Mesoporous NiO with a single-crystalline structure utilized as a noble metal-free catalyst for non-aqueous Li–O2 batteries

Porous-structured NiO nanosheets, synthesized by means of a facile alcohol-thermal method, were utilized as a noble metal free catalyst for non-aqueous Li–O₂ batteries. The NiO showed good activity for the decomposition of Li₂O₂ and Li₂CO₃.
