Magnetic-field-induced rapid synthesis of defect-enriched Ni-Co nanowire membrane as highly efficient hydrogen evolution electrocatalyst

Ni-Co nanowires membrane is obtained via a fast one-step synthesis method with the assistance of rotating magnetic field, which can be directly used as binder-free and self-supported HER electrocatalyst. Owing to the abundant electroactive sites and superior charge-transfer ability, the as-obtained Ni-Co nanowire membrane exhibits superb HER performance.218
