Abstract ：
Herein, cobalt ammine complexes are combined with alkali-resistant polyoxoniobates (PONbs) at the molecular level to obtain two new organic-inorganic hybrid Co-containing PONbs with the same polyanions but different Co contents. The Co-containing PONb with higher Co content exhibits superior hydrogen evolution reaction (HER) activity under highly alkaline conditions, which is better than the results for the similar Cu-containing PONb, highlighting the critical role of cobalt in improving HER performance. This study provides a new insight into the relationship between the structural properties of metal complexes during electrocatalysis.

Abstract ：
Electrochemical carbon dioxide reduction to multi-carbon (C2+) products presents a significant opportunity for converting greenhouse gases into valuable fuels and feedstocks. The development of highly active and stable catalysts remains a critical challenge. In this study, we report the design and synthesis of cyclodextrin-modified Cu/Cu2O electrocatalysts, which exhibit remarkable efficiency in driving the CO2 electroreduction process towards C2+ products. Our optimized catalyst achieves a C2+ Faradaic efficiency exceeding 50 % at a high current density of over 200 mA cm(-2). Experimental findings, supported by density functional theory (DFT) calculations, reveal that cyclodextrin plays a dual role in stabilizing Cu+ and increasing the surface density of hydroxyl radicals. This dual function greatly benefits for enhancing *CO intermediate adsorption and promotes *CHO formation, thereby facilitating the crucial dimerization step for the formation of C2+ products. This work provides valuable insights into the development of highly active and selective electrocatalysts by carefully tuning the local catalytic environment, potentially opening new avenues for functionalizing electrocatalysts for future research in this area.

Abstract ：
A series of novel cage-like transition-metal (TM) incorporated heteropolyoxoniobates {TM4Nb64O200} (1-TM, TM = Ni, Cu, Mn, Cd) were hydrothermally synthesized and isolated as salts of mixed K+ and [CN3H6]+. As a result of transition metal ions incorporation, the charge distribution, redox potential, and active sites of the formed polyoxoniobates (PONbs) are variants, leading to differences in their electrocatalytic hydrogen evolution reaction (HER). Among these compounds, 1-Ni showed the best HER activity with an overpotential of 560 mV at 10 mA cm-2 and a minimum Tafel slope of 405.8 mV dec-1.

Abstract ：
Atomically precise low-nuclearity (n<10) silver nanoclusters (AgNCs) have garnered significant interest due to their size-dependent optical properties and diverse applications. However, their synthesis has remained challenging, primarily due to their inherent instability. The present study introduces a new feasible approach for clustering silver ions utilizing highly negative and redox-inert polyoxoniobates (PONbs) as all-inorganic ligands. This strategy not only enables the creation of novel Ag-PONb composite nanoclusters but also facilitates the synthesis of stable low-nuclearity AgNCs. Using this method, we have successfully synthesized a small octanuclear rhombic [Ag-8](6+) AgNC stabilized by six highly negative [LiNb27O75](14-) polyoxoanions. This marks the first PONb-protected superatomic AgNC, designated as {Ag-8@(LiNb27O75)(6)} (Ag-8@Nb-162), with an aesthetically spherical core-shell structure. The crystalline Ag-8@Nb-162 is stable under ambient conditions, What's more, it is water-soluble and able to maintain its molecular cluster structure intact in water. Further, the stable small [Ag-8](6+) AgNC has interesting temperature- and pH-dependent reversible fluorescence response, based on which a multiple optical encryption mode for anti-counterfeit technology was demonstrated. This work offers a promising avenue for the synthesis of fascinating and stable PONb-protected AgNCs and sheds light on the development of new-type optical functional materials.

Abstract ：
Nature seems to favor the formation of closed anion-templated silver clusters. How precisely to create non-closed sliver clusters remains an interesting challenge. In this work, we propose that the use of transition-metal-coordination-cluster substituted polyoxometalates (TMCC-substituted POMs) as templates is an effective synthetic strategy for creating the non-closed silver clusters, as demonstrated by the obtainment of four types of rare non-closed silver cluster species of Ag38-TM (TM = Co, Ni or Zn), Ag37-Zn, {Ag37-Zn}infinity and Ag36-TM (TM = Co, Ni). The idea of the strategy is to employ the TMCC-substituted POMs containing cluster modules with different bond interactions with Ag+ ions as templates to guide the formation of the non-closed silver clusters. For example, TMCC-substituted POM clusters are used as templates in this work, which contain POM modules that can coordinate with the Ag+ ions and TMCC moieties that are difficult to coordinate with the Ag+ ions, leading to the Ag+ ions being unable to form closed clusters around TMCC-substituted POM templates. The work demonstrates a promising approach to developing intriguing and unexplored non-closed silver clusters. Using transition-metal-coordination-cluster-substituted polyoxometalates as templates, four kinds of rare non-closed silver cluster species are obtained, demonstrating a promising strategy for the development of uncommon non-closed silver clusters.

Abstract ：
Selective uptake and elution of trace amounts of hazardous radioactive Sr-90 from large-scale high-level liquid waste (HLW) is crucial for sustainable development. Here, we propose a site differentiation strategy, based on the presence of distinct selective metal capture sites (concavity site and tweezer site) within the giant polyoxoniobate (PONb) nanoclusters of an all-inorganic PONb framework (FZU-1). Through this strategy, FZU-1 can not only effectively remove 98.9% of Sr2+ from simulated nuclear liquid waste, performing best among the reported Sr adsorbents, but also achieve desorption of adsorbed Sr2+ ions by selectively loading Na+ ions, thus enabling the recycling of FZU-1. Based on the well-defined single-crystal structures and theoretical studies, it can be revealed that the rapid and selective uptake of Sr2+ is attributed to the strong binding energy between the Sr2+ ions and the concavity sites. The effective elution of Sr2+, on the other hand, stems from the preferential binding of Na+ ions at the tweezer sites, elevating the cluster's electrostatic potential and indirectly facilitating the elution of Sr2+ ions. The exceptional stability of FZU-1, along with its rapid and selective Sr2+ capture and elution capabilities, positions it as a promising candidate for large-scale nuclear waste treatment and groundwater remediation applications.

Abstract ：
Efficient electrocatalysts for the oxygen evolution reaction (OER) are paramount to the development of electrochemical devices for clean energy and fuel conversion. However, due to the complicated structures of heterogeneous electrocatalysts, it is a great challenge to elucidate the intrinsic activity of the catalytic sites on their surfaces. In this work, we report the synthesis and characterisation of a 9-Co(ii)-containing trimetric cyclic polyoxogermanotungstate cluster, K9Na3H7[Co9(H2O)6(OH)3(SeO3)2(B-alpha-GeW9O34)3]39H2O (Co9-POT), which exhibits distinct physicochemical properties and a well-defined single-crystal structure. The triangular nonacobalt(ii)-oxo cluster {Co9(H2O)6(OH)3(SeO3)2} ({Co9Se2}) in Co9-POT consists of three identical quasi-cubane {Co3O4} subunits capped by two SeO32- anions. Co9-POT exhibits electrocatalytic activity for the alkaline OER, with a turnover frequency (TOF) of the catalytically active site Co of 0.18 s-1 at an overpotential of 400 mV. In situ operational Raman and electrochemical impedance spectroscopy techniques explicitly capture the dynamic evolution of the OER process. This work provides insights into the structure-performance relationship in the OER process and the design of electrocatalysts with high atomic activity. A structurally well-defined 9-Co(ii)-containing trimetric cyclic polyoxogermanotungstate, K9Na3H7[Co9(H2O)6(OH)3(SeO3)2(B-alpha-GeW9O34)3]39H2O (Co9-POT), exhibits electrocatalytic activity for the oxygen evolution reaction (OER) in alkaline media.

Abstract ：
Electrochemical energy devices serve as a vital link in the mutual conversion between chemical energy and electrical energy. This role positions them to be essential for achieving high-efficiency utilization and advancement of renewable energy. Electrochemical reactions, including anodic and cathodic reactions, play a crucial role in facilitating the connection between two types of charge carriers: electrons circulating within the external circuit and ions transportation within the internal electrolyte, which ensures the completion of the circuit in electrochemical devices. While electrons are uniform, ions come in various types, we herein propose the concept of hybrid electrochemical energy technologies (h-EETs) characterized by the utilization of different ions as charge carriers of anodic and cathodic reactions. Accordingly, this review aims to explore the fundamentals of emerging hybrid electrochemical energy technologies and recent research advancements. We start with the introduction of the concept and foundational aspects of h-EETs, including the proposed definition, the historical background, operational principles, device configurations, and the underlying principles governing these configurations of the h-EETs. We then discuss how the integration of hybrid charge carriers influences the performance of associated h-EETs, to facilitate an insightful understanding on how ions carriers can be beneficial and effectively implemented into electrochemical energy devices. Furthermore, a special emphasis is placed on offering an overview of the research progress in emerging h-EETs over recent years, including hybrid battery capacitors that extend beyond traditional hybrid supercapacitors, as well as exploration into hybrid fuel cells and hybrid electrolytic synthesis. Finally, we highlight the major challenges and provide anticipatory insights into the future perspectives of developing high-performance h-EETs devices. (c) 2024 Science China Press.

Abstract ：
Integrating Fenton chemistry and nanomedicine into cancer therapy has significantly promoted the development of chemodynamic therapy (CDT). Nanoscale polyoxometalates (POMs), with their reversible redox properties, exhibit promising potential in developing outstanding CDT drugs by exploring their Fenton-like catalytic reactivity in tumor environments. However, such research is still in its infancy due to the challenges of acquiring POMs that are both easily prepared and possess ideal therapeutic effects, physiological solubility, biocompatibility and safety. In this work, we report the synthesis of a new crystalline antimonotungstate {Dy2Sb2W7O23(OH)(DMF)2(SbW9O33)2} (1, DMF=N, N-dimethylformamide) with gram-scale high yield via a facile "one-pot" solvothermal reaction. 1 exhibits not only a soluble and water-stable POM nanocluster, but also excellent catalytic activity for hydroxyl radical-generating Fenton-like reactions. Further biomedical studies reveal that 1 can trigger cell apoptosis and promote lipid peroxidation, exhibiting high cytotoxicity and selectivity towards B16-F10 mouse melanoma cancer cells with an IC50 value of 4.75 mu M. Especially, 1 can inhibit melanoma growth in vivo with favorable biosafety, achieving a 5.2-fold reduction in tumor volume and a weight loss of 76.0 % at the dose of 70 mu g/kg. This research not only demonstrates the immense potential of antimonotungstates in CDT drug development for the first time but also provides new insights and directions for the development of novel anticancer drugs.

Abstract ：
Polyoxometalates (POMs) have good potential for applications in different fields, including conducting materials, optics, and electrocatalysis. Of particular significance is the synthesis and development of addendum POMs. Molybdenum-oxo clusters, which are renowned for their diverse structures and electronic properties, were utilized to facilitate the synthesis of innovative materials. Herein, we employed presynthesized {XW9 Nb3O40} (X= Si/Ge) polyanions as secondary building units and different molybdenum-oxo clusters as linkers. Four new addendum POMs were constructed, including two dimeric compounds Cs10[H2(SiW9Nb3O40)2(Mo2O4C2O4)]19H2O (1) and Cs8[H4(GeW9Nb3O40)2(Mo2O4C2O4)]17H2O (2), and two tetrameric compounds Cs15(NH4)[(SiW9Nb3O40)4(Mo4O6)]42H2O (3) and Cs10K5[H(GeW9Nb3O40)4(Mo4O6)]39H2O (4). Notably, this is the first report of Mo/W/Nb ternary mixed-addendum POMs. In addition, compounds 3 and 4 facilitate the transfer of protons through extended hydrogen-bonding networks with conductivity values of 1.16 x 10-2 and 7.73 x 10-3 Scm-1 at 85 degrees C and 98% relative humidity, respectively. Furthermore, no discernible decline in conductivity was noted over the course of 10 h.
