摘要
通过水热法高效地制备出三元过渡金属NiCoFe层状双氢氧化物(LDH)超薄纳米片。作为OER催化剂,NiCoFe LDH/NF在1.0 mol/L KOH溶液中表现出卓越的活性和良好的稳定性,当电流密度为120 mA/cm^(2)时,过电位仅需200 mV,Tafel斜率为82 mV/(°),相较于常规水热法制备的NiCoFe LDH,合成温度低、时间短,且性能非常优异。
In this work,ternary transition metal NiCoFe layered double hydroxide(LDH)ultrathin nanosheets were efficiently prepared by hydrothermal method.As an OER catalyst,NiCoFe LDH/NF exhibits excellent OER activity and good stability in 1.0 mol/L KOH solution.When the current density is 120 mA/cm^(2),the overpotential is only 200 mV and the Tafel slope is 82 mV/(°).Compared with the conventional hydrothermal method,the NiCoFe LDH/NF synthesized in this paper has the advantages of low synthesis temperature,short synthesis time and excellent performance.
