Here, we proposed a strategy of building multiple affinities in a robust Ni(bdc)(dabco)0.5 for highly effective one-step C2H4 purification from C3H6/C2H4 mixture in MTO and steam cracking of naphtha products. Due to nonpolar pores edited by available O binding sites with suitable pore restriction and high BET surface area, Ni(bdc)(dabco)0.5 shows not only one of the highest C3H6 uptake (80.6 cm3(STP) g-1) at 0.1 bar and excellent C3H6 uptake (148.8 cm3(STP) g-1) at 1.0 bar but also top-level C3H6/C2H4 selectivity (10.7) and separation potential (115.3 cm3(STP) g-1) at 298 K and 1.0 bar. Meanwhile, the C3H6/C2H4 uptake ratio (10.9) exhibits a record value at 0.1 bar with a lower (26.7 kJ mol-1), breaking the trade-off of C3H6/C2H4 separation and setting a new benchmark. Theoretical simulation and in situ FT-IR unveiled that the nonpolar pore with rich O binding sites supplies stronger multiple supramolecular affinities with C3H6 over C2H4. Breakthrough tests prove its utter separation performance of the C3H6/C2H4 with good recyclability, offering one of the highest dynamic C3H6 uptake and C2H4 productivity (101.2 and 57.3 cm3(STP) g-1). The MOF is easy to synthesize on a gram-scale from cheap reagents. Ni(bdc)(dabco)0.5 fulfills a benchmark combination of good separation performance, great stability, good renewability, and easy scalability, which awards it a great prospect for industrial C2H4 purification.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"30 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144640419","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}

The MXene nanofiber (MXene-NF) is reconstructed from the MXene nanosheet accompanying the formation and extension of cracks, which avoids the self-stacking of MXene and stimulates the dispersion of Ir metal catalysts. The existence of electron transfer and the strong electrostatic interaction between the Ir species and the conductive MXene substrate endows the as-prepared catalyst with superior HER activity in the alkaline media, with an ultralow overpotential of 15.8 mV to reach a current density of 10 mA cm<small>^-2</small>, remarkably high mass activity about 4.8-fold greater than the commercial Ir/C catalyst, and an excellent long-term stability. As evidenced by the density functional theory calculations, MXene-NF supported Ir NCs exhibit a hydrogen adsorption for free energy (ΔG<small>_H*</small> = -0.35 eV) closer to thermodynamic neutrality, significantly boosting the catalytic kinetics.

Herein, a Cu/corncob biochar honeycomb composite was synthesized using a facile impregnation/calcination method. The corncob biochar exhibited a honeycomb morphology with high specific surface area and abundant adsorption sites due to its porous surface structure. The localized heating and the generation of high-energy hot electrons were facilitated by the localized surface plasmon resonance (LSPR) induced by Cu nanoparticles. Consequently, the photo-thermal catalytic reduction of CO2 was enhanced, significantly contributing to the high conversion of CO2 to methanol in pure water. Notably the 5% wt Cu/corncob biochar demonstrated a CO2 adsorption capacity of 52.59 cm3/g under conditions of 25 ℃ and 1 bar. Simultaneously, under full-spectrum irradiation, Cu nanoparticles catalyzed the formation of key intermediates *COOH and *CH3O species during the CO2 conversion process, resulting in a high CH3OH yield of 63.3 μmol/g.

Unlocking these applications requires the development of efficient ammonia oxidation catalysts. Building on recent work with a fluorinated Cu(I) β-diketiminate catalyst for homogeneous ammonia oxidation, we present the first examples of hybrid electrodes employing first-row metal complexes and supramolecular anchoring for heterogeneous ammonia oxidation. In this study, we developed innovative synthetic methodologies to produce a family of β-diketiminate ligands and complexes. Some analogues clarified the role of each functional group in the original ligand, while others incorporated moieties designed to facilitate immobilization on graphitic surfaces via CH-π and π-π interactions. These structural modifications not only broadened the scope of ligand design but also advanced our understanding of their roles in catalysis and immobilization. Unexpectedly, all synthesized Cu complexes, including the previously reported catalyst, formed an equilibrium with [CuI(NH3)4]+ or [CuII(NH3)4]+ in the presence of ammonia, leading to ligand dissociation and subsequent catalyst deactivation. Despite these challenges, we demonstrated that anchoring these complexes is feasible and confirmed that heterogeneous ammonia oxidation is possible with this system. This work represents a pivotal step toward the construction of ammonia oxidation systems based on earth-abundant metals, highlighting the promise of Cu β-diketiminate complexes. Addressing the challenges of ligand loss and catalyst stability will pave the way for robust and efficient systems, driving advancements in sustainable ammonia-based energy technologies.","PeriodicalId":79,"journal":{"name":"Inorganic Chemistry Frontiers","volume":"14 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144622687","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, we have constructed a Z-scheme BAIO/C3N4 heterojunction by in situ growing Ba2AgIO6 (BAIO) on the surface of C3N4 nanosheets. Under visible light irradiation, the optimal sample, with a BAIO:C3N4 mass ratio of 1:1.5, exhibited a remarkable H2O2 yield of up to 535.9 μmol g-1 h-1, which is 8.8 times higher than that of pure C3N4. This enhancement is attributed to the improved charge separation and migration efficiency facilitated by the enhanced internal electric field (IEF) in BAIO/C3N4 heterojunction. Furthermore, the heterojunction altered the O2 adsorption configuration to the Yeager-type, promoting a more efficient and selective direct one-step 2e- ORR for H2O2 production.

In general the extraction of transplutonium actinides has not been extensively explored, but is essential to fundamental chemical understanding and separation schemes. A popular <em>N,O</em>-donor extractant, phenanthroline diamide (DAPhen), has incurred interest for <em>f</em>-element separations due to numerous positive qualities as an extractant. DAPhen ligands are stable in molar concentrated acids and have a pre-organized binding mode that encourages faster complexation. Additionally, the amide moieties can be functionalized to tune interactions between metals and ligands. In this work, solvent extraction experiments were completed using a derivative of the DAPhen extractant in nitrobenzene that revealed selectivity for multiple An(III) (An = Am, Cm, Bk, Cf) metals in comparison to Eu(III). The extraction of all surveyed An(III) cations was effective. Surprisingly, the degree to which each An(III) cation was extracted was not periodic. Extraction was most effective for Am(III), intermediate for Cf(III) and Bk(III), and lowest for Cm(III). To provide additional insight into the extraction process, we characterized the corrdiantion chemistry between Am(III) and numerous Ln(III) cations (Pr(III), Nd(III), Tb(III), Lu(III)) with TEtDAPhen. Lanthanide speciation and stability constants were measured using UV-Visible spectroscopy for multiple Ln(III) metals (Nd(III), Eu(III), Gd(III)). Those experiments showed increasing stability constants from Nd(III) – Gd(III) and that the metal-to-ligand stoichiometry was one-to-one.
