제목 Trimetallic NiCoFe-LDH nanosheets as efficient electrocatalyst for urea oxidation reaction
초록 The electrochemical urea oxidation reaction (UOR) is useful for the simultaneous elimination of urea-rich wastewater and generation of hydrogen. In this work, we demonstrated the synthesis NiCoFe-LDH nanosheets supported on 3D Ni foam substrates by one step hydrothermal method. Benefiting from the synergism of compositional and structural merits, the resultant self-supported NiCoFe-LDH/NF composite exhibited excellent electrocatalytic performance for UOR. Significant enhancement of electrocatalytic activity of NiCoFe-LDH/NF was witnessed because of the doped Fe. Compared with the parent NiCo-LDH/NF, the optimized NiCoFe-LDH/NF exhibited a lower overpotential of 109 mV at 25 mA cm−2 with a smaller Tafel slope of 43 mV dec−1 in 1 M KOH containing 0.33 M urea.
