Zusammenfassung:Total water splitting provides an appealing pathway for clean and sustainable energy conversion and storage. Therefore, development of a noble metal-free, efficient and robust electrocatalyst simultaneously towards the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) is still a great challenge. Herein, an ultrafast and scalable method was introduced to synthesize CoS x non-layered and freestanding nanosheets via microwave-assisted liquid-phase growth of a Co(OH) 2 precursor post-sulfurized at room temperature. The planar sheet area was up to several micrometres and exhibited an ultrathin thickness (
