We report hierarchical CoS/Ni(OH)/NF heterostructure nanorod arrays, which manifest superior bifunctional catalytic activities for the HER and UOR due to amorphous Ni(OH), synergistic effect of multiple components and self-supported structure. The CoS/Ni(OH)/NF-based urea electrolyzer requires a low cell voltage of 1.485 V to deliver 10 mA cm, which is obviously lower than that needed in water electrolysis.
我们报道了分层的CoS/Ni(OH)/NF异质结构纳米棒阵列，由于非晶态Ni(OH)、多组分的协同效应和自支撑结构，该阵列对析氢反应（HER）和尿素氧化反应（UOR）表现出优异的双功能催化活性。基于CoS/Ni(OH)/NF的尿素电解槽在提供10 mA cm电流时需要1.485 V的低电池电压，这明显低于水电解所需的电压。
