[en] Earth-abundant metal oxides have become center of attention in the application of electrochemical energy conversion and storage. In this work, CrFeO₃ was synthesized as a new catalyst for oxygen evolution reaction (OER). The structural and chemical properties of CrFeO₃ were characterized by TEM, SEM, EDX, XRD, XPS, and BET analyses. The microscopy images reveal that CrFeO₃ have wire-like morphology, which was formed by assembly of ca. 14 nm nanocrystallites. Then, potential utility of the synthesized nanowires (NWs) as catalysts in OER has been investigated. The CrFeO₃ NW-modified fluorinated tin oxide (FTO) electrodes exhibited promising OER performance with an onset potential of 1.63 V vs RHE, overpotential of 737 mV at 10 mA cm⁻² current density, and Tafel slope of 57 mV dec⁻¹. Additionally, CrFeO₃ NWs are demonstrated to be very stable electrocatalyst during OER. The CrFeO₃ NWs present an overall electrocatalytic performance that is comparable to the one of RuO₂, and promise a great potential as an effective and affordable OER catalyst.
