Jul 26, 2017· Nanostructured Fe–N–C materials represent a new type of "platinum-like" non-noble-metal catalyst for various electrochemical reactions and organic transformations. However, no consensus has been reached on the active sites of the Fe–N–C catalysts because of their heterogeneity in particle size and composition. In this contribution, we have successfully prepared atomically dispersed ...

Zeolitic imidazolate framework - Wikipedia

Zeolitic imidazolate frameworks (ZIFs) are a class of metal-organic frameworks (MOFs) that are topologically isomorphic with zeolites.ZIFs are composed of tetrahedrally-coordinated transition metal ions (e.g. Fe, Co, Cu, Zn) connected by imidazolate linkers. Since the metal-imidazole-metal angle is similar to the 145° Si-O-Si angle in zeolites, ZIFs have zeolite-like topologies.

Advanced Energy Materials: Vol 11, No 12

Mar 25, 2021· New cost‐effective rare‐earth‐metal‐free halide superionic conductors for all‐solid‐state batteries are developed. In contrast to poorly Li + ‐conductive cubic close‐packed monoclinic Li 2 ZrCl 6 produced by heat‐treatment, ball‐milling leads to an hexagonal close‐packed structure and high Li + conductivity (0.40 mS cm −1).
