英文摘要	Introducing oxygen vacancies and reducing size of NPs are two effective strategies to enhance the electrocatalytic performance of transition metal oxides for oxygen evolution reaction (OER). Herein, NiO NPs with ultrasmall size (asymptotic to 2.1 nm) and rich oxygen vacancies (NiO-LFL) are prepared by laser fragmentation of bulk NiO NPs in water. The ultrasmall size of NPs enable more active sites to be exposed. And the abundant oxygen vacancies in NiO greatly improve the intrinsic activity and electrical conductivity. Benefit from these advantages, NiO-LFL NPs display a remarkable OER activity and stability in 1 M KOH, which is superior to the state-of-the-art RuO2 catalyst.
