中文摘要:
      本文系统研究铁在三种低共熔溶剂中的电沉积行为以及过电位和氢键给体对铁沉积物形貌的影响。研究结果表明,在DES1和DES2中,过电位对铁沉积物形貌没有明显影响,但在DES3中过电位对铁纳米粒子的形貌有显著影响。此外,研究结果还证实了氢键给体的种类对铁沉积物的形成有着密切的联系:尿素氢键给体有助于片状网络结构铁膜的形成;乙二醇氢键给体有助于准球形铁纳米粒子的形成;而乙二醇和丙二酸氢键给体的协同作用有助于空心球和类毛线球状等纳米粒子的形成。
Electrodeposition of Iron Nanocrystals from Deep Eutectic Solvents: Effects of Overpotential and Hydrogen Bond Donor on Morphology
英文关键词:iron nanocrystals  electrodeposition  deep eutectic solvents
英文摘要:
      In the present paper, we systematically studied the electrodeposition behaviors of iron, as well as the effects of overpotential and hydrogen bond donors on iron morphology in three deep eutectic solvents. It has found that the overpotential has no effect on iron morphology in DES1 and DES2. However, the overpotential plays an important role in shape evolution of iron deposited in DES3. In addition, this study shows that changing the hydrogen bond obviously affects the morphology of the iron deposited: The presence of urea hydrogen bond donor is conducive to the formation of film with flake network structure; and ethylene glycol hydrogen bond donor can facilitate the formation of quasi-sphere; while with the synergy of ethylene glycol and malonic acid, hollow nanospheres and yarn ball-like nanoparticles are beneficial to form.
