The essential issue in Fenton reaction was the high efficient catalyst design, and the yolk@shell structure was usually functioned as the nanoreactor to boost activation efficiencies of H2O2 (or peroxymonosulfate (PMS)). In typical, a yolk@shell nanoreactor was constructed from a hollow shell and a movable core, which could transfer Fenton reaction performed in the bulk solution to the internal cavity. Benefiting from the confinement effect, the collision opportunity among various reactants was increased, the degradation rate was accelerated, the H2O2 (or PMS) utilization efficiency was boosted, the environmental tolerance of catalysts was improved, and the metal leaching was lowered. Therefore, yolk@shell nanoreactor provided an ideal platform for heterogeneous Fenton reaction. In addition, many methods could be adopted to tailor the yolk@shell nanoreactor for better catalytic performance, and this inspired researchers to design nanoreactor with optimized compositions and novel structures. At present, many reviews on either preparation and application of yolk@shell nanoreactor or recent development of heterogeneous Fenton reaction were reported, however, the strategies to improve the Fenton reaction based on yolk@shell nanoreactor have not been detailed discussed. This review have illustrated the recent progress on yolk@shell nanoreactor for heterogeneous Fenton reaction, and provided an comprehensive information on catalyst design, catalytic performance, catalytic mechanism, catalyst advantage, catalyst improvement method, aiming at catalyst with better performance.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"29 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144578027","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, it suffers from the Jahn-Teller (J-T) effect, transition metal migration, and irreversible oxygen loss, and the irreversible phase transition caused by these problems can lead to the deterioration of its crystal structure and the rapid decay of its capacity, which hinders its practical application. Herein, Cu/Ti co-doping P2-Na0.67Fe0.3Mn0.5Cu0.15Ti0.05O2 (NFMCTO) cathode material were prepared by sol-gel method. The doping of Ti4+ reduces the content of Mn3+, mitigates the J-T effect as well as the dissolution of Mn2+, and furthermore also excites the lattice oxygen oxidation reduction (ORR) to improve the capacity. Meanwhile, the introduction of highly reducing Cu2+ inhibits the migration of Fe3+ and realizes the high multiplicity performance of the material by promoting electron-hole separation. Under the combined effect of Cu and Ti, NFMCTO shows a high initial discharge capacity of 207.2 mAh g-1 at a current density of 20 mA g-1, and superior rate performance (119.1 mAh g-1 at 400 mA g-1). Meanwhile, it still has 124.2 mAh g-1 capacity after 100 cycles at 200 mA g-1, and the capacity retention rate is increased from 51.1% to 77.1%. The In-situ XRD results confirm the reversible structural evolution of the modified material and alleviated phase transitions. The In-situ EIS and GITT results also indicate that NFMCTO has improved Na+ ion transfer kinetics through Cu/Ti synergism, which corresponds to the excellent rate performance of the material. Finally, the testing of the NFMCTO//HC full cell further confirms the promising application of NFMCTO. This work confirms the necessity of co-doping in doping modification, and the co-doping synergistic strategy provides a new idea for the subsequent study of Fe/Mn-based cathode materials on suppressing the J-T effect and irreversible oxygen loss under high voltage.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"39 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144568968","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 work, we propose a novel mechanism for urea synthesis on dual transition metal atom-anchored graphitic carbon nitride (TM2@g-C₂N) through the co-reduction of CO and N2O using density functional theory (DFT) calculations. By employing a three-step screening strategy, we systematically investigated homonuclear dual-atom pairs embedded in g-C₂N for their catalytic activity, selectivity, and stability. Our results demonstrate that dual-atom pairs can be stably embedded into the hollow regions of g-C2N via nitrogen coordination, exhibiting superior electrochemical stability. In addition, dual-metal atoms significantly enhance the electrical conductivity of g-C2N, facilitating charge transfer. Notably, Fe2 and Co2@g-C2N emerge as promising candidates for electrocatalytic urea synthesis via CO and N2O coupling, with limiting potentials (UL) of −0.27 V and −0.35 V, respectively, following alternative mechanism. Meanwhile, Nb2@g-C2N is identified as an excellent catalyst for N2O reduction to NH3, achieving UL of −0.34 V within mixed mechanism. We further reveal that stable *NCON adsorption promotes subsequent hydrogenation steps, lowering the limiting potential for urea formation on Fe2@g-C2N. The adsorption of N2O and formation of *NCON on TM2@g-C2N are identified as critical steps, where the relatively strong interactions between active sites and intermediates correlate with high catalytic activity. This work expands the potential of dual-atom catalysts in enabling efficient urea production via N2O and CO co-reduction.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"46 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144566368","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, further research on their relationship is still needed, especially for their scintillation properties. In this work, four novel 0D OIMnHs (ted-Cn-ted)MnBr4 (ted = triethylenediamine, n = 7-10) were synthesized using tailored (ted-Cn-ted)2+ cations. Benefiting from the large molecule size and rigidity of the cations, the [MnBr4]2− units are effectively separated, bringing the compounds about high PL quantum yields (PLQYs) and light yields. More importantly, after analyzing the synthesized compounds and the reported samples, the positive correlation between the shortest Mn-Mn distance in these OIMnHs and their PLQYs and light yields is unveiled, and OIMnHs with distances in the 9-11 Å range exhibit both superior PLQYs and light yields. Besides, a WLED device is fabricated employing (ted-C10-ted)MnBr4, achieving high-quality illumination with 94% National Television Standards Committee (NTSC) color gamut coverage.

In this study, MnOx nanoparticles were deposited onto the surface of BiFeO3 nanosheets via a photodeposition method, and their promoting effects in piezocatalytic and piezo-photocatalytic reactions were systematically investigated. The synthesized MnOx/BiFeO3 composites exhibited enhanced catalytic performance in RhB degradation. In the piezocatalytic system, the optimized MnOx/BiFeO3 catalyst achieved a degradation rate constant of 0.78 h⁻¹, approximately 4.6 times that of pure BiFeO3. Under simultaneous ultrasonic vibration and light irradiation, the rate constant further increased to 1.4 h⁻¹, representing 1.8 times and 1.4 times the rates observed under individual piezocatalytic and photocatalytic conditions, respectively. Comprehensive characterization techniques were employed to elucidate the mechanism behind the enhanced performance. The results reveal that MnOx modification induces interfacial stress, enhancing the piezoelectric response of BiFeO3. Moreover, an S-scheme heterojunction is formed at the MnOx/BiFeO3 interface, wherein holes in the valence band of BiFeO3 recombine with electrons from MnOx, effectively promoting charge separation and transport while preserving the strong redox capability of both charge carriers. The synergistic piezo-photocatalytic effect of MnOx/BiFeO3 is attributed to the global piezoelectric potential of BiFeO3, which extends the spatial range of interfacial charge separation within the S-scheme heterojunction. Additionally, the high-density photogenerated electron-hole pairs produced under light irradiation effectively supplement the intrinsic charge carriers. This study not only clarifies the potential mechanism by which MnOx functions as a hole-trapping cocatalyst, but also highlights the unique advantages of S-scheme heterojunctions in the field of piezo-photocatalysis, offering valuable insights for the design of efficient piezocatalytic materials.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"11 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144533747","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}
