地球上丰富的过渡金属基纳米材料被认为是最先进的析氧反应（OER）电催化剂。最近的研究表明，非晶材料比它们的晶体形式更活跃。在此，我们展示了一种简单快速的衬底参与方法，在室温下在泡沫铁（a-NiFe NS/IF）上制备非晶NiFe纳米片，作为OER的高效电催化剂。该方法制备a-NiFe NS/IF仅需200 s，电催化剂具有优异的催化活性，在1.0 M KOH条件下，只需要211和240 mV左右的过电位就能达到10和100 mA cm（-2）电流密度。(C) 2019科学出版社，中国科学院大连化学物理研究所。由Elsevier B.V.和科学出版社出版。版权所有。
The earth-abundant transition metal based nanomaterials are regarded as state-of-the-art oxygen evolution reaction (OER) electrocatalyst. Recent studies have shown that amorphous materials are more active than their crystalline forms. Herein, we demonstrate a facile and rapid substrate participation method to fabricate amorphous NiFe nanosheets on iron foam (a-NiFe NS/IF) at ambient temperature as a highly efficient electrocatalyst for OER. This method only takes 200 s to fabricate the a-NiFe NS/IF and the electrocatalyst possesses excellent catalytic activities which only needs overpotentials of about 211 and 240 mV to reach 10 and 100 mA cm(-2) current densities in 1.0 M KOH.
