| 摘 要： | 经一步水热法在泡沫镍（NF）上原位生长获得了AlCo-LDH/NF （LDH=层状双氢氧化物）催化剂。基于AlCo-LDH的高表面积和良好相界面，催化剂表现出了优异的电催化析氧反应（OER）活性。在碱性介质中，当电流密度为200 mA·cm-2时，AlCo3-LDH/NF催化剂具有419 mV的低过电位和50.04 mV·dec-1的低Tafel斜率。

| Abstract: | The AlCo-LDH/NF (layered double hydroxide, LDH) catalyst was obtained by in situ growth on nickel foam (NF) by a one-step hydrothermal method. Benefitting from the transition metal-based LDH, as-synthesized AlCo-LDH in-situ grown on nickel foam (NF) electrocatalyst exhibited outstanding oxygen evolution reaction (OER) performance with an exceptionally low overpotential of 419 mV at 200 mA·cm-2 current density in an alkaline electrolyte, an extremely small Tafel slope (50.04 mV·dec-1) and excellent durability, which is due to its high surface area and optimized phase interfaces. |
