Abstract
- Vacancy enriched electrocatalysts are crucial in enhancing the catalytic activity for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) through a defect engineering. Herein, oxygen vacancies enriched Co 3 O 4 nanoflowers with single layer porous structures are made to study their catalytic activity toward water splitting. The as-synthesized defects enriched Co 3 O 4 presents flowers-like nanostructures and possesses high specific surface area (84 m2 g−1) with uniform pore size (4 nm). On behalf of the unique morphology and electronic structure, the Co 3 O 4 nanoflowers display enhanced HER and OER performances compared with commercial Co 3 O 4 nanoparticles (∼50 nm). In addition, it still presents good catalytic without remarkably decay in potential over 9 days. • Oxygen vacancies enriched Co 3 O 4 nanoflowers with single layer porous structures are synthesized. • The as-synthesized electrocatalyst displays superior water splitting performances. • The enhanced performances could be attributed to the unique morphology and electronic structure. • The catalytic activity is maintained for at least 9 days without remarkably decay.
