The urea electro-oxidation reaction (UOR) is emerging as a new energy conversion technology and promising method for alleviating water eutrophication problems. However, rationally designed structure of the electrode materials urgently required to achieve high UOR performance. Herein, P-doped MOF-derived Co3O4 nanowire arrays grown on nickel foam (P-Co3O4/NF) are successfully synthesized via growth Co-MOF subsequent calcination followed by phosphorization treatment. Owing optimized electronic structure, as-prepared P-Co3O4/NF composite exhibits much higher electrocatalytic performance than undoped Co3O4/NF sample. Beyond this, meticulous one-dimensional three-dimensional skeleton contribute enhanced activity stability toward UOR. As result, displays low overpotential 1.419 V vs. RHE at 50 mA cm−2, small Tafel slope 82 mV dec−1, well favorable long-term over 65,000 s in 1.0 M KOH with urea. This work opens avenue designing non-precious electrocatalysts high-performance reactions.
