Summary: Metal-organic frameworks (MOFs) are porous, crystalline materials with various potential applications. In this study, we demonstrate a solvent-free method that can directly produce high-quality MOFs by combining low-melting metal halide salts with different linkers. These ionothermal-synthesized MOFs have comparable porosity to those prepared under traditional solvothermal conditions. Furthermore, we report the successful synthesis of two frameworks that cannot be directly prepared using solvothermal methods. Overall, this user-friendly method holds great promise for the discovery and synthesis of stable metal-organic materials.

Summary: Zinc oxide (ZnO) nanostructures with nanoparticle morphology were synthesized using [OMIM]Br ionic liquid as a solvent and template by ionothermal method. The effect of temperature on the properties of ZnO nanostructures was investigated, and it was found that higher annealing temperature in the ionic liquid resulted in ZnO nanoparticles with increased crystalline structure and enlarged band gap. The Z-scan technique was used to study the nonlinear optical (NLO) responses of the samples, and it was observed that ZnO samples prepared at higher temperatures and longer exposure time in [OMIM]Br ionic liquid exhibited greater NLO responses compared to Cu-doped ZnO.

Summary: The development of high capacity and stable cathodes is crucial for the successful commercialization of aqueous zinc-ion batteries. This study proposes the use of hydrated intercalation to promote reversible insertion and extraction of zinc ions within host materials by designing a matching electrode. The results show that the as-prepared electrode (NHVO@CC) demonstrates fast and reversible intercalation of hydrated zinc ions, resulting in a high capacity of 517 mAh g(-1) and excellent electrode stability. Additionally, the flexibility of the NHVO@CC electrode enables the achievement of a quasi-solid-state battery with favorable electrochemical behavior under various bending states. The proposed hydrated cation direct insertion/extraction provides an efficient approach for developing high-performance positive electrodes for aqueous batteries.

Summary: In this study, a covalent triazine framework (CTF) was used as a coating layer for zinc anodes to address the problems of uncontrollable dendrite growth and side reactions. The CTF layer provided uniform transport paths for Zn2+ ions and effectively separated the zinc anodes from the electrolyte to prevent side reactions. Additionally, the triazine ring in the CTF acted as zincophilic sites to enhance Zn deposition kinetics. The CTF-protected zinc anode exhibited a significantly longer cycle lifespan and lower voltage polarization compared to bare zinc anodes.

Summary: Ordered porous functional materials, including microporous metal-organic frameworks and mesoporous silica, have been extensively studied for their unique physiochemical properties and broad potential applications. However, the lack of ordered macroporous materials, especially those with high crystallinity, hinders the extension of these advantages to a larger scale. Through a co-sacrificial template sequential pyrolysis process, a three-dimensionally ordered macroporous framework material, OMGCs, has been developed, consisting of well-crystallized graphenic carbon and uniformly dispersed metallic nanocrystals. These OMGCs exhibit a low-temperature formation mechanism and may greatly expand the family of ordered porous framework materials for emerging applications.
