This proposal studies the magneto-electrodeposition of tailored conical nanostructures of ferromagnetic Co-Fe-Ni based alloys. Due to their specific structure, nano-cones are attractive for very different applications, including magnetic, super-hydrophobic or electrocatalytic materials. By the ability to switch-on and off two different forces, the Lorentz and the magnetic gradient force, magnetic fields introduce unique possibilities to control the mass transport of both electroactive ions and crystal modifier directly at the conical structures. The vision is to establish a novel and simple route toward ordered arrays of ferromagnetic alloy nano-cones with improved electro-catalytic properties.To approach this vision, systematic experimental and numerical investigations of all relevant electrochemical and hydrodynamic aspects will be conducted on the full length scale hierarchy, from mm to nm range. While the German team is in charge for the hydrodynamics of the electrodeposition process on the millimeter and micrometer scale, the Polish team is responsible for the characterization of the morphological and electro-catalytic properties achieved on the nanoscale. Complementary numerical simulations will be performed by the German team. Based on improved understanding of physics and scaling of the magnetohydrodynamic microconvection and the mass transfer at conical structures as well as on detailed characterization of the morphology and the properties of nano-cone arrays deposited in magnetic fields, models and techniques will be developed towards ordered arrays of electrocatalytic, ferromagnetic nano-cones in a single electrodeposition step.

该方案研究了铁磁性Co-Fe-Ni基合金定制锥形纳米结构的磁电沉积。由于其特殊的结构，纳米锥在磁性、超疏水或电催化材料等领域具有广泛的应用前景。通过开启和关闭两种不同的力，洛伦兹力和磁梯力，磁场引入了独特的可能性，直接在锥形结构上控制电活性离子和晶体调节剂的质量传输。我们的愿景是建立一种新颖而简单的方法来获得具有改进的电催化性能的铁磁合金纳米锥有序阵列。为了实现这一愿景，我们将在从毫米到纳米的全长尺度层次上对所有相关的电化学和流体动力学方面进行系统的实验和数值研究。德国团队负责毫米和微米尺度的电沉积过程的流体动力学，而波兰团队负责纳米尺度上实现的形态和电催化特性的表征。德国团队将进行互补的数值模拟。基于对磁流体微对流和锥形结构传质的物理和尺度的进一步了解，以及对在磁场中沉积的纳米锥阵列的形态和性质的详细表征，将在单一电沉积步骤中向电催化、铁磁纳米锥有序阵列发展模型和技术。
