Here, we report a MgO-assisted solvothermal strategy for synthesizing hexagonal close-packed (HCP) Ru nanospheres from Ru(acac)<small>₃</small> in isopropanol, in which MgO templates modulate the crystallization pathway to preferentially expose the (100) and (002) facets while suppressing the (101) facet. This facet-selective growth leads to the formation of well-defined crystalline domains with abundant low-coordination edge sites and oxygen vacancies at domain boundaries. Such domain-induced surface reconstruction gives rise to edge-rich chemistry – a catalytic environment characterized by enhanced interfacial charge transfer, strengthened water adsorption, and optimized hydrogen binding at under-coordinated Ru<small>⁰</small> sites. Mechanistic studies, including <em>in situ</em> Raman spectroscopy, reveal that the edge-enriched Ru<small>_domains</small> promotes earlier onset of hydrogen adsorption and accelerates H<small>₂</small> evolution by facilitating both the Volmer and Heyrovsky steps.

Due to the modular nature and molecular tunability of the metal node-linker coordination in MOFs, they are considered competent hosts for secondary materials in their extensive pore channels. Modifications of the metal nodes or ligand functionalisation in MOFs can improve the anchoring ability of nanoparticles, effectively enhance the nanoparticles’ stability, and mitigate the inherent nature of nanoparticles to aggregate. In this review, the synthetic strategies (“ship-in bottle”, “bottle-around-ship”, and one-pot) and novel characterisation techniques of nanoparticle-MOF (NP-MOF) composites are discussed in detail. The precise determination of nanoparticle-MOF coordination is crucial to shed light on the structure-activity relationships of the catalytic composites. Recognising the synergistic properties of MOFs and metallic nanoparticles, we also explore recent advancements in NP-MOF composites with a special focus on zirconium-based MOFs for catalytic applications within the last five years. Therefore, we aim to aid the reader in evaluating recent advancements concerning the chemistry of nanoparticles and MOFs as catalysts and highlight areas that still require attention in future works.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"115 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144678073","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 development two lysosome-targeted oncosis inducers based on Ru(II) complexes (Ru1 and Ru2) with different ancillary ligands for photodynamic anticancer therapy, which exhibited excellent lysosome-targeting capabilities, high singlet oxygen quantum yield and enhanced photodynamic therapy (PDT) activities under acidic conditions. The Ru(II) complexes, acting as pH-responsive photosensitizers (PSs), could selectively target lysosomes, disrupt their membrane integrity, and induce the release of lysosomal contents into the cytoplasm. With the depletion of ATP and the release of Ca2+ from lysosomes into the cytoplasm, oncosis-specific proteins such as porimin and calpain are activated, ultimately leading to oncotic cell death. The photodynamic antitumor efficacy of the Ru(II) complexes was comprehensively assessed through in vitro studies, cellular assays, and 4T1 tumor-bearing mice model. Interestingly, Ru2 could selectively target and kill cancer cells under light irradiation while exerting minimal effects on normal cells. This research not only offers valuable theoretical insights for designing highly efficient PSs to enhance the effectiveness of PDT but also proposes a strategy for developing oncosis inducers through lysosomal damage.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"14 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144678074","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}

However, the scarcity of high-performance ORR electrocatalysts has emerged as a crucial bottleneck that restricts the enhancement of energy conversion efficiency in these sustainable electrochemical systems. In this study, we employ a self-template strategy for the precise preparation of copper and iron bimetallic dual-atom active sites anchored on metal-organic-framework (MOF)-derived highly poriferous carbon nanosheets. This bimetallic diatomic catalyst (CuFe-NCN) possesses highly homogeneous and atomically precisely dispersed active sites, which significantly enhances its catalytic activity for the ORR throughout an extensive pH range. It exhibits outstanding electrocatalytic activity for the ORR in alkaline, neutral, and acidic solutions, outperforming commercial Pt/C catalysts. Specifically, the half-wave potentials are 0.95 V in alkaline solution, 0.79 V in neutral solution, and 0.80 V in acidic solution. To explore the bifunctional properties of the electrocatalyst, its oxygen evolution reaction (OER) performance was studied. For CuFe-NCN, the potential is 310 mV at a current density of 10 mA cm-2, which is superior to that of the commercial RuO2 (440 mV). When utilized in the assembly of zinc-air battery (ZAB) devices, it functions steadily at 5 mA cm-2 for a period of 910 h and reaches a power density peak of 281 mW cm-2. Furthermore, the assembled flexible zinc-air battery maintains stable operation for 200, 150, and 150 h at 0.5, 1, and 2 mA cm-2, respectively.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"8 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144664387","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}

To address this issue, we designed a novel dual-mode broadband NIR phosphor Mg5Ga2Sn2O12:Cr3+, Ni2+ (MGSO) based on an energy transfer strategy. The optimized MGSO:0.1Cr3+, 0.01Ni2+ shows ultra broadband NIR emission from 700 to 1650 nm under 424 nm excitation.

The internal and external quantum efficiencies of MGSO:0.1Cr3+, 0.01Ni2+ are 68.2% and 30%, respectively. To further investigate its application prospect, a novel NIR light source was created by encapsulating MGSO:0.1Cr3+, 0.01Ni2+ with a 440 nm blue light LED.
