The carboxylation/cyclization of alkynes catalyzed by Cu or Ag nanoparticles (NP) is one of the green pathways for CO2 utilization. However, these reactions are often limited by harsh conditions, as well as the migration, aggregation, and leakage of metal NP during the reaction. Herein, the AgxCuy heterostructure alloy NP are surrounded by a porous metal–organic framework, forming core–shell AgxCuy@ZIF-8 catalysts. Thanks to the light-to-heat capability, these catalysts exhibited excellent catalytic activity in converting various alkynes and CO2 to alkynyl carboxylic acids and promoting the cyclization reactions of propargyl amines with CO2 under ambient conditions using blue LED irradiation. The remarkable catalytic activity of Ag1Cu1@ZIF-8 is attributed to the optimized electronic states of Ag and Cu NP, as well as the core–shell structure that enhances photothermal effects around the catalytic center. In addition, the ZIF-8 shell not only improves the substrate transport but also inhibits the aggregation, migration, and loss of alloy NP cores during the reaction, contributing to enhanced cycling performance compared to unencapsulated Ag1Cu1 NP. The catalytic reaction mechanisms were disclosed by a variety of spectral characterizations, control experiments, and DFT calculations.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"35 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143849906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work includes the spectroscopic and theoretical characterization of an end-on RuIII-superoxo complex (3), together with the crystallographic characterization of a side-on RuIV-peroxo complex (4) which should be in equilibrium with 3 in an aqueous solution. The formation of the RuV-oxo intermediate as a responsible species for the water oxidation was supported by a square wave voltammogram of 1 in an aqueous solution, showing an oxidation wave at +1.52 V (vs NHE) which is accessible with use of excess CAN through an electron-transfer equilibrium. Kinetic analysis and isotope labeling experiments supported a water nucleophilic attack (WNA) mechanism in the water oxidation. The stability of 3 as a product of WNA allowed us to detect it in aqueous solution. The diamagnetic character of 3 enabled the detailed kinetic investigation of O2-releasing from the intermediate to determine activation parameters. Herein, a new insight was gained into the O2 release from 3 as the final step of water oxidation by the mononuclear Ru catalyst.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"11 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143849909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using crude ferronickel derived from the smelting of laterite ores to produce these precursors enables the efficient valorization of Fe, Ni, and Co. However, the limited leaching efficiency of ferronickel necessitates strategies to enhance its acid leaching properties. This study proposes a synergistic approach using a roasting atmosphere and temperature to activate water-quenched ferronickel. With increasing roasting temperature, the face-centered cubic (FCC) Ni–Fe phase transformed into the body-centered cubic (BCC) phase. When the temperature exceeded 800 °C, however, the newly formed BCC phase reverted to the FCC phase in a N2 atmosphere. Carbon in ferronickel could be removed by roasting in a CO2 atmosphere, thereby preventing phase reversion. After roasting at 800 °C for 1 h under a N2 atmosphere, the leaching efficiencies of Ni, Co, and Fe were 92.88, 91.88, and 89.20%, respectively, with the unleached portion consisting of cementite and an unconverted FCC phase. Following roasting at 1000 °C for 1 h in a CO2 atmosphere, the corresponding leaching efficiencies increased to 99.65, 99.37, and 96.75%, respectively, achieving near-complete leaching due to phase elimination.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"37 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143849910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although chelation therapy has been considered the only practical treatment in emergencies, current clinical chelators show only limited efficacy for uranium. Herein, a recently designed lacunary selenotungstate polyoxometalate (Se6W45) was demonstrated as an effective therapeutic agent. In this construct, the open site in Se6W45 provides a suitable uranium binding environment, resulting in the selective removal of uranium from kidneys (85.87%) and femurs (39.81%) with an extremely low ligand/metal ratio of only 4:1. The redox active sites in Se6W45, primarily the incorporated selenium, were able to reduce the intracellular reactive oxygen species (ROS) to normal levels in NRK-52E cells exposed to uranium. This approach overcomes the disadvantages of the excessive use of current chelating ligands in the range from 100- to 1000-folds, avoiding the consequential depletion of heterogeneous cations, dysfunction of proteins, and/or acid–base imbalance. More importantly, it provides a synergistic antidotal therapy for uranium in reducing radiation damage and chemical toxicity.","PeriodicalId":40,"journal":{"name":"Inorganic Chemistry","volume":"61 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143849907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
