本文主要研究内容
作者（2019）在《Nanostructured NiMoO4 as active electrocatalyst for oxygen evolution》一文中研究指出：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 NiMoO4 nanorods exhibit a considerably low overpotential of 340 mV at the current density of10 mA/cm2 and a low Tafel slope of 45.6 mV/dec, which is comparable to the benchmark Ru02.Furthermore, the performance of NiMoO4 significantly surpasses binary NiO and MoO3 oxides due to enhanced charge transfer and promoted formation of catalytically active Ni3+ species. The results highlight the importance of designing ternary oxides in oxygen electrocatalysis.
Abstract
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 NiMoO4 nanorods exhibit a considerably low overpotential of 340 mV at the current density of10 mA/cm2 and a low Tafel slope of 45.6 mV/dec, which is comparable to the benchmark Ru02.Furthermore, the performance of NiMoO4 significantly surpasses binary NiO and MoO3 oxides due to enhanced charge transfer and promoted formation of catalytically active Ni3+ species. The results highlight the importance of designing ternary oxides in oxygen electrocatalysis.
