Project period: 04.2018-04.2021
Profile:
This project 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.
