Facile synthesis of ultrathin Co(OH)NO nanosheets and their electric-field assisted transformation into a defect-rich CoO/CoOOH heterostructure for efficient oxygen evolution
Facile preparation of low-cost electrocatalysts for an efficient oxygen evolution reaction (OER) is significant but remains a big challenge. Herein, a novel and facile strategy for transforming intrinsic non-stoichiometric ultrathin Co 5 (O 9.48 H 8.52 )NO 3 nanosheets into oxygen-vacancy enriched C...
