Oxidative atmosphere-driven formation of single-phase spinel CuRh 2 O 4 nanofibers for alkaline water oxidation

Year: 2026

Type: article

Abstract: Cu–Rh bimetallic single-phase spinel oxide nanofibers were synthesized via electrospinning followed by post-annealing under precisely controlled oxidative environments. By systematically tuning the O 2 concentration in He carrier flow during the annealing process, the optimal atmosphere was identified to produce phase-pure CuRh 2 O 4 . The as-prepared CuRh 2 O 4 nanofibers exhibited excellent electrocatalytic performance toward the oxygen evolution reaction in 1.0 M NaOH ( aq ), highlighting the importance of atmosphere-controlled thermal treatment for engineering high-activity spinel oxide electrocatalysts.
