Abstract

Abstract : In article1805188, Xining Zang, Jiajun Gu, Liwei Lin, and co‐workers develop a self‐assembly process to synthesize two‐dimensional transition metal carbides (≈10 nm thickness and ≈100 µm lateral size). The metal ions (Mo, Co, W) self‐organize within a gelatin template into a lamellar nanostructure (metallo‐hydrogel). Subsequent carbonization at moderate temperatures in a reducing atmosphere (600 °C) yields ultrathin 2D‐TMC sheets with high conductivity and rich active sites ideal for the hydrogen evolution reaction (HER).
