Experimental results indicate that the photoreduction treatment will generate a large number of Mo4+ ions inside the composite, and the appearance of Mo4+ greatly increases the concentration of free electrons in the composite. Moreover, DFT calculations show that abundant Mo4+ ions can enhance the metallic properties of the material, leading to the generation of oxygen vacancies. This effectively modulates the ability of the composite to capture electrons and the resistance of photogenerated carrier interface migration. The S-scheme heterojunction between CdS and H0.95MoO3 achieved effective spatial separation of photogenerated charges. Also, the LSPR effect extends the light response range to the near-infrared region of 1400 nm, which significantly improves light utilization, while the photothermal effect further increases the surface temperature of the composites. The above reasons promote the photocatalytic reaction to proceed rapidly. Notably, the optimized L-CMx has superior H2 evolution ability, reaching 20.9 mmol g−1 h−1 under visible light, and the AQY was 14.8% at 450 nm.

However, uncontrollable side reactions and dendrite growth remain significant challenges in developing aqueous zinc-ion batteries (ZIBs).

Herein, porous layered basic zinc acetate nanosheets (LBZA) were innovatively constructed to protect zinc anodes (LBZA@Zn) against uncontrollable side reactions and dendrite growth in aqueous ZIBs. The hydrophobic and positively charged surface eventually constructs a local high-concentration region, thereby facilitating the dissociation and transport of Zn2+, as well as reducing the hydrogen evolution reaction and the by-product growth of the Zn anode. The LBZA@Zn∥LBZA@Zn symmetrical cell has a cycling stability of 1800 h at 2 mA cm−2 and 1 mA h cm−2. While the LBZA@Zn∥Cu cell maintains stable deposition of Zn2+ after 5000 cycles at 1 mA cm−2 and 0.5 mA h cm−2, with a high average coulombic efficiency of 99.91%.

In the context of Cr(II) complexes with octahedral geometry, the pronounced Jahn-Teller distortion in the high-spin (HS) state significantly restricts the selection of co-ligands necessary for SCO to occur. In this study, we successfully synthesized a series of air-stable and solvent-free Cr(II) complexes, [Cr(TpmR)2]X2 (TpmR = Tpm: X = [BF4]-, 1; X = [ClO4]-, 2; TpmR = Tpm*: X = [BF4]-, 3; X = [ClO4]-, 4), where the Cr(II) ions adopt a trigonal antiprism (aTPR) geometry rather than the conventional octahedral configuration. Notably, the Tpm-based complexes 1 and 2, with Cr(II) ions in a nearly ideal aTPR geometry, exhibit complete SCO behavior with transition temperatures (T1/2) of 190 K for 1 and 194 K for 2, respectively. In contrast, the Tpm*-based complexes 3 and 4 display considerable axial elongation within the aTPR structure, leading to abrupt but incomplete SCO transition at a much lower temperature for 3 (T1/2 = 142 K) while 4 remains predominantly in the HS state. Further structural analysis reveals that substituting [BF4]- with [ClO4]- in 4 results in increased elongation and a denser packing arrangement that disfavour the spin transition. Our findings suggest that the aTPR configuration is advantageous for facilitating spin crossover, while the dynamics of spin transitions in these complexes are closely linked to the structural distortions of the [Cr(TpmR)2]2+ cations. Furthermore, all complexes demonstrate remarkable resistance to oxygen and maintain air stability, which can be attributed to their compact space-filling structures that effectively impede the diffusion of oxygen into the interstitial regions of the crystal lattice.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"1 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142981217","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}

Upon heating from 298 to 428 K, an anomalous enhancement in the intensity of the 415 nm emission in R-CCCH:Sn2+ was observed while its 540 nm emission underwent significant thermal quenching. The observation of the temperature-dependent photoluminescence (PL) indicates that R-CCCH:Sn2+ exists in a metastable state. Upon calcinating at 428 K for 20 min, the R-CCCH:Sn2+ changed to the stable state P-CCCH:Sn2+, exhibiting the STEs of CCCH matrix and the 3P1→1S0 transition of Sn2+.

Specifically, we have successfully synthesized a non-centrosymmetric Cd-containing sulfamic compound, KCd(NH2SO3)3, inspired by the perovskite architecture. The strategic incorporation of SO3NH2− groups at the X-sites not only induces distorted [CdO3N3] octahedra, thereby enhancing the SHG response, but also ensures an ultrawide bandgap, which enables excellent DUV transparency. Consequently, this material exhibits a strong SHG response, approximately 1.1 times that of KH2PO4 (KDP), with a DUV cutoff edge below 190 nm. Furthermore, large transparent single crystals (20 × 17 × 5 mm3) can be readily grown via a simple aqueous solution method, underscoring its potential for practical application. This innovative approach offers new design strategies for DUV NLO materials, overcoming the traditional trade-off between SHG response and UV transparency.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":" 4","pages":" 1656-1661"},"PeriodicalIF":6.1,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142975286","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}

In this study, Cu nanoparticles (Cu NPs) were utilized as a co-catalyst for forming Schottky junctions and induced plasma excitation. A simple molten-salt method was employed to prepare dispersed Cu NPs and stable OV, achieving dual regulation of photogenerated carrier separation kinetics and catalytic sites. The synergistic effect of LSPR and Schottky junction enhanced the thermodynamics and kinetics of photocatalytic reactions, facilitating the generation of photo-generated carriers, driving the directional migration of these carriers. The dual-channel regulation mechanism significantly enhanced the photocatalytic efficiency of the catalysts. The study revealed a significant enhancement in the photocatalytic efficiency of Cu10@TiO2, with a TC removal rate of 99.4% achieved within 25 min. The reaction rate was also found to be 3.12 times higher than that of pure TiO2, and enhanced performance remained stable even after multiple cycles. At the same time, the photocatalytic performances of catalysts were investigated in different water environments under various light sources. The results revealed that the as-prepared material maintained favorable photocatalytic activities in tap water, seawater, lake water, and pharmaceutical wastewater, which offers a promising opportunity to address real-life sewage management issues.
