Burnt to a crisp: Surface-mounted metal–organic framework (MOF) membranes were pyrolyzed to produce electrocatalytic nanomaterials with 3D nanoarchitectures and abundant catalytic sites. Cobalt contained in the MOF thin-film has a dual function; it facilitates growth of nitrogen-doped carbon nanotubes and promotes oxygen reduction, hydrogen evolution, and oxygen evolution reactions.

从表面安装的金属-有机骨架膜衍生的三维层次结构，用于增强电催化

燃烧后变脆：将表面安装的金属-有机骨架（MOF）膜热解，以生产具有3D纳米结构和丰富催化位点的电催化纳米材料。MOF薄膜中所含的钴具有双重功能。它促进了掺氮碳纳米管的生长，并促进了氧还原，氢释放和氧释放反应。
