【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。更多还原

【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^-2current 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.更多还原
