However, inadequate ion diffusion, poor electron transfer, and significant volume fluctuations during prolonged charge and discharge cycles lead to severe structural deterioration and capacity loss, hindering their further practical application. Heterostructure engineering can not only alleviate the internal stresses and dramatic volume alterations induced by ion deintercalation, but also enhance the dynamics of ion transport. Adopting a dual-optimization strategy that incorporates heterogeneous structure construction and doping, we successfully synthesized ultra-thin Co doped SnS2/SnO2 heterostructure nanosheets on carbon cloth substrates via a co-nucleation growth process. After rigorous investigation into its lithium-ion storage performance and mechanisms, it exhibited excellent lithium storage capabilities (1518 mA h g−1 at 330 mA g−1, with 81% of the initial capacity retained after 100 cycles). Pleasingly, when incorporated into next-generation sodium-ion batteries, Co-doped SnS2/SnO2 anodes exhibit highly competitive sodium storage capabilities (1250 mA h g−1 at 220 mA g−1, with 97.8% of the initial capacity retained after 200 cycles). The incorporation of Co ions and the formation of heterostructures have been confirmed to enhance ion diffusion and reaction kinetics. This study presents a novel approach for the facile preparation of multifunctional Li and Na ion storage materials featuring element-doped heterogeneous compositions.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142448159","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}

Although hydrometallurgy is highly recognized for realizing the high-value recycling of critical metal elements from leaching solutions via chemical purification methods, its associated complex operations, large chemical consumption, and low efficiency fail to meet sustainability and eco-friendliness considerations, requiring an innovative separation approach to achieve these aims. Electrodialysis (ED) has emerged as an advanced membrane separation technology offering continuous operation and scalability advantages but has yet to be widely applied in recycling critical metals from the leaching solutions of spent LIBs. In this review, we introduce the fundamentals and evaluation indicators of the ED technique. Besides, the challenges of ED in metal extraction from the leaching solution are discussed. In addition, strategies for improving the separation performance of ED are provided and highlighted.

Radical degradation pathways are highly regarded due to their wide application and efficiency in handling pollutants. Comparatively, direct oxidation by holes exhibits unique advantages in dealing with specific types of pollutants, and both degradation pathways have their own characteristics and strengths. However, past research on pollutant degradation has mainly focused on radical degradation, with little recognition of the role of direct hole oxidation in pollutant degradation, and there has been a lack of attention to the transition between the two pathways. This has made it difficult to select the most effective degradation strategy for different types of pollutants. To fill the cognitive gap in photocatalytic degradation pathways and break the predicament of blindly dealing with pollutants, the characteristics of these two oxidation pathways and their transition mechanisms are systematically explored. Additionally, this study provides the first summary of which types of pollutants are suitable for degradation by holes and radicals, respectively. This paper offers a clear basis for selecting the most appropriate photocatalytic strategy according to the characteristics of different pollutants and reaction conditions, aiming to enhance researchers' understanding of pollutant degradation and promote the development of environmental management technology towards higher efficiency and precision.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142443929","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}

Copper azide (CA), a primary explosive with excellent detonation properties, is limited in preparation and application owing to its extremely high sensitivity. Thus, incorporating CA into LSPEs relies on precise desensitisation strategies. This study successfully implemented a strategy involving sensitive-unit molecular-scale encapsulation. A 2D energetic metal–organic framework (EMOF) [Cu(ATRZ)(N3)2]n (CA-ATRZ) (ATRZ = 4,4′-azo-1,2,4-triazole) was designed and synthesized via a safe and facile single-crystal-to-single-crystal (SCSC) transformation from a 3D EMOF [Cu(ATRZ)3(NO3)2]n. Leveraging its distinctive structural attributes of encapsulated confinement, CA-ATRZ is substantially improved in terms of safety compared to CA, while maintaining its superior detonation performance. Furthermore, CA-ATRZ obtained by combining MOFs with CA has outstanding ultrafast direct laser initiation characteristics, is free of toxic metals and perchlorate, has high initiating ability, and has decent thermal stability. This strategy could pave the way for developing advanced high-energy LSPEs.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":null,"pages":null},"PeriodicalIF":7.0,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142444028","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 first compound [K(DME)2][U(dbCOT)2] (where DME = dimethoxyethane), 1, features a potassium ion interacting with one of the dbCOT ligands and was obtained from a salt metathesis reaction employing UI3(dioxane)1.5 and K2dbCOT. The second compound [K(crypt-222)][U(dbCOT)2], 2, arose from treating 1 with 2.2.2-cryptand, yielding an outer-sphere potassium ion. The third compound [K(crypt-222)][U(dbCOT)2(THF)], 3, was generated through the exposure of 1 to THF solvent and 2.2.2-cryptand, resulting in the coordination of THF to uranium(III) along with η8-ligation of each dbCOT ligand while placing the potassium ion outer sphere, encased in the chelating agent. Notably, the compounds present the largest uranocene derivatives, considering the presence of fused aromatic rings to the central COT framework, which bear a total of 36 π-electrons.

Herein, core-shell CaSnO3@N-doped carbon (CSO@NCNFs) coaxial nanocables with a one-dimensional (1D) architecture have been synthesized by the electrospinning method combined with in-situ polymerization and heat treatment. In the resulting placement, the CaSnO3 nanofibers (CSONFs) core with an average diameter of 52.5 nm is confined in the high electronic conductivity of the N-doped carbon sheaths with a thickness ranging from 27.3 to 67.2 nm. The lithium storage performance of the CSO@NCNFs nanocable electrode is much higher than that of the CSONFs electrode, due to (i) a large number of void spaces and active sites generated by the structure of the 1D core-shell nanocables, (ii) a fast transport network constructed by carbon sheaths prominently enhances the transport of both electrons and lithium ions, and (iii) the structural stability achieved through the buffering mechanism created by the CaSnO3@NCNFs coaxial construction. On the other hand, the ingenious structural design, multiple heterogeneous interfaces and multi-component strategy give rise to a synergistic mechanism of the impedance match condition, conductive dissipation, polarization dissipation and multiple reflection/scattering. The coaxial nanocables display good microwave absorption (MA) properties, featuring a reflection loss (RL) value of –47.0 dB at 8.2 GHz and 2.5 mm, and an effective absorption bandwidth (EAB) of 4.7 GHz at 1.4 mm.
