Co-MOF-derived carbon nanomaterials with size-controlled FeCo alloys for oxygen evolution†
Abstract
A porous carbon material with size-controlled FeCo alloys and carbon nanotubes (CNTs) was obtained from pyrolysis of a Co-based metal–organic framework (MOF), followed by the Fe3+-etching process and CNT growth. This catalyst (CoOF-1-FeCoNC-CNT) displayed satisfactory OER activity, attributed to its large specific surface area, improved electrical conductivity, and the synergistic effect of the bimetallic FeCo alloy.
