英文摘要	The electrocatalytic oxygen evolution reaction (OER) plays a critical role in sustainable energy conversion and storage, but OER is severely hampered owing to the lack of highly efficient catalysts. Here, we report an efficient electrocatalyst, with NiO/Co3O4 nanoparticles decorated on nitrogen -doped carbon (NiO/Co3O4@ NC). Abundant high -valence Ni3+ and Co3+ species were observed on the surface of the hybrid due to the strong NC-metal oxide and NiO-Co3O4 interactions. This unique structure leads to excellent OER performance, delivering a very low overpotential of 240 mV(&10 mA"cm(-2) on glassy carbon and 200 mV(&10 mA"cm(-2) on Ni foam in KOH and having a turnover frequency (@350 mV overpotential) 6 and 16 times higher than that of IrO, and RuO2, respectively.
