Graphical Abstract

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.

Abstract

Inspired by the rapid development of metal–organic-framework-derived materials in various applications, a facile synthetic strategy was developed for fabrication of 3D hierarchical nanoarchitectures. A surface-mounted metal–organic framework membrane was pyrolyzed at a range of temperatures to produce catalysts with excellent trifunctional electrocatalytic efficiencies for the oxygen reduction, hydrogen evolution, and oxygen evolution reactions.
