%X Herein, NixFe1–xOOH/NiFe/NixFe1–xOOH
sandwich-structured nanotube arrays (SNTAs) supported on carbon fiber
cloth (CFC) (NixFe1–xOOH/NiFe/NixFe1–xOOH SNTAs–CFC) have been developed as flexible
high-performance oxygen evolution reaction (OER) catalysts by a facile
in situ electrochemical oxidation of NiFe metallic alloy nanotube
arrays during oxygen evolution process. Benefiting from the advantages
of high conductivity, hollow nanotube array, and porous structure,
NixFe1–xOOH/NiFe/NixFe1–xOOH SNTAs–CFC exhibited a low overpotential of ∼220
mV at the current density of 10 mA cm–2 and a small
Tafel slope of 57 mV dec–1 in alkaline solution,
both of which are smaller than those of most OER electrocatalysts.
Furthermore, NixFe1–xOOH/NiFe/NixFe1–xOOH SNTAs–CFC exhibits excellent stability
at 100 mA cm–2 for more than 30 h. It is believed
that the present work can provide a valuable route for the design
and synthesis of inexpensive and efficient OER electrocatalysts.
