In article 1805188, 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).

氢电催化:用于氢电催化的大面积二维多晶过渡金属碳化物的自组装(Adv。Mater.50 / 2018)

在1805188号文章中,ang西宁,顾家军,林立伟和同事们开发了一种自组装过程,可以合成二维过渡金属碳化物(厚度约10 nm,横向尺寸约100 µm)。金属离子(Mo,Co,W)在明胶模板中自组织成层状纳米结构(金属水凝胶)。随后在还原性气氛(600°C)中在中等温度下进行碳化,可制得超薄的2D-TMC薄板,该薄板具有高电导率和丰富的活性位点,非常适合氢释放反应(HER)。
