论文题目为“Pulsed electrodeposition of well-ordered nanoporous Cu-doped Ni arrays promotes highefficiency overall hydrazine splitting”(J. Mater. Chem. A,2020, 8, 21084-21093, DOI:10.1039/d0ta08078k),我院教师孙强强为论文第一作者,我校为论文的第一完成单位。

碱性电解水制氢是大规模工业化制氢的重要途径。然而,电解过程中阴阳两极较大的过电位大大限制了其规模化应用。开发低成本且具有高能量密度、高催化活性的电极材料具有重要的意义。镍铜合金基电极材料因其廉价的成本、丰富的储量以及强烈的金属协同催化作用,在能源转化领域具有广阔的应用前景。

孙强强课题组基于脉冲电沉积法及原位恒电位溶出法,设计了一种具有三维纳米方孔阵列结构的铜合金电极材料(Ni(Cu) CNPs)(图2)。在电解水析氢(Hydrogen evolution reaction, HER)及肼氧化(Hydrazine Oxidation Reaction, HzOR)性能测试中,Ni(Cu) CNPs表现出优异催化性能及稳定性。在10 mA cm-2的电流密度时,析氢过电势仅为41 mV,而肼氧化工作电位仅为-18 mV。应用于实际双功能电解槽,大大降低了电解水的电能消耗,更显著优于市场商用贵金属催化剂(Pt/C),为其在电解水产氢的规模化应用奠定了基础。此外,对阳极催化过程催化机理的研究发现,水合肼在Ni(Cu) CNPs表面中发生两步反应,先氧化失去2电子形成二氮烯,再氧化失去2电子形成气体产物N2,对镍铜合金在直接肼燃料电池(Direct Hydrazine Fuel Cell, DHFC)领域的应用发展具有重要的现实意义。
