exists in various phases, such as NaSbS₂, NaSbS, Na₃SbS₄, and Na₂Sb₄S₇, and can be obtained only by annealing at high temperatures. However, here, we report the controlled formation of two different phases of sodium antimony sulfide, NaSbS₂, and a heterostructure of NaSbS₂/Na₂Sb₄S₇ achieved in a single successive ionic layer adsorption and reaction (SILAR) cycle without annealing procedures. Both phases were formed in two distinct colors, namely, orange (NaSbS₂) and brown (Na₂Sb₄S₇/NaSbS₂), and were found to be two different materials with different electronic properties. The band gaps for both phases were calculated to be 2.0 and 1.6 eV, which lies in the ideal band gap region for a solar absorber. Two photodetectors were fabricated, where both phases acted as the active layers with fluorine-doped tin oxide (FTO) and carbon as the other two electrodes. Both devices produced an outstanding photocurrent and photovoltage under zero-bias conditions, proving to work as excellent self-powered photodetectors. The devices were tested under 455, 525, 632 nm, and white light-emitting diode (LED) light illumination. The rise and fall times under light irradiation were as rapid as 380 and 480 ms for the NaSbS₂ device and 370 and 420 ms for the Na₂Sb₄S₇/NaSbS₂ device, respectively. The responsivity and detectivity for both the photodetectors at low intensities were found to be 0.89 and 3.5 mA/W and 8.8 × 10⁹ and 4.7 × 10¹⁰ Jones, respectively.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"183 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143666649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method of functionalization is developed as an alternative approach to thiolate functionalization of the gold surface. GNRs are synthesized using cetyltrimethylammonium bromide (CTAB), which is challenging to displace with thiols in high yield. In this work, a shell of SiO₂ is instead deposited on the outer surface of the GNRs, which also maintains colloidal stability. A reaction with a vinyl silane then prepares the outer surface of the SiO₂ shells for subsequent thiol–ene click reactions with five thiols that are selected to represent variations in structure and functional groups, including aliphatic and aromatic structures and acids and bases, demonstrating the versatility of the reaction. The SiO₂ shell is initially 17 nm thick and further grows to 20 nm when functionalized with vinyl groups. Deposition of vinyl groups and the formation of thioethers are confirmed by Fourier-transform infrared (FTIR) spectroscopy and time-of-flight secondary ion mass spectrometry (ToF-SIMS). While FTIR spectroscopy is well-known for characterizing the surface of nanoparticles, ToF-SIMS has been applied less for this purpose and strongly complements analysis by FTIR spectroscopy.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"56 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143672499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The synergistic effects of iodine substituting for selenium and copper occupying the intercalation position collectively increase the carrier concentration. Concurrently, microstructure analysis results reveal that multiscale defects such as dislocations, (Bi,Sb)SeI nanoprecipitates, elemental segregation, and subgrain boundaries are introduced into BiSbSe₃ via CuI compositing, which enhances the multifrequency phonon scattering. Ultimately, benefiting from the trade-off between the power factor and thermal conductivity, BiSbSe₃+0.02CuI parallel to the hot-pressing direction attains an excellent <i>ZT</i> value of ∼ 0.64 at 673 K, representing approximately a 12-fold improvement over that of pristine BiSbSe₃.

In situ characterization by XPS, EPR, and KFAM confirmed the formation of an S-scheme heterojunction between the composite catalysts. At the same time, electrochemical and fluorescence characterization confirmed that the photogenerated carrier separation efficiency of the CL-25 composite catalyst was significantly improved. This is because the built-in electric field at the interface of the composite catalyst exerts the polarizing electric field between the individual catalysts to an extreme degree, greatly reducing the recombination rate of photogenerated carriers and effectively improving the hydrogen evolution efficiency of the composite photocatalyst.

The electrochemical CO₂ reduction reaction (eCO₂RR) provides a sustainable approach by converting waste CO₂ into value-added products. However, achieving a high selectivity for multicarbon products in the eCO₂RR requires advanced catalysts with large surface areas, accessible active sites, and strong synergistic interactions. Here, we introduce a dual-atom Fe/Cu-NC catalyst synthesized through a metal–organic framework (MOF)-derived method where Fe and Cu atoms are uniformly dispersed on a porous nitrogen-doped carbon matrix, forming dual heteroactive Fe–N₄ and Cu–N₃ sites. The strategic combination of these active sites significantly enhances catalytic performance, achieving a 67.4% Faradaic efficiency (FE) for ethanol at −0.8 V <i>vs</i> RHE in CO₂-saturated 0.5 M KHCO₃. In situ spectroscopic analysis confirms the formation of major *CO and *CHO intermediates during CO₂ electrolysis on the Fe/Cu-NC electrode, which are crucial for C–C coupling and ethanol production. DFT studies reveal that Fe–N₄ and Cu–N₃ sites synergistically lower the *CO intermediate energy barriers. Fe–N₄ enriches the local CO concentration, which migrates to Cu–N₃, enhancing ethanol production. This highlights MOF-derived dual-atom catalysts as a promising strategy for efficient CO₂ conversion into ecofriendly products with zero emissions.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"26 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143661005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Starting from the parent phase Li₇PS₆, several cation and anion substitution strategies have been attempted to increase the conductivity of the Li ions. Nonetheless, a detailed understanding of the thermodynamics of native defects and doping of Li argyrodite and their effect on the ionic conductivity of Li is missing. Here, we report a comprehensive computational study of the defect chemistry of the parent phase Li₇PS₆ in both intrinsic and extrinsic regimes, using a newly developed workflow to automate the computations of several defect formation energies in a thermodynamically consistent framework. Our findings agree with known experimental findings, rule out several unfavorable aliovalent dopants, and narrow down the potential promising candidates that can be tested experimentally. We also find that cation–anion codoping can provide a powerful strategy to further optimize the composition of argyrodite. In particular, Si–F codoping is predicted to be thermodynamically favorable; this could lead to the synthesis of the first F-doped Li-containing argyrodite. Finally, using DeePMD neural networks, we have mapped the ionic conductivity landscape as a function of the concentration of the most promising cation and anion dopants identified from the defect calculations, and identified the most promising region in the compositional space with high Li conductivity that can be explored experimentally.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"1 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143654037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, silicon-based inorganic compounds containing silicon and oxygen have attracted significant attention. Of these, one intriguing nanostructure is Siloxene, a 2D oxide of silicon. Its close structural resemblance to 2D carbon compounds provides an opportunity to explore chemistries similar to carbon in silicon. Here, we have investigated the stability and reduction of Si═O bonds in 2D-Siloxene using hydrazine in potassium hydroxide. The reduction of 2D Siloxene shows striking similarity to Wolff–Kishner reduction, which is well-known in carbon chemistry. Specifically, the polarization of the Si═O bond in Siloxene results in charge separation between the silicon and oxygen atoms. This significantly enhances the reactivity of the Si═O bond and renders it susceptible to reduction. Mulliken charge analysis within the framework of density functional theory calculations suggests the electronegative behavior of O atoms, when attached to Si both as Si═O and Si–OH. The electropositive Si atom in Si═O is attacked by hydrazine hydrate, subsequently, when treated with a strong base, typically potassium hydroxide, affects the reduction of the hydrazone. Our study provides strong theoretical and experimental evidence for a reduction mechanism analogous to the Wolff–Kishner reduction, in 2D silicon, enabling developing insights in silicon reduction.","PeriodicalId":33,"journal":{"name":"Chemistry of Materials","volume":"6 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
