Stable and highly active catalytic cathodes constitute a pivotal factor in driving the commercialization of Li-CO2 batteries regard to reactant activation and decomposition of discharge products timely. Herein, a ceria-based high-entropy oxides (HEOs), denoted as CeFeCoNiMnOx, is synthesized by exploiting the exceptional heterogeneity-tolerant properties of fluorite-structured cerium oxide (CeO2). Leveraging the robust structural and chemical stability of the CeO2 framework, the encapsulated polymetallic active sites within the oxide are effectively integrated, thereby enhancing the electrochemical performance of the cathode. The resultant Li-CO2 battery demonstrates remarkable discharge voltage at 2.98 V, substantial discharge capacity of 11128 mAh g-1 as well as exceptional cycling stability of 171 cycles based on the HEOs at current rate of 100 mA g-1. Benefiting from the effective decomposition of discharge products by the synergistic action of multiple active sites, the cell exhibits a leading low overpotential at 0.91 V. The innovative design approach of utilizing fluorite-structured CeO2 as a substrate for the integration of multiple active sites and the subsequent construction of HEOs broadens the spectrum of catalytic cathodes for Li-CO2 batteries.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"32 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992049","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 paper, self-supporting layers containing high-entropy materials (HEMs) with adsorption-catalytic-conversion integrated functions were applied for the first time for separator modification of Zn-I2 batteries. Benefiting from the multi-elemental composition of HEMs, the widely distributed d-band centers improve the bonding between metals and molecules to realize the reduced adsorption energies to reactants or intermediates, giving the HEMs substantial highly active sites as adsorption and catalytic centers. This allows the polyiodides to be chemically anchored and catalytically converted by the modified layer once they are formed. The entire iodine conversion reaction proceeds efficiently without polyiodide shuttle and dissolution. As a result, satisfactory cycling stability was achieved. HEM is proposed as separator modification materials with adsorption-catalytic-conversion synergies, presenting an effective strategy and new inspiration for realizing high-performance Zn-I2 batteries.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"10 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992083","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 poor selectivity and toxicity problem of current GPX4 covalent inhibitors have hampered the development of GPX4-targeted cancer therapy. Benefiting from the reactive oxygen species (ROS)-initiated activation of N-alkylaminoferrocenes (NAAF), a series of NAAF-appended GPX4 inhibitors have been developed as novel ferroptosis-inducing prodrugs, particularly RSL3-NAAF hybrid I-1 and ML162-NAAF hybrid II-1. These two complexes displayed comparable anticancer activities with those of their precursor compounds, but with superior ferroptosis selectivity and exceptional safety profiles on normal cells. In this study, the efficient release of the GPX4 inhibitor from II-1 under high ROS conditions along with its significant ROS-inducing ability at both the molecular and cellular levels have been evidenced, leading to its potent inhibition on GPX4 and remarkable ferroptosis inducing potency. These data indicate promising aminoferrocene-based anticancer agents for further evaluation. The effectiveness of NAAF-based prodrug strategy may not only advance the development of ROS-responsive prodrugs for ferroptosis-related anticancer treatments, but also highlight the significance of metallocene-containing bioorganometallics for potential disease therapies.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"57 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142990681","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}
