摘要
It is desirable to exploit cost-effective and earth-abundant catalysts for the oxygen evolution reaction (OER) in developing electrochemical energy conversion and storage technologies. Here we report a facile hydrothermal synthesis of NiMo04 nanorods as active and stable OER catalyst in alkaline condition. The prepared NiMoO_4 nanorods exhibit a considerably low overpotential of 340 mV at the current density of10 mA/cm~2 and a low Tafel slope of 45.6 mV/dec, which is comparable to the benchmark Ru02.Furthermore, the performance of NiMoO_4 significantly surpasses binary NiO and MoO_3 oxides due to enhanced charge transfer and promoted formation of catalytically active Ni~(3+) species. The results highlight the importance of designing ternary oxides in oxygen electrocatalysis.
