Inorganic-MOF-inorganic approach to ultrathin CuO decorated Cu-C hybrid nanorod arrays for efficient oxygen evolution reaction

Abstract

Controllable design and synthesis is of great challenge to the micro-/nano-structures of electrode materials in heterogeneous electrocatalysis. Herein, by virtue of an inorganic-MOF-inorganic (IMI) two-stage precursor approach, novel ultrathin CuO decorated Cu-C hybrid nanorod arrays supported on carbon fiber cloth (CFC) have been developed as highly efficient electrocatalysts for the oxygen evolution reaction (OER), which exhibit a current density of 10 mA•cm–2 at an overpotential of 340 mV in 1.0 M KOH, ranking one of the best copper-based OER catalysts. Further experimental results indicate that the ultrathin cupric oxide overlayers and special nanorod arrays morphology are crucial to boosting the electrocatalytic activity, which provides a new train of thought for utilizing the low-cost and eco-friendly copper-based materials in energy storage/conversion.
